Operation and Elements of a Closed Circuit Ball Mill System. Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media and lined with lifting liners. The first chamber coarsegrinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.
Ball mills are the most common grinding machine employed in the mining industry. ... ClosedCircuit or OpenCircuit. Ball mills may operate in a closedcircuit, or opencircuit. Closed circuits return a certain amount of the ball mill's output back to the ball mill for further size reduction. A typical closed system grinds the ore between two to three times. Hydrocyclones installed directly ...
