How to Improve Ball Mill Grinding

2020-7-16  Functional performance analysis of ball milling has been described previously by Mclvor. “Coarse” versus “fine” or product particle cut-off size is first selected, usually equal to some benchmark passing size of the circuit product (e.g., 80%). The function of the grinding circuit is to generate new product size material (or “fines”) from “coarse” particles in the circuit feed

The cumulative grinding rate through the size of interest is the identical parameter as the ball mill grinding rate calculated from the functional performance equation. Its maximization is the technical optimization criterion for ball sizing studies.

Study on the Performance of Ball Mill with Liner

The breaking performance of the hemispherical lifter and the ladder lifter was poor, because the main pattern of motion was grinding rather than impact breakage. Secondly, the effects of the height–width ratio of the rectangular lifter, the height of the lifter and the number of lifters on the working efficiency of the ball mill were studied.
