Jun 25, 2018· Mill effective diameter = m . 335 is a constant used for dry grinding with steel balls in the mill. Actual size of media is taken is lower than the calculated value. It is around 80 to 90 mm. If you Wants to reduce the maximum ball size, thenreduce the feed size by using pregrinding operation.
Oct 19, 2017· It uses to help determine the grinding media optimal size must be loaded into the ball mill for proper operation ensure. The calculation formula is below: B – the grinding balls diameter, mm; A – the correction factor (for grinding balls A = 20,17; for cilpence A = 18,15); F – the feedstock grain size in 80% of the material, μm;
Charge Height. Generally : For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He,...
Motor Sizing Calculations. There are three factors to calculate when sizing a motor; Moment of Inertia, Torque, and Speed. Moment of Inertia. Moment of inertia is the measure of an object's resistance to changes in its rotation rate. When an object is just sitting without any motion, the moment of inertia is 0.
