2) Ball milling a ball mill with a diameter of 2.44 meters, inside new liners, grinding wet in open circuit. When the grinding conditions differ from these specified conditions, efficiency factors have to be used in conjunction with equation 1.

You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell C model or equation to get the RPM that corresponds to 75% for that mill diameter.

equation for ball mill circuits. Define and calculate the classification system efficiency of a ball mill circuit. Define and calculate the grinding efficiency of the ball mill in a ball mill circuit. Relate overall ball mill circuit output and circuit efficiency to specific design and operating variables.

The basic parameters used in ball mill design , rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum chunk size, product size as P80 and maximum and finally the type of circuit open/closed ...
