Cement mill fan: The cement mill fan is responsible for grinding the clinker into a fine powder, which is then mixed with gypsum and other additives to produce the final cement product. The cement mill fan must be designed to handle high temperatures and the abrasive materials that are present in the clinker. Fig. 1. Kiln process fan.
