Exploring Ball Size Distribution In Coal Grinding Mills
May 01, 2014 It has been shown that mill capacity is linearly correlated to media surface area, thus using 30 mm balls as top size which leads to a fine ball size distribution in the mill is evidently a better approach than the current approach of using larger ball sizes. However the fact that the coal feed to this plant is known to be contaminated with a small fraction of hardtogrind stone, which will strongly …

Exploring Ball Size Distribution In Coal Grinding Mills
The effect of the ball size distribution on the milling rate of coal has been measured as a function of ball size distribution. The change in ball size distribution as affected by wear and ball topup policy has been modelled. From this a best ball topup policy can be recommended that will ensure a close approximation to the desired steadystate ball size distribution that gives the required PF size distribution …
