Get Price8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight
Jun 19, 2015 A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula. The mill speed is typically defined as the percent of the Theoretical
Get PriceThe impact velocity of the balls relative to the vial walls is determined from the indent size. A model correlating velocities with indent radius is described. Velocities were determined for the Spex mill ( 1.8-3.3 m s- l) and for a new high capacity mill (2.6-3.8 m s - l) and were found to be strongly dependent on ball
