Do your know how does the raw mill work in the cement plant? 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.
