Investigations were carried out in a laboratory ball mill having the size of DxL = 160x200 mm with a ribbed inside surface of the drum. The mill ball loading was 40% by volume, the rotation rate was equal to 85% of the critical speed. Balls were made from steel: S4146, extra high quality, having hardness 62 ± 2 HRC according to Rockwell.

Thus, the medium could be steel or cast iron balls when the mill is designated as a ball mill, or it could be steel rods where the mill is known as a rod mill. When no grinding medium is charged it is known as an autogenous mill. In this chapter, we initially discuss the design and operation of tubular mills followed by ball mills.

used to avoid the risk of liner and ball damage by projecting balls directly on the shell liner. Figure 3b illustrates this issue. Obviously, a good liner design and the right operating conditions such as mill speed or balls filling degree, should limit the risk of projection.
