Closed circuit ball mill – Basics revisited - ScienceDirect

Apr 01, 2013  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

Based on experience acquired over the years and the investigative work conducted by F.C. Bond, it was established that the optimum circulating load for a closed ball mill – cyclone circuit is around 250%. This value is used as guideline for the design of new circuits

It can be observed that for a ball mill circuit closed with cyclones, circuit relative capacity is not expected to increase significantly by increasing circulating load from 250% to 600%. This is because of the reduction in classification efficiency from 50% to 30% as calculated by Eq. (11). Compared to the ''reference point'', a ball mill ...
