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. Clinker grinding uses a lot of energy and the cement becomes ...

Closed Circuit Grinding VS Open Circuit Grinding

12/10/2016  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. This single-stage circuit is chiefly employed for coarse grinding when a product finer than 65 mesh is not required, but it can be adapted for fine grinding by substituting a bowl classifier for one of the straight type so as to ...

Cement Kilns: Size Reduction and Grinding

Closed-circuit grinding is used to remove fines from the milling system, so that the mill can function with a feed that is optimally coarse for its grinding action. In early grinding, both for cement and rawmix, sieves were originally used as the "separator". In the case of rawmix, if coarse quartz is avoided in the raw material, the critical ...
