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. As well, mills with different length to diameter ratios for a given power rating will yield different material retention times, the longer units being utilized for ...

How Slurry Transport inside a Tumbling Grinding Mills

The transport of slurry through the ball-bed in tumbling mills depends on the distribution of voids inside the charge and the speed of the mill. When balls of different sizes are present in the mill, then there is a tendency for the balls to move at different speeds along the axial direction. Ideally, balls would not move in the axial direction if they are of one size.
