The drive motor constantly rotating cylinder, the cylinder body crushed ore and a planetary ball mill at the cylinder rotation by friction and centrifugal force was taken by a certain height after deceleration device lining due to gravity, they produce Paola state, diarrhea off state, under the impact of the ore and grinding non-stop action, and gradually be crushed. was crushed by a planetary ball mill ore discharge section discharge spout. discharge of minerals spiral classifier in classification of qualified products by the lead after , grit feeder through joint and back within a planetary ball mill to continue grinding. feeder continuing to feed a continuous and uniform, continuous ore joint feeder evenly into a planetary ball mill, grated material stream continuously discharged from the ceramic planetary ball mill ceramic planetary ball mill is grinding equipment can work 24 hours a day.
