This change in the circulation regime of mill charge, and hence the grinding performance, should be reflected by an accompanied change in mill power consumption. As a first step, information was obtained on mill power draw as a function of grinding time and slurry density. Dimensions of the batch ball mill used are given in Table 1.

In order to get the most economical consumption of power, the ball load in a Hardinge Mill should be kept up to the level of the trunnions. The capacities, power requirements, etc., of the various sizes of Hardinge Ball Mills are given in Table 12. It should be noted that the two figures describing the size of a mill represent the diameter of ...
