This paper mainly introduces the raw mill in cement plant. In order to achieve the desired setting qualities in the finished product, a quantity (2-8%, but typically 5%) of calcium sulfate (usually gypsum or anhydrite) is added to the clinker and the mixture is finely ground to form the finished cement powder. This is achieved in a cement raw mill. Grinding is invaluable in carbon steel microstructures 1, metal ore milling 2, cement production 3, minerals 4, powder technology for the The cement enterprises tend to set up their cement clinker grinding plant in the place close to the raw mineral field.Its Production capacity ranges from 200t/d to 8,000t/d.
