Abstract
A grinding mill comprising a rotary cylinder with inwardly-projecting crusher bars on its cylindrical wall is provided with a ball charge in the form of at least ten balls which weigh at least four pounds each, have a diameter of more than about three inches, and occupy in all at least 0.35 per cent and not more than 3 per cent of the mill volume exclusive of voids between the balls. The total charge of material to be ground and balls consists of from 20 per cent to 32 per cent of the mill volume, inclusive of voids, and the drum is rotated about a horizontal axis at a speed of between 84 per cent and 90 per cent of its critical speed. The balls may be made from tungsten carbide or alloy steel. Specifications 632,532 and 696,137 are referred to.
