Jigging Mineralization is in the role of vertical alternating medium flow, then the ore particles loose, and then by the density difference stratification: light minerals in the upper, called light products; heavy in the lower, called heavy products, so as to achieve sorting purpose. The density of the medium increases within a certain range, the greater the density difference between the ore particles, the higher the efficiency of sorting. In the vertical rising water of the jig, light, heavy, and different sizes have different motions, and heavy minerals fall behind the light minerals and rise below the light ore The When the ore particles reverse movement, in the still or descending water flow, the heavier ore particles will settle at a greater speed, resulting in the formation of light and heavy ore particles: the density of large particles in the lower layer close to the jump The sieve plate of the machine, so that after repeated repeated stratification tends to be clear, and then use the appropriate device will be the severity of the two layers of mineral separation, resulting in two products: concentrate and tailings. Jig type more, according to the jig of water generated within the rise and fall of vertical alternating movement in different ways, the jig can be divided into the following four: Eccentric connecting rod jig (including piston jig and diaphragm jig), no piston jig, hydraulic agitator, moving sieve and so on. At present, the concentrator is mainly used in the diaphragm jig. According to the different location of the diaphragm can be divided into: ① on the moving type diaphragm jig (also known as the Code of the type), its diaphragm room in the upper part of the body; ② under the type of conical diaphragm jig, Under the room; ③ side of the diaphragm-type jar, its diaphragm is located in the side of the jaw room, including trapezoidal jig, rectangular jig and so on. No piston jig The water movement is not driven by the piston or diaphragm, but the compressed air sent by the blower makes the water move up and down. This jig is generally used in the coal preparation industry. Moving sieve jig is the use of sieve in the water up and down movement, resulting in rising and falling water. Some of our small-scale factory's simple hand-cranked jigs belong to this type.

As a leader in mining machinery manufacturing enterprises, Henghong production of mining machinery and equipment naturally not only one, for hundreds of different mining machinery and equipment, how to do their lubrication work? Heng Hong as a design and production of sales enterprises, this is naturally clear in the chest 1, all kinds of crusher in the most common size of the gear lubrication, The size of the gear lubrication can be spray lubrication. The specific method is to compress the air through the oil mist evenly into the gear of the meshing point, the use of oil lubrication and compressed air cooling at the same time, play a lubrication effect. The choice of the size of the gear lubricant is also required, according to its characteristics of the work of more choice of high viscosity, strong adsorption, extrusion wear resistance and has a lattice crystal structure of solid lubricants. 2, rotary kiln main reducer lubrication Rotary kiln main reducer lubrication mainly used bath oil splash lubrication and thin oil lubrication station two. One of the thin oil lubrication station installed in the kiln, can effectively avoid heat radiation, thereby reducing the impact of heat radiation on the quality of lubricants. 3, grate cooler lubrication Grate cooler drive reducer lubrication Henghong recommended selection of oil splash lubrication method, and wheel and wheel bearings lubrication is recommended to use dry oil centralized lubrication way. 4, the cement plant large conveyor transmission parts of the lubrication The lubrication of the large-scale conveying machinery transmission parts of the cement plant is generally lubricated by the oil-soaked splash lubrication method. The bearings are lubricated by the oil cup grease. The large-scale fan drive and the bearing in the cement plant adopt the forced lubrication method of the thin oil station. 5, ball mill lubrication Ball mill lubrication of the main choice of thin oil lubrication station lubrication and cooling the way, and the main bearing or sliding bearing lubrication can be used high and low pressure oil lubrication station cycle lubrication and cooling. Among them, the ball mill start and stop the period of lubrication is recommended in the sliding bearing input high pressure oil, making the slip ring floating method, which can make the oil to form a static pressure oil film effectively reduce the starting torque, to avoid the speed is too low Resulting in direct contact between the slip ring and the slide, reducing the wear of the slide shoe and prolonging its useful life. Henghong remind you that in the lubrication process, the need to focus on the cooling of the oil. Can be forced to cool the cooler, the choice of cooler than the same flow standard cooling area several times, in order to achieve the effect of rapid cooling. Different mechanical equipment lubrication methods are also different, choose the right lubrication method, can help equipment better and more smooth operation, improve equipment production, but also effectively extend the service life of equipment.

Tailings Processing Line [Introduction]: Henghong tailings processing line, with the thought of protecting ecosystem and fully using resources, provide a processing for those valuable metal or non-metal tailings. According different property of all kinds of ore tailings, Henghong can design reasonable process and fully find the value in the tailings. [Application]: Henghong tailings processing line applies to processing of various metal or non-metal tailings, including iron, gold, lead-zinc, copper, fluorite, wolfram, phosphate, graphite, bauxite, etc. Iron tailings: the iron tailings discharge from iron ore plant is in large amount, fine size and different types, and complex property, so Henghong use the process of magnetic separation, flotation, acid leaching and flocculation to recover iron. Gold tailings: Henghong usually use all-slime cyanide process and carbon-in-pulp process to recover the gold from gold tailings. As for the gold tailings cyaniding, Henghong will apply the method of dry-tailing stacking. That is, though the process of classifying and dewatering, at the same recycling the water recourses to remove the cyanide in it. Moreover, Henghong will use magnetic separation and gravity separation to remove the iron. Lead-zinc tailings: the main component of the lead-zinc tailings are quartz and suicide sericite. Except the method of stockpiling in tailings pool, dry-tailing stacking and mine filling, Henghong will also apply gravity separation, flotation separation, magnetic separation, gravity – flotation separation, and other process to recycle the valuable elements. Copper tailings: if the copper with high heavy metals content, the separation will be easier and apply the process of flotation. If there exist magnetite in the copper tailings, it will firstly using acid leaching to precipitate the copper, then use magnetic separation accordingly. Fluorite ore tailings: Henghong use the process of flotation to reselect the fluorite, roughing and then cleaning. Before roughing, the pulp and the reagent will be fully stirred. After that repeated cleaning will be proceed. Wolfram tailing: Henghong will apply gravity separation, magnetic separation and flotation separation to recycle the wolfram. The gravity separation is commonly used. Wolfram tailing re-selection process is mainly used spiral chute and centrifugal ore separator to roughing, shaking table and flotation to cleaning. Phosphate tailing: siliceous collophanite mainly include quartz siliceous minerals in gangue mineral, so the floatability of gangue is larger than valuable mineral. Graphite tailings:Henghong will use the process of stage grinding and screening to recover the graphite from tailings. In the process of separation, flotation and shaking table is always used. If we want to achieve comprehensive recovery of several kinds of minerals from graphite tailings, we should combine several separation methods. Bauxite tailings: when deal with the bauxite tailings, flotation separation and magnetic separation is the common process. Moreover, wetting, dry-tailing stacking and mine filling is always used. [Case] There is a forty-year gold plant in Inner Mongolia. In 2002, before the construction of new tailings pool, the gold tailings in the old tailings pool was over 900 thousand ton. The gold content was about 1,665kg, while silver content was about 25t. Henghong practice tailings re-processing line in pulp-in-carbon factory, capacity was 300t/d, recycled gold and silver by using Gold CIP Production Line. In order to improve the target, Henghong applied negative oxygen machine instead of a vacuum pump, and adopted leaching while absorption process. After the process of gold loaded carbon desorption, pregnant solution electrodeposit, the gold concentrate is produced. The indexes comparison as follow: before reformation, gold and silver concentrate grade is 2.83g/t, gold leaching rate is 86.5% while silver is 48%. Finally, gold recovery rate is 80.4% while silver is 38.2%. The process fully exploit the value of tailings and enhances the efficiency of plant.

Its advantage is not only the characteristics of equipment, but also the specific performance in its production operations. We will make a systematical explanation. 1. Reasonable Feed Inlet Design In order to improve the production of equipment, the large diameter of the equipment inlet is designed, which lays a solid hardware foundation for the production increase. 2. Maximizing the Crushing Ratio Crushing ratio is a performance index evaluating whether the crushing size of the crusher is intact or not. In general, the larger the crushing ratio of the device is, the more uniform the crusher size it exhibits after the material is crushed. The parameter quantum of crushing ratio is very large, which is recognized by the mining industry. 3. Tendency of Simplification of the Overall Structure Reasonable structure is also one of the direct causes of its popularity. Going with the tide of contemporary large-scale equipment, the overall design structure of the jaw crusher is moving in the direction of simplification and miniaturization. 4. High Reliability and Stability of the Working State The operating condition of the equipment is the basic way to increase the output of the equipment, and it is also the most effective method to improve the equipment production efficiency and production capacity. The working condition is very stable and reliable, which is evaluated by the industry insider.

Material blockage problem will affect the equipment production efficiency or even results in serious failure and damage of crusher. Therefore, how to prevent and solve the problem of material blockage is very important. Now Fote Machinery gives you answers. 1. Material Processing It is better to make pre-screening and pre-washing operations for materials with large humidity and viscosity to reduce the crushing difficulty. 2. Tightness Degree Adjustment of Triangle Belt With the sheave rotation, a large number of materials can not be crushed and stuck in the crusher chamber because of the much loose triangle belt, resulting in material blockage. Therefore, it is necessary to adjust the tightness to a proper degree. 3. Observe the Running of Eccentric Shaft When the eccentric shaft tightening bushing looses, the eccentric shaft will be stuck affecting the normal running of crusher. So operators must pay attention to the running of eccentric shaft. 4. Install the Alarm Device Running current of belt conveyor is associated with the number of materials in the lower chamber of crusher. Large amount of materials is easy to cause the crusher halt. According to this feature, it is better to install an alarm device in the roll crusher feeding port to connect with the relay. When the belt conveyor reaches the set current value, the relay will pull in. Then the alarm device stops feeding operation timely.

Copper-lead-zinc beneficiation process using mixed flotation - concentrate re-grinding process, can reduce the cost of grinding, and easy to manage, while the application of new non-toxic flotation agents, efficient and environmentally friendly. The process of mixed flotation - concentrate re-grinding is generally applicable to copper-lead-zinc sulfide ore with close relationship, easy dissociation and uneven grain size. Mineral processing process novel, lower operating costs Copper and lead mixed concentrate re-grinding process, without all the ore are fine grinding, saving grinding costs, while the re-grinding of copper and lead concentrate further monomer dissociation, and play a good drug removal effect for the copper lead The separation of the creation of favorable conditions. Strengthen the flotation process, improve the grade of molybdenum concentrate In the rough selection of strict implementation of the pharmaceutical system, control the amount of pharmaceuticals, so that "early harvest early harvest" to reduce the number of cycles and loss of inaction; make full use of the secondary enrichment of foam, and through the appropriate no water, Concentrate the foam to rinse the impurities in the foam to achieve the purpose of enhanced flotation. Production examples Example 1 The left side of the display for the Henghong mine production of the Tibetan lead-zinc ore concentratorthree- dimensional demonstration video, the mine design scale of 600,000 tons / year, 2400 tons of daily processing, the number of days worked 250 days, the project construction in two phases, Design scale of 300,000 tons / year, handling 1,200 tons, the second phase of the design scale of 300,000 tons / year handling 1,200 tons. The beneficiation method adopted in the project is flotation method, and the product scheme is lead antimony concentrate and zinc concentrate. The main design indicators are: yield, lead antimony concentrate 10.9%, zinc concentrate 2.58%; concentrate grade, lead antimony concentrate Pb32.17%, Sb28.11%, zinc concentrate Zn59.9%; recovery, Lead antimony concentrate Pb85.11%, Sb82.59%, zinc concentrate Zn88.82%. Example 2 Yunnan, a lead-zinc ore dressing plant, after the establishment of the plant after the continuous improvement and improvement of the field process, process indicators have been greatly improved, but the late mining depth due to deepening the ore, the nature of the ore changes, lead, zinc concentrate grade The rate of decline. The original pre-flotation process has been unable to meet the requirements of the copper lead and zinc ore sorting, for which the commission commissioned Henghong to do process transformation, Henghong through repeated mineral processing test , decided to use mixed flotation process, priority flotation of copper Lead concentrate, copper and lead concentrate re-grinding and then floating, accompanied by Henghong homemade lead-zinc copper mine equipment, Henghong full-section air-lift micro-bubble flotation machine instead of the original flotation machine , after the transformation, the The main process indicators are as follows: Contrast before and after transformation Process Processing ore quantity t / d Copper recovery /% Lead concentrate grade /% Zinc concentrate grade /% Equipment lining life / days Transformation of the former Priority flotation 500 78.53 35.68 83.49 50 After transformation Mixed flotation 680 83.45 50.13 84.68 90 Through this transformation, the concentrator can increase the output value of nearly 3 million per day, the daily profit increase of 26,000 yuan, 300 days per year by production, the annual profit increase of 26,000 yuan × 300 days = 7.8 million yuan, its economic benefits Very significant. Example 2 Henghong copper lead and zinc mineral processing technology can focus on the program comparison, investment costs and comprehensive utilization of minerals, at home and abroad to complete the case nearly 100 sets of its technological achievements received international customers praise. In these copper and lead-zinc application cases, the representative of a company in Xinjiang copper and lead-zinc mine, the symbiotic relationship between the mine, Kemei small size, using the original process, copper and lead concentrates each containing excessive, affecting the enterprise economy benefit. Henghong through the improvement of technology, selection of efficient equipment, the final indicators of good, up to standard production. As the ore in the copper, lead mineral symbiotic relationship, the nature of the complex ore, Henghong after a comprehensive analysis of the nature of ore, decided to use part of the priority flotation new technology. First, on the basis of the original preferential flotation process, the preferred collector is used to obtain the copper concentrate, and then the mixed flotation is carried out. The mixed concentrate is re-ground, Degree to -38μm78%, to improve the copper-lead mineral monomer dissociation, to copper-lead mineral separation conditions. Henghong transformation process is simple, low production costs, copper concentrate recovery rate of 90.21%, lead and zinc are qualified, lead concentrate recovery rate of 88.3%, good quality. Copper, lead concentrate with low, the recovery rate than the original process greatly improved, while the recovery rate of zinc concentrate is also significantly improved by the other highly praised. Through this cooperation, good equipment performance, coupled with thoughtful after-sales service, partners witness the strength of Henghong, looking forward to the next plant and Henghong company's cooperation. In recent years, Henghong company and domestic large enterprises more and more cooperation, and domestic large enterprises, mining cooperation, to enhance the Henghong company's service level, exercise the installation team, but also contract more foreign total Package works, expanding the Henghong company's influence. Other representative cases: Henghong copper lead and zinc mineral processing technology is still a lot of cases, we welcome the majority of users to my company for field inspection, we will also accompany you to study the same type of production line we have done, with the facts that everything: Northwest of a copper lead and zinc concentrator, Henghong in the absorption of priority and mixed flotation process on the basis of the advantages of close combination of ore characteristics, the use of partial preferential flotation of new technology, access to good mineral processing indicators, including lead concentrate grade up to 66.52% , The recovery rate of 88.5%, to the same industry advanced level. Sweden, a copper lead and zinc concentrator, the daily output of 1000t, copper 0.58%, lead 2.85%, zinc 4.90%, on-site production using copper and lead floating process, copper and lead mixed concentrate after the release of activated carbon, with copper collector Copper and lead separation flotation, by a rough three fine operation, can get copper concentrate 20.25% copper, lead 6.75%, lead concentrate lead 58.73%, copper 3.40%. Inner Mongolia, a copper lead and zinc concentrator, mainly copper, lead, zinc, there is a certain amount of magnetite, Henghong according to the nature of the ore, carried out a series of mineral processing experiments, the final decision of copper and lead mixed floating re-separation - Election - flotation tailings weak magnetic separation process, in the high-grade copper, lead, zinc concentrate at the same time also get more than 65% iron ore.

Flotation is the most widely used mineral processing method for the treatment of rock and gold in gold concentrator , and is often used to treat highly depleted sulfide mineral gold-bearing ores. Flotation process can maximize the enrichment of gold to the sulfide minerals, tailings can be directly abandoned, low cost of mineral processing, 80% of China's rock gold are used to sort out the process. Gold flotation process is suitable for the treatment of gold particles smaller, floatable high sulfide quartz vein ore and polymetallic gold sulfide ore and carbon (graphite) ore. Gold flotation process Gold flotation of the general use of a grinding - flotation process, can be used for the uneven size of the ore can be used stage grinding process. China generally adopted a grinding - flotation process, in order to achieve the enrichment of useful minerals. Gold fineness requirements Gold ore fineness requirements, in general, for the package in the sulfide minerals in the gold only need to dissociate the sulfide monomer can be, but with the gangue gold grinding fineness of the gold need to reach the monomer Dissociation. At the same time a certain kind of mineral grinding degree of fineness is determined by the test. Gold ore flotation process pulp concentration requirements Gold flotation principle is: flotation large density, coarse particle size, often with a thicker pulp; the other hand, when the flotation of small density, fine particle size and slime with thinner slurry, coarse selection of thicker Pulp, can guarantee a higher recovery rate, selected with a more dilute concentration, is conducive to improving the quality of the concentrate. Other process conditions In addition to grinding fineness, the impact of gold flotation process conditions, including pulp concentration, flotation agent dosage, inflatable, flotation time and so on need to test to determine. General gold flotation process, the need to use the flotation agents are: collector, activator, foaming agent, etc., collectors used to promote the gold floating, the activator is to increase the floating rate of gold, foaming agent Is to increase the number of flotation bubbles. Production examples Taking a gold mine in Yunnan as an example, the size of the plant is 300t / d, the main mineral in the ore is pyrite, the grain size of gold is fine, and it is closely related to the metal sulfide mineral. The flotation process of the ore is a rough selection, twice selected, two sweeps, but because arsenic antimony mineral surface is easy to be oxidized, adsorption of a large number of flotation agents, and the flotation effect is poor, so the election plant Commissioned Henghong to transform the flotation process.Henghong for the original production problems, combined with the actual production, the process of technological transformation, the original gold ore flotation equipment cyclone tail to stage grinding, flotation throwing tail, so that the process is smooth, easy Operation, in addition, the number of equipment for some of the equipment and flotation system are improved, the final indicators of good results. Before and after the transformation of specific indicators are as follows: Product name Gold concentrate grade / (g / t) Gold Recovery /% Transformation of the former Gold concentrate 33.35 90.62 Tailings 0.68 9.38 Ore 3.32 100 After transformation Gold concentrate 34.38 81.80 Tailings 0.34 19.20 Ore 3.30 100 The original gold ore flotation process to stage grinding process, easier to operate, for the higher minerals in the possession of minerals to do early harvest, fast income; adjust the flotation machine structure, improve the sorting environment, But also improve the flotation slurry mineralization effect, to ensure the stability of the indicators and flow of the program.

How to Used Gravity Separation Equipment Beneficiation Sand Gold Ore? Sand gold panning method is relatively simple, generally by screening, washing, select the final gold concentrate can be obtained, the actual production needs to be determined according to the characteristics of mineral gold election process and equipment configuration. Such as sand gold ore ore content of the larger need to properly wash the mine to get rid of mud, to avoid the gold particles wrapped in mud caused by the loss. If the gold content is very low, less than 0.3g / t gold content is the best after the first pre-enrichment, such as chute or spiral chute enrichment, the gold content to a certain degree of enrichment and then into the jig and other rough selection equipment, Can be done by shaking the rough, medium, selection. Such as the amount of alloy is very high, preferably directly into the shaker to complete the selection, to avoid chute rough selection caused by the loss of gold, etc., which are based on the actual situation and determine the content, not all sand gold can be generalized, The gold process does not apply to all gold deposits. 1, gold ore beneficiation screening equipment Placer gold ore contains a large number of non-gold pebbles and waste rock, affecting the efficiency and effectiveness of gold beneficiation, so the need for the gold ore sieve screening, commonly used screening equipment has a roller screen and vibrating screen, the advantage But also the need for the gold ore ore washing, it will also use both washing and screening role of the drum washing machine. 2, sand gold ore beneficiation gravity equipment Gravity separation method is the most important gold ore dressing equipment, all of the rough separation gold ore are Gravity separation by the method, the commonly used sand gold Gravity separation equipment are shaking table, jig, spiral chute, centrifugal separator, etc. Because of the handling capacity of the rough selection basically through the jig,spiral chute, or centrifugal separator, shaking table is often used as a selection of placer gold, but the shaker is used rough Selection,middle selection, fine selection, sweep separation in a device, the election in the use of universal operations.

Cone ball mill in the work of running, we must meet these two objectives. The grinding effect of a warehouse can directly affect the effect of the various positions behind, and even affect the production of grinding.Therefore, in the cement mill can achieve the best grinding state, first of all depends on whether a warehouse to achieve a certain grinding standard. There is also a focus on a liner within the liner and the ball is also very critical, the degree of material crushing must have their cooperation to decide. Cone ball mill in the first position played a key role in the whole process, cone mill in the production process, mainly using our latest technology, whether to achieve the best grinding results, Directly by crushing power to achieve the broken material. In the cone ball mill, the crushing of the material is the main role of the first warehouse, but also the key role of the grinding process. Therefore, the first position is very important for a warehouse, but also with the main purpose of machine. Customer installed a new ball mill in the running-in process, the amount of the ball in the process of the first added, accounting for ball mill ball loading capacity of 80% of the steel ball can be added to the proportion of steel ball size (Φ120㎜, Φ100㎜ , Φ80㎜, Φ60㎜, Φ40㎜) size to add. Different ball mill models with different loading steel ball. For example, model 1500 × 3000 ball mill the maximum loading steel ball of 9.5-10 tons. The first time can add big steel ball (120 mm and 100 mm) accounted for 30% -40%, the medium steel ball 80mm accounted for 40% -30%, the small steel balls (60 and 40 mm) accounted for 30%. Under normal circumstances, we run the ball mill in the process, the amount of steel balls to add only 80%. This is because the cement mill installed, the size of the ball mill meshing need to deal with the volume is to gradually increase to the normal operation of the ball mill for two or three days, check the size of the gear check meshing conditions, to be all normal, open the second hole manhole cover Add the remaining 20% steel balls. The addition of a small ball is only the first time with the ball with. Because the normal operation of ball mill ball and steel ball, steel ball and ore, ball and ball mill liner generated between the reasonable friction, will increase the wear, so that a large ball mill, ball mill for the ball. So usually under normal circumstances, do not need to add small ball. Add the ball in the case of useful mineral particle size without monomer dissociation, when the fineness of the grinding machine can not reach the flotation requirements, you can add an appropriate amount of small balls. So usually under normal circumstances, do not need to add small ball. Add the ball in the case of useful mineral particle size without monomer dissociation, when the fineness of the grinding machine can not reach the flotation requirements, you can add an appropriate amount of small balls. Cone ball mill to add a direct impact on the interests of customers in the cone-ball mill of the consumable parts, the ball accounted for most of which consumed, and the consumption of a direct impact on the interests of customers, so a reasonable ball is added A work that requires skill. We need to understand the focus is: the ball added weight is based on the quality of steel balls, ball quality is good or bad, decided to add tons of ore consumption, the best use of new wear-resistant steel ball, such as the train wheel hub with special Dealing with forged from the ball on the special wear-resistant, which need to be applied according to the actual situation.

The re-election method is the main method of tin ore beneficiation for a long time. The tin mineral exists in the ore with uneven thickness, and the density of the tin mineral is much larger than the associated gangue, so most of the tin ore is suitable for heavy Select purification, especially coarse-grained embedded tin, re-election method is the most ideal method. With the development of mineral processing technology, this year also appeared for the tin ore flotation method, but the end due to the relatively weak applicability, flotation agent expensive and other reasons, flotation in tin ore beneficiation application is rare , Re-election method is still the mainstream of tin ore dressing method. Tin ore beneficiation method is divided into re-election and flotation, tin ore processing equipment will be divided into re-election equipment and flotation equipment. Tin ore re-election equipment refers to the jig, shaking table,Spiral Chute and other equipment, jig for tin ore preselected enrichment, shaker is as a selection of equipment purification, some coarse-grained tin ore dressing can also jump The machine has the advantages of large processing capacity, high recovery rate, and is suitable for the roughing and selection of tin ore beneficiation, while the shaker covers a large area and has a small processing capacity. It is only used as the concentrate of tin ore dressing. Select the device. Flotation equipment, including crusher, ball mill, grading machine, mixing bucket, flotation machine, flotation equipment investment, production costs are high, so for tin ore beneficiation re-election - flotation combined process and Equipment to reduce equipment investment and production costs, re-election equipment in the field of tin ore processing plays an extremely important role.

The size of the steel balls in the ball mill depend on the physical and mechanical properties of the ore and ore particle size composition of these two elements. Henghong Mining Machinery will answer you the loading ball precautions in ball mill by following notes. 1, processing hardness of coarse grained ores, need to have a greater impact, need the ball into a larger size; ore soft ore particle size smaller, product size is fine, then the grinding, can be loaded into the smaller size of the ball. 2, the production site in a variety of ball mill ball size ball, according to a certain proportion to the processing of different size particles composed of material. Theoretically, only to ensure all kinds of balls have a certain proportion, the size and composition of the material to be ground to get good grinding effect.

The main function of the ball mill lining board is to use of the surface of the lining board and the convex peak of the grinding ball, and the material is repeatedly crushed and grinding. Whether the selection of lining material is suitable for the performance of the ball mill has a great influence. Henghong Expert will mainly introduce the selection principle and method of lining material. Select the material must be based on different conditions to determine the different material, that is used in the fine grinding bin or coarse grinding bin. Fine grinding chamber is based on the pattern of the lining board, small corrugated liner, flat panel and other forms of the main. The role of the rough mill and the fine mill is different, the size of the ball is different, and the impact of the lining plate is very different. Equivalent mill diameter, coarse grinding bin of large diameter, material size is large, the impact of the lining of large, high wear speed, fine grinding position of the situation is much better. Selection principle: material relative wear resistance or the service life of high strength and toughness; there are appropriate, to ensure the safety and reliability of the lining board in the work process is particularly important; in addition to considering the liner itself production costs, but also consider the installation fees, parking fees to replace the lining board, labor service fees, auxiliary materials consumption and productivity and other aspects. The domestic and foreign research on lining material has been carried out, there are 40~50, wear resistant steel material in China has been in industry production process, mechanical properties and application results of each are not identical, now has formed the process characteristics of multi variety and small batch. After practice, the fine grinding barn, better effect of medium carbon alloy chromium manganese steel is generally used. In the coarse grinding storehouse ball mill in the range of 3~5 m in diameter should choose medium carbon low alloy wear-resistant chromium manganese, its effect is very good, the economic benefit is also very good. For less than or equal to the diameter of ball mill 3 meters, the coarse grinding chamber should choose high chromium cast iron multi alloying, this material is safe and stable, but also has very good abrasion resistance.

The liner is an important component of a more serious wear of ball mill, loss of large amount of influence factors in ball mill lining technology consumption up to a dozen or more, but the basic constant. Henghong machine think that how to choose the appropriate ball mill lining plate, is an important step to ensure the ball mill lining plate the use of life. Throughout most of China's metallurgical mine mill plant wet milling coarse grinding machine is almost 100% of the metal liner board, which is given priority to with high manganese steel lining plate. Metallurgy mine wet grinding fine grinding ball mill liner, has been to the development of diversified materials, in addition to the metal plate, rubber lining, pu (PVC) lining board, composite materials with different magnetic lining board arises at the historic moment. Cement industry and metallurgy ore mill work situation is slightly different. First of all, ball mill speed is low, the former is more critical speed of 75% ~ 80%. Secondly, slender cement ball mill, which is short and thick. Finally, the cement head the ball diameter and the latter is much smaller than the ball diameter. Therefore, cement ball mill lining board selects the impact hardening of high manganese steel is improper, should vigorously promote chrome alloy plate. Through Henghong machine of nearly hundred large, medium and small cement plant ball mill lining board track inspection confirmed that sums up some useful ball mill lining board selection advice, for your reference. Large diameter cement mill 3.5 x 5 meters, low alloy carbon material suitable for grinding, cylinder liner, can be high, low chrome multielement alloy cast iron, partition board by medium carbon low-alloy steel, cement mill, diameter of 2.4 ~ 3.5 meters, in the selection of grinding carbon, low alloy steel right, cylinder liner, low chromium cast iron, partition board in carbon steel is feasible. Small cement mill diameter of 2.4 meters below, with carbon steel with low chromium cast iron grinding head of insurance, also, the cylinder with high and low chromium cast iron without problems, life of 3 to 5 years. The partition board with carbon steel in cement industry is good, all the ball mill lining plate containing parts the positions are not using non-metallic liner, the main reason for dry grinding, and high temperature. Select the appropriate lining board is very important for the ball mill, to choose a suitable ball mill is equally important for the cement factory scale manufacturers, production capacity, product quality, equipment parameters, product price, customer service service, like less.

Make useful minerals in the ore monomer dissociation, is to use any mineral processing method to solve the key problems, first as a result, the flotation condition test generally begin with ball mill grinding fineness test. Based on the characteristics of mineral disseminated extent identification results, can preliminarily estimate the grinding fineness, but must be determined by the experiment. Ball mill grinding fineness trials often, take more than three samples with different time (for example, 10 min, 12 min, 15 min, 20 min, 30 min), while keeping other test under the same grinding conditions, then carries on the flotation, compare the results. In parallel at the same time to take a few core sample, respectively with specified above several grinding, grinding time and grinding sieve analysis, find the grinding time and the relationship between ball mill grinding fineness. Sometimes also can choose the better one or two conditions, take one or two of the same time of grinding the core sample accordingly, sieve analysis. Determine the grinding time and relationship between ball mill grinding fineness of particular way is: sampling after dry grinding, generally is 100 g, and in 200 to wet sieve sieve. Oversize product after drying, and then inspection on 200 sieve sieve, measured is less than 200 purpose of material before and after merger. Can be calculated accordingly - 200 mesh level of content in the grinding. Then the grinding time (min) as the abscissa, ball mill grinding fineness (- 200 mesh level of content, %) as the ordinate, plot of relationship.
