The increased metal wear of grinding media and mill liners for wet grinding equalizes the additional energy costs of the dry grinding procedure. When dry grinding cement raw material, a protective coating of ground material covers the mill liners and grinding balls. It is known that cement raw material is much less abrasive than cement clinker.

Cement has a high affinity for water. So upon contact with water, the dry cement powder acts like a sponge and globs up. The balls form as these globs roll against the inside drum surface. The key to prevention is to program a material-loading sequence that deposits the cement and the coarse aggregate into the drum at the same time.

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.
