The critical speed of the mill, c, is defined as the speed at which a single ball will just remain against the wall for a full cycle The effect of varying mill speed on the power drawn by the mill is shown graphically in Figure 8 4 45% of mill volume and rod bulk densities range from about 5400 kg m3 to 6400 kg m3The first factor is the speed of rotation while operating the ball mill. At high angular velocities, the balls are thrown onto the mill wall by centrifugal force and no size reduction occurs. At low angular velocities, the balls move with drum until the gravity force exceeds the frictional force of the bed on the drum, then it will slide back ...

Drum Mill TM 300. The TM 300 Drum Mill is used for the preparation of granules and powders. The grinding process is performed either in dry or wet conditions. The drum mill can be operated either as a Ball or as a Rod Mill by using the corresponding module. A sufficient number of balls or rods is required for an effective grinding process.8.3.2.2 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.
