Closed circuit ball mill – Basics revisited - ScienceDirect
01-04-2013· 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).
Closed Circuit Grinding VS Open Circuit Grinding
For a closed circuit ball mill flowsheet as represented in Figure 2, a simplified relationship (Equation 1) for relative capacity at different circulating load and classification efficiencies was,
