vertical roller mill with separator, cyclone, mill circulation fan, and electrostatic precipitator (EP) and EP fan as shown in Fig.1. Pulverized final products, which is called kiln feed raw meal, are collected at the cyclone and EP. Because of large pressure loss at the cyclone and in order to control mill gas flow, mill …
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.
