The power calculated on using equation 1, (Bond, 1961; Rowland and Kjos, 1978), relates to: 1) Rod milling – a rod mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit. 2) Ball milling – a ball mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit.

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 operations remove material by feeding a workpiece into a rotating cutting tool with sharp teeth, such as an end mill or face mill. Calculations use the desired tool diameter, number of teeth, cutting speed, and cutting feed, which should be chosen based on the specific cutting conditions, including the workpiece material and tool material.
