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.

Grinding Cylpebs For Ball Mill. Grinding cylpebs is a type of grinding media with a short cylindrical or truncated conical shape. Just like the grinding ball, it can also be divided into the metallic type and non-metallic type.In large-sized industrial ball mills, we mostly adopt metallic grinding cylpbebs which include cast steel cylpebs and forged steel cylpebs.
