Closed circuit ball mill – Basics revisited - ScienceDirect
2013-4-1 · The reference point is a conventional ball mill circuit in closed circuit with cyclones operating at 250% circulating load and having 38% of fine material reporting to cyclone underflow, resulting in a classification efficiency of 50%. This efficiency was chosen as an industrial practice “average” from the data presented in Fig. 6.

Closed circuit ball mill – Basics revisited - ScienceDirect
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).
