Calculation of Top Grinding Media Size Ball Sizing
20151014 To do this, a set of “ball size tests” are performed in a batch mill from which the specific selection function dependence on ball size can be determined. Then, the mill capacities used to produce desired product size can be predicted by simulation using the kinetic parameter corresponding to the different ball sizes.

201391 This model gives (6) e j = 1 1 + S j τ 1 1 + S j τ 2 2 where τ 1 is the mean residence of the first reactor, and τ 2 is the mean residence time of the second and third reactor having an equal size. This equation allows the calculation of the product size distribution from a mill once dij is determined.

Ball Mill  an overview ScienceDirect Topics
The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds.

Effect of ball and feed particle size distribution on the ...
201861 The desired size class is selected as the product fineness that is vital for a downstream recovery process. In this case an example size class of 150 + 75 μm can be selected that will maximize the amount of material for a leaching process. The Figure shows that more of the material is obtained for the three ball mixture.
