During the screening process, the equipment will not vibrate, but generally, the motor and reducer drive the drum to rotate through the bearing. The material in the drum passes through the screen from high to low due to the rotation of the drum. And it is successfully screened out, so the trommel screen belongs to a type of rolling screening. 2.

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.

The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower. For a finer feed, the 20 mm + 10 mm binary mix is able to break the feed at a faster rate. Download : Download highres image (344KB)

Principle of Ball Mill: The size reduction in the ball mill is a result of fragmentation mechanisms (impact and attrition) as the balls drop from near the top of the shell. Mixing of feed is achieved by the high energy impact of balls. The energy levels of balls are as high as 12 times the gravitational acceleration.
