Ball Mill Parameter Selection Calculation - Power ...

2019-8-30  1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and

1991-10-1  Abstract The present study deals with an analysis of the selection function for mills using balls as grinding media. The grinding mechanism assumes that a particle caught by two colliding balls will be ground only if the ball impact generates or activates at least one single crack within the particle causing the fragmentation. The derived selection function becomes convex in relation to ...
