The cement raw material mixtures are ground, dried, and classified in the Pfeiffer vertical roller mill. For drying the material, hot gases are directed into the mill. Product fineness can be adjusted within a wide range (0.063 to 0.2 mm). The ground and dried product is separated from the process gas in a cyclone collecting system which is followed by the mill fan. Downstream of the mill fan

Cement grinding. The clinker from the pyro-processing area is ground in ball mills or roll press + Ball mill combination or vertical roller mills to form cement. Commonly used separators are in closed circuit grinding are: O –sepa, Sepol and Sepax separators to achieve a finish cement fineness of 3000 – 4000 Blaine surface (cm2/gm).

In the raw material grinding vertical mill, the heat source for drying the raw materials is the hot gas exhausted from the rotary kiln. The cement rotary kiln When operating the vertical roller mill, the operator must control the inlet and outlet air valves to make the air volume of the system in a balanced state, so as not to affect the air pressure at the back end of the rotary kiln.
