For instance, in large diameter ball mills, the impact force of the grinding media is so great, that a high material surface unbalance prevails in the mill when grinding all types of clinker, thus requiring a grinding aid at all times. The higher the fineness, the more grinding aid that must be used to restore the feed particles to a balanced ...
