The ball mill is a rotating drum containing steel balls. The raw materials are fed into the mill and the grinding process begins as the steel balls grind against each other. The rotational speed of the mill is between 50 and 100 RPM. Different types of alloyed steel balls are used for producing different grades of cement.
