Ball mills can be classified into highenergy ball mills and lowenergy ball mills by their rotation speed. Selection of certain ball mill depends on used technique; MA, MM or MD. However, some ball mills can be utilized for all three of these techniques. Table 2 presents the most common ball mills and their energy types. [1, ] [4] Table 2.

CERAMIC LINED BALL MILL. 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.
