Grinding media directly affects the load behavior and, consequently, the performance of industrial mills in terms of product size, energy consumption, and grinding costs. ( Lameck et al., 2006) examined the impacts of different media shapes on the load behavior and power draw based on a function of mill filling and speed.
Grinding media. 1. Introduction. Spherical balls are the dominant media shape used in the tumbling mills. However spherical balls wear into non-spherical fragments as a result of breakage due to impact and different wearing mechanisms inside the mill. Thus at any one time a mill charge is a mixture ranging from larger spherical …

Cylindrical grinding media, which have a slightly spherical shape, called Cylpebs have recently been introduced. Comparative tests have been performed using Cylpebs and balls in a laboratory ball mill under the same conditions of mass and feed. Results show that a faster breakage rate is obtained using Cylpebs as the charge.

It was found that the grinding of quartz obeyed the first order breakage kinetics in the case of balls and cylpebs. Cylpebs produced faster breakage rates than ball charges under the same mass and surface area conditions. In addition, the differences between the breakage rates were more significant for coarse size fractions than for fine size ...
