Optimization of Cement Grinding Operation in Ball Mills

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 coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding chamber.

MODULE #5 FUNCTIONAL PERFOMANCE OF BALL MILLING

In a ball mill circuit the "output" can be defined as the production rate of fines of the circuit. As for any output ball mill circuit output is a function of both its inputs and efficiencies. There are two "inputs" to a ball mill circuit the ore fed to the circuit and the power delivered by the grinding mill.
