How to Improve Cement Ball Mill Performance in

From table 1 we can learn that if the particle size of the feed material is reduced from 25 mm to less than 2 mm, the mill output can be increased by at least 60%, which is relatively consistent with the actual production. There are two methods for clinker pretreatment: pre-crushing and pre-grinding.

Effect of ball and feed particle size distribution on the

2018-6-1  The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower. For a finer feed, the 20 mm + 10 mm binary mix is able to break the feed at a faster rate.
