Closed circuit ball mill Basics revisited ScienceDirect

2013-4-1  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).

Ball Mill an overview ScienceDirect Topics

The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones. The cyclones send correct-size material on to flotation and direct oversize material back to the ball mill for further grinding. The ball mill is a tumbling mill that uses steel balls as the grinding media. 3.1 Introduction
