Sinogomine Industrial Technology Co.,Ltd-Ball mill machine price
Ball Mill Working Principle: Add balls into the ball drum to approximately 33%. As the ball mill rotates, the balls 'stick' to the inner surface of the ball drum due to the centrifugal force and are lifted on the rising side. At a certain angle, balls cascade down to the centerline of the ball mill because gravity overcomes the centrifugal force.
