Sep 07, 2011· Re: VRM and ball mill circulating load I guess this could be measured as usually based on the particle size distribution (PSD) of the separator feed, product and rejects. Based on these three PSD curves, the circulating factor (load) might be evaluated as well as the separation curve.
The quality of contact is ball angle. With decreasing ball foot angles, at a constant filling linked to the compactness of the load. Further studies will be degree, the performance increases as indicated by a lower spe- required to correlate the ball load compactness with the mill cific energy (kWh/t).
