  • Vertical roller mill for raw Application p rocess materials

    At the beginning stage when vertical roller mill was adopted to cement manufacturing, mill gas circulation fan and dust collection fan are required and their power consumption was larger Descriptions The conventional process gas flow of the mill grinding system generally consists of vertical roller mill with separator, cyclone, mill circulation fan, and electrostatic precipitator (EP) and EP fan as shown in Fig1The cement mill grinds the clinker to a fine powder A small amount of gypsum a form of calcium sulfate is normally ground up with the clinker The gypsum controls the setting properties of the cement when water is added The basic components of the cementCement manufacturing components of a cement
