The basic principle of jig machine

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.
