Grate Ball Mill Introduction: There is a discharging grate plate installed at the discharging end, in the inner surface of the hollow shaft liner equipped with anti-spiral blades, it can overflow the ore pulp out of the ball and made the crude ore back to the mill. Typically, ball mill with cylinder diameter of 900-2100mm and motor power lower than 400kw adopts the high starting torque of Y series drive way and JR asynchronous motor drive way, in the middle connecting by reducer and coupling.
