THE OPTIMAL BALL DIAMETER IN A MILL. Let us look back at the optimal ball charge in a mill. The necessary number of balls having the definite diameter N b in a mill should be proportional to grain number N having the definite diameters which they can grind N b N. 7 The number of grains of the material with determined diameters depends on the grain size distribution.
