anhydrite) in a cement mill to control the properties of the cement. Combinations of milling techniques including ball mills, roller mills, or roller presses are often applied to ground clinker with additives in cement mill. The finished cement is being transferred via bucket elevators and conveyors to silo for storage [9].
