open and closed circuit grinding in cement manufacturing The grinding is done by open circuit grinding or closed circuit grinding depending on the fine powder of cement required.
Cement manufacturing is a continuous process industry with very high requirements and performance rates, requiring high reliability in both the process and maintenance. There are two basic types of ball grinding systems: open circuit and closed circuit.
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).
