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.

Closed Circuit Ball Mill System. Clinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill, discharged and fed to a classifier with the help of a bucket elevator for classification of the ground cement into two streams – coarse and fines.

Compared with opencircuit process, cement material can be processed effectively in the closedcircuit process. of finished product. Just like feeding size of cement raw material, the finer the output material, the lower the capacity of the ball mill; the coarser the finished product, the higher the capacity. Ball Mill Principle. 4 ...
