The entire mill feed enters the drum via a chute or spout and an internal spiral carries the feed into the trunnion liner. The drum feeder may be used in lieu of a spout feeder when headroom limits direct spouting. The drum also provides a convenient method of adding grinding balls to a ball mill. The drum is generally lined with Manganese Steel.

All Grinding Mill & Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.

The API diesel fuel with energy output of 990 kw-hrs. The engine consumed 12.15 kg of fuel per hour with a heating mechanical efficiency of the engine is 92%. Assume a drum of value of 45,130 kJ/kg and 137.4 kg of air at 15.5ºC per hour. fuel …

Hammer mills, unlike ball and rod mills, act to shred mining ore rather than grind it. A hammer mill consists of a steel drum with a vertical or horizontal rotating shaft on which hammers are mounted. The hammers will swing freely from a fixed point on the central rotor and when material is fed into the mill the rotor is spun at a high speed so ...

Steel balls of different sizes may have uneven axial distribution in the rotating drum, which will cause different crushing effects in different areas of the ball mill.

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 …
