Nov 14, 2012· The rotary speed of ball mill directly determines the state of motion of the cylinder body of the grinding media and grinding operations effects. The lifting height of the balls in the ball mill is small when the speed is low. Because the gravity of the balls themselves, balls fall from the top as spilling off the state.
2 Operating Speed A ball mill grinds material by rotating a cylinder with steel grinding balls, causing the balls to fall back into the cylinder and onto the material to be ground. The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the mill. The larger the diameter, the slower the rotation. If the
