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].
standard cement production process, rather than using conventional fuels and raw materials. A cement kiln producing clinker (the main constituent of cement), is by its nature an efficient tool for the recovery of minerals and energy from waste. Below are some reasons why. Kilns allow for complete burn-out of waste-derived fuel due to:
