According to Cleary (2001), grinding in ball mills is still far from being effective due to high consumption of electrical energy and steel (grinding media). Currently, the cost of steel balls amounts to 45% of the total cost of grinding materials in ball mills (Lameck, 2005). The remaining costs include energy consumption and ball mill lining.

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.

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].

In the case of a cement ball mill, the grinding takes place within a rotating drum filled with grinding media (usually steel balls). The raw materials are fed into the drum and subjected to the grinding action of the rotating balls, which crush and grind them into a fine powder known as a raw meal.
