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.
