Read MoreIn the discharge end of this mill, a slotted full diameter or partial diameter grate with discharge lifter assembly conveys the material to the discharge trunnion opening. The grate serves to retain balls, tramp, and coarse material. A gradient created between the feed opening and the discharge slots eases the flow of material. Feb 08, 2017 The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed ...

Read MoreDec 10, 2004 The ball mill is equipped with a classifying lining with a conical undulated shape. The absolute lifting height is quite similar to an industrial used liner plate. The discharge diaphragm is of the slotted type. The ball charge grading used during most of the test runs was an industrial standard grading with balls between 12 and 20 mm. Jul 01, 2003 Discharge grates play an important role in determining the performance of autogenous, semi-autogenous and grate discharge ball mills. The flow capacity (grinding capacity) of these mills is strongly influenced by the discharge grate designopen area and position of apertures, as well as the performance of the pulp lifters.
