ball mill sizing and design

effects of grinding media shapes on ball mill  WIReDSpace
The Bond law of grinding has been widely used for mill sizing and design. The model is an empirical equation based on analysis of data from laboratory and industrial mills. It is based upon the twopower calculation approaches used in majority of ball and rod mill design processes (Smit, 2000) i.e.; a. The determination of

Ball Mill Loading  Dry Milling  Paul O. Abbe
Slice Mills™ are identical to the Ball Mills and Ceramic Lined Mills in diameter and design The only difference is that they are as little as 12” in length. Since mill diameter dictates performance and mill length only affects capacity, Slice Mills™ are used to develop or test formulations with little concern for scale (more)
