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.

The M scale uses a 100.00 kg major load and a 0.25 in. (6.35 mm) diameter ball. The E scale, for thermoset materials, uses a 100.00 kg major load and 0.125 in. (3.17 mm) diameter ball. The Rockwell hardness number is directly related to the indentation hardness of the plastic material (i.e., the higher the reading, the harder the material).

For the superficial Rockwell scales, the preliminary force (load) level is 3 kgf and the standard total force (load) levels may be 15 kgf, 30 kgf or 45 kgf. The Rockwell hardness test method consists of indenting the test material with a diamond cone or hardened steel ball indenter.
