Cement Mill Grinding Media Ball Calculation

Ball mill is a cylindrical device that used to grind and blend raw materials and it rotates around a horizontal axis, partially filled with the material to be ground plus the grinding medium.

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].

Cement manufacturing - brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media - normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.
