    Effect of Ball Diameter, Or Rod Diameter VariationGrinding Media Density VariationsMill Efficiency & Mill FillingEffect of Balls Hardness Onrate of GrindingSize Distribution of The Balls in The Mill ChargeThe first relationship to be considered is the effect of the variation of the ball diameter, or rod diameter,upon the size distribution obtained. In Fig. 6.1 are shown typical size frequency curves obtained by ball milling; these curves being deduced from the data of Coghill and Devaney. As would be expected, the grinding of a coarse feed with small balls does not give rise to the effective grinding of the coarse particles in the feed but does produce a considerable amount of fine product. For the largest ball sizes,
