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 primarily used equipment in crushing arejaw crushers gyratory crushers and cone crushers whereas rod mills and ball mills closed circuited with a classifier unit are generally employed for grinding purposes in a mineral processing plant crushing is a dry process whereas grinding is generally performed wet and hence is more energy.

This is important as if you have not seen if yourself you can not trust it is really 10mm there should be no scats at 10 mm unless you are using much too small a grinding ball or the mill charge is much too low for example i was told by a client his ball mill feed was p80 9mm but when i went to look at the feed belt i saw this below.
