the grinding efficiency of the ball mill

Factors Affecting Ball Mill Grinding Efficiency a) Mill Geometry and Speed Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.
