8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Ball mill is widely used in grinding materials in industrial departments like mine, building materials, electricity and chemical engineering. When the ball mill is grinding materials, the liner plate of ball mill receives constant impact and grinding and much abrasion has been caused.
A material's susceptibility to wear depends on its physical and mechanical properties as well as on environmental factors, i.e., the conditions to which the material is exposed .In other words, the wear is a function of the tribosystem (), which is made up of four elements: body, counterbody, interfacial element and environment.The action of each one of these elements can vary, as well as the ...
