Closed-circuit grinding - Glossary - Schenck Process

Closed-circuit grinding. 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.

Cement mill - Wikipedia

Closed-circuit systems. The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultra-fine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.

Optimization of Cement Grinding Operation in Ball Mills ...

Operation and Elements of a Closed Circuit Ball Mill System. Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.
