Rod Mill Design Calculations Mineral Processing &

If the rod mill feed will consistently be the same size, such as produced with closed circuit crushing, do not apply a rod mill inefficiency factor. The mill diameter, low or high ratio of reduction, and oversize feed factors should be applied to the calculated grinding power. EF1 Dry Grinding. EF2 Open Circuit Ball Milling.

Ball Mills Mineral Processing & Metallurgy

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
