Feeder. The AutoCharge feeder continuously charges balls from the storage bin to the mill. The feed wheel picks up balls in each flight and when they pass the top-centre of the wheel, they roll off into either the counting chutes or the weighing module before dropping directly into the mill feed stream.
Ball mill drums offer an efficient and inexpensive way to grind materials down to a more usable size, often as fine as 25-75 microns. Both continuous and batch style ball mills use centrifugal force, gravity and hard media to break up industrial materials into fine pieces or powder. Ball milling systems grind dry material and wet slurry alike.
The main role of steel balls for ball mills is to impact and crush the material, and also play a certain grinding role. ... it is evenly sent to the ball mill through the elevator and feeder, and the ball mill crushes and grinds the ore.
