Effect of ball and feed particle size distribution on the ...
2018-6-1 In this article the effect of grinding media size distribution and feed material particle size distribution (PSD) on the product fineness requirements were investigated. A model free approach called the Attainable Region method was then applied in order to optimize the product size fineness in terms of the feed size and ball mix.

Ball Mill Roller Press Systems for Cement Grinding ...
The finished product cement from this system has all been further ground in the ball mill, so it has wide particle size distribution and stable performance. However, due to the fact that the materials rolled by the roller press are not sorted, a large amount of fine powder is returned to the roller press.

Feed Size VS Ball Size - Grinding Classification ...
A ball diameter that grabs the particle must exceed the particle by 25 times to achieve this semi-self locking taper. One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum. Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill.
