in a laboratory ball mill, and concluded that, in wet batch milling, the breakage of larger particles can accelerate, decelerate or remain constant, depending on loading conditions, slurry . density and feed size distribution. Klimpel [11,12] determined both acceleration and the slowing down of breakage in experiments under different operating conditions by a radioactive tracer .
operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between mill absorbed power and ball filling degree. As indied on the graph, a small variation in power could be the result of a significant variation of balls filling degree. As the ball wear rate depends directly on the surface of the media charge, .
