Closed Circuit Grinding VS Open Circuit Grinding

Closed circuit grinding consists of one or more mills discharging ground product to classifiers which in turn return the coarse product from the size separation back to the mill for further grinding. In this circuit, grinding efficiency is very dependent upon the size separation effected so care should be exercised in selecting the type and size of classifier used to close the system.

High-efficiency cement grinding - International Cement

This is called a combi-grinding circuit. The main feature of such a system is the pre-grinding of cement clinker in the POLYCOM and a final grinding in the ball mill. The specific power consumption compared to a ball mill cement grinding is significantly lower and additionally paired with a 30 to 40 per cent increase in output.

The cement mill - Understanding Cement

In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding. Gypsum is interground with the clinker in order to control the setting properties of the cement.

OPTIMIZING THE CONTROL SYSTEM OF CEMENT MILLING:

mostly performed in closed circuits: The ball cement mill (CM) is fed with raw materials. The milled product is fed via a recycle elevator to a dynamic separator. The high fineness stream of the separator constitutes the final circuit product, while the coarse material returns back to the CM to be ground again.
