Ball Size as Initial Charge. Commercial ball sizes 10 – 150 mm; Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., dâ†"V = 0.40 ...

However, there is a great deal of information that describes the variation of the grinding kinetics with the ball size and the ball wear kinetics. It is possible then to incorporate this information into a grinding model and investigate the effect of the make-up ball size on the mill performance with various feed and product specifications.

The specific rates of breakage of particles in a tumbling ball mill are described by the equation Si = axαi ( Q ( z ), where Q ( z) is the probability function which ranges from 1 to 0 as particle size increases. This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by xm = k1d2.

The following are factors that have been investigated and applied in conventional ball milling in order to maximize 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.
