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.

As a general rule, there should be less than 25% of clinker that is below 1mm in size. Coarse clinker is more of an issue for ball mills. Some cement groups use a formula, such as Bond's, to calculate the maximum ball size required in a ball mill, based on the average size of the clinker feed. However, one drawback with this approach is …

What is a Ball Mill? A ball mill is a type of grinder that uses metal balls or other grinding mediums to reduce the size of various materials. The material to be ground is placed in a cylindrical container that spins on its axis. The metal balls or grinding media inside the container hits the material and breaks it down into smaller particles.
