The Effect of Ball Size Diameter on Milling Performance

size reduction. The diameter of the balls used in ball mills play a significant role in the improvement and optimization of the efficiency of the mill 4. The optimum rotation speed of a mill which is the speed at which optimum size reduction takes place is determined in terms of the percentage of the critical speed of the mill

FREDA REBECCA SAGMILLING CIRCUIT OPTIMIZATION

This work is aimed at optimizing the SAG mills feed size distribution as this is an important parameter that affects milling performance after ore competency. A lot of operations have recognized the optimization opportunity that can be taken advantage of by manipulating the feed size distribution to improve SAG milling efficiency.

ore size reduction optimisation ball mill

In one of the PGM plant surveys the ball mill feed F 80 size was 17.8 mm and the ball mill product P 80 size was 0.19 mm achieving a size reduction ratio of 94 in one stage grinding. A very long residence time is required for the slurry to be retained in the mill for sufficient size reduction but at a cost of reduced mill productivity.
