Crushing, a form of comminution, one of the unit operations of mineral processing. In the field of extractive metallurgy, mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their ores .
Jan 20, 2019 Each ball mill is 5.0 m by 7.6 m, charged with 90 mm in diameter high chrome cast steel balls. The nominal grinding capacity of each mill is 200 t/h each. Typical ball consumption is 340 g/t. Blended ore from the stacker reclaimer is withdrawn through belt feeders below one of the 3,000 tonne ore silos that are interconnected.

Jun 19, 2015 The approximate horsepower HP of a mill can be calculated from the following equation: HP = (W) (C) (Sin a) (2π) (N)/ 33000. where: W = weight of charge C = distance of centre of gravity or charge from centre of mill in feet a = dynamic angle of repose of the charge N = mill speed in RPM. HP = A x B x C x L. Where. A = factor for diameter inside shell lining
Jun 19, 2015 Charge movement at Various Mill Critical Speed. The Formula derivation ends up as follow: Critical Speed is: N c =76.6(D 0.5) where: N c is the critical speed,in revolutions per minute, D is the mill effective inside diameter, in feet. Example: a mill measuring 11’0” diameter inside of new shell liners operates at 17.3 rpm. Critical speed is
Ball charge loading – impact on specific power consumption and capacity152 Кб. Past ball mill studies have evaluated the importance of many factors in ball mill grinding efficiency including ball size distribution, mill length to diameterThere are several methods of calculating the net mill power draw for an industrial mill.
8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure 8.3 Ad this can be used to establish the essential features of a model for mill power. The torque required to turn the mill is given by Torque T Mcgdc T f (8.9) Where Mc is the total mass of the charge in the mill and Tf is the torque required to overcome friction. Power 2 NT (8.10)
