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.

Dry Grinding Coke Grinding - Mineral Processing

As grinding becomes finer Ball Mills are required and closed circuit operation is generally recommended. Air separators do the sizing work as shown in a typical circuit. In dry grinding work, principally fine grinding, size reduction is accomplished predominantly by attrition rather than impact.

Closed circuit ball mill – Basics revisited - ScienceDirect

01-04-2013  1. Introduction. Over the years, ball mill circuits closed with cyclones have become an industry standard, and since the early days, it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i.e. its capacity to produce the desired final product).

Grinding

The grinding effect is caused by the collision between the steel balls themselves and the collision friction between the steel balls and the material. The specifications, materials and usage of the steel balls will directly affect the work efficiency of the ball mill and even the entire production line of the concentrator, so it is valued by many mine owners.
