Cement mill – Cracks in the mill ends
balls (grinding media) of various sizes. During operation, cement clinker that has been baked in the rotary kiln is fed into the mill through the input shaft. The cylinder rotates at approximately 15 rpm, with the result that the clinker is ground into cement powder by the impact and friction of the grinding media. Schematic diagram of a cement
