There are three types of grinding media that are commonly used in ball mills: • steel and other metal balls; • metal cylindrical bodies called cylpebs; • ceramic balls with regular or high density. Steel and other metal balls are the most frequently used grinding media with sizes of the balls ranging from 10 to 150 mm in diameter [30].

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.

Flaking and pitting modes do not develop normally during grinding of ore in a ball mill because abrasive wear proceeds at a faster rate. Steel balls abrasion. The abrasive wear of the steel balls determined from the pin-on drum wear test ranged from 0.577 to 1.094 mm³/m. However, the most abrasion resistant type of balls, B1, had too …
