The wet grinding experiments were conducted in bench (0.25 m diameter) and pilot-scale mills (0.42 m diameter), and surveys in a full-scale industrial (5.2 m diameter) mill. It is first demonstrated that the successful application of the model required recognizing the non-normalizable nature of the breakage function of the particular ore.

Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

Since there is a strong correlation between load behavior and mill power, load behavior is an essential operating factor that can even be used to control a mill (Austin et al., 1984).Grinding media directly affects the load behavior and, consequently, the performance of industrial mills in terms of product size, energy consumption, and grinding costs.

Ball mills 5.5 m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40% by volume ball charges. This paper will explore factors used in scaling up ball mills, showing where the advantages of one factor can possibly be negated by another factor. The paper will propose …

The primary production time for milling follows the formula T p = (L/S)i min, where L is the total length of passage of the workpiece in mm relative to the cutter in the direction of feed, and i is the number of passes. The allowable cutting speed depends on the type of cutter, the material and geometric parameters of the cutting element and other components, the cutting format, the …
