Calculate and Select Ball Mill Ball Size for Optimum Grinding

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and

Milling

The Milling Process Definitions Cutting speed,v c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed, v e Indicates the surface speed at the effective diameter (DC ap).This value is necessary for determining the true cutting data at the actual depth of cut (a p).This is a particularly important value when using round insert cutters

“EXPERIENCE WITH SYNCHRONOUS AND

The torque speed characteristic of a typical ball mill is shown in Figure 1. On this curve there are three distinctive points of interest, which uniquely characterize the ball mill operation. Figure 1 a) The breakaway from rest is identified as the region on the graph requiring 40% to 70% of nominal torque from rest to approximately 20% speed.
