The working principle of a ball mill is based on the impact and attrition between the balls and the grinding media. As the mill rotates, the grinding media (usually steel or ceramic balls) are lifted to a certain height and then allowed to fall freely, causing the materials to be reduced in size by the impact and abrasive forces generated ...

There are three types of grinding media that are commonly used in ball mills: • steel and other metal balls; • metal cylindrical bodies called cylpebs;
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. The drum is generally divided into two or three chambers, with different ...
