The document analyzes data from ball classification calculations for different ball mill lengths. It shows the number of pieces and total weight of balls categorized by diameter and how these values change as the ball mill length increases from 0.5 to 7.5 meters. As length increases, the percentage of larger diameter balls (70 and 60mm) decreases while the percentage of smaller …

Introduction The closed ball milling circuit is a key part of many minerals processing operations. Recirculating load is the fraction of mass flowing through the mill divided by the feed throughput, and this has been found to be a significant consideration in mill circuit performance, and thus the economics of the operation. This paper will describe a digital tool and methodology that can
