cement clinker fines processing

3. Coal Fines. Many cement plants use bituminous coal as the fuel of rotary kiln, so the ash content, volatile matter, calorific value, fineness, and moisture of coal fines will affect the clinker calcination process in the kiln. Coal fines. Coal fines are usually prepared by air swept coal mill or vertical mill.
