Ball mill grinding plate - has lifting interval of 200 pi or more releasing ball from rib onto point well covered by balls and material for grinding

摘要

A rotating grinding plate shape ensures that the ball, after being released by the rib of the plate, drops on a point well covered by other balls and the material to be ground. During the rotation of the drum fitted with grinding plates the ball is released by the grinding plate rib after it has travelled an angular distance of alfa enclosed by the horizontal and a line through the centre of the ball in the release position. The angle gamma is the impact angle enclosed by the vertical and the drum radius through the centre of the ball after it has travelled along a trajectory from the release position. The angle epsilon represents the angular travel of the ball from the impact to the release position.
