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.

2006-12-1  Plitt and Nageswararao models have been used to describe the performance of hydrocyclones, which by linking to the ball mill model allow for closed-circuit simulations. To describe material flow through the ball mills, two tanks-in-series models called Weller’s model and one plug flow unit plus n perfect mixers units (1PF + n PM) model have been used.
