28.02.2016A wear tester is used to measure the wear of specimen due to ball impacts. A relation is then extracted which gives the wear of specimen at the different impact conditions. This relation is used to evaluate the impact liner wear. Abrasion liner wear is evaluated using the procedure suggested by Radziszewski.

Discrete Element Method simulation of charge motion in ball, SAG and autogenous mills has become a standard for lifter design, power draft evaluation, etc. Both two-dimensional and three-dimensional codes are being used. The two-dimensional code dominates the user market since the code completes a simulation in one or two hours.

Abstract The formulation and verification of the discrete element model for the ball charge motion in a ball mill are described in Part I. Here, the model is used to simulate the charge motion in an industrial size mill.
