### GRINDING TECHNOLOGY COURSEThe Cement Institute

This course covers the crushing grinding and associated equipment to ensure adequate feeding in quantity and quality to the milling plant. There are two basic types of ball grinding systems open circuit and closed circuit. In the open circuit system the mill product has the fineness required for the next stage of the process. 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

Autogenous grinding or semi-autogenous grinding mills can be operated in open or closed circuit. However even in open circuit a coarse classifier such as a trommel attached to the mill or a vibrating screen can be used. The oversize material is recycled either externally or internally. The advantage of closed circuit system is eliminating over grinding phenomenon and reducing temperature of grinding chamber. Then the grinding efficiency and capacity is improved. In general the capacity can be improved by 10 -20 compared with cement mill when these specifications are similar. And capacity can be improved by 30 when grinding
