Closed-circuit grinding is a size-reduction process in which the ground material is removed either by screening or by a classifier and the oversize is returned by integral classification to the mill for further processing.
Wet Grinding: Open circuit Ball mill or closed circuit Ball mill Dry Grinding: Open circuit Ball mill, closed circuit Ball mill, vertical roller mill, Roll Press or Roll press in circuit with ball mill. However, it would be seen that the most significant process and types used for raw material grinding operations in modern cement industry are: Process: Dry Closed circuit dry-grinding. Type of mill: Ball and tube mills.
Metallurgical ContentOpen Circuit GrindingClosed Circuit GrindingGrinding Circuit Process Control VariablesGrinding Operating Costs The simplest grinding circuit consists of a ball or rod mill in closed circuit with a classifier; the flow sheet is shown in Fig. 25 and the actual layout in Fig. 9.
