The charge is lifted to an angle safe for the mill between the plant specific cascading angle and below 90°, and the mill is then moved back and forth with varying speed and acceleration to displace the charge in a controlled manner. The angle and controlled move-ments are designed to break up the frozen charge and

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,
