Fans Fan power is linked to specific heat consumption and many operating parameters. Optimizing these parameters will help reduce the fans power consumption. Mills In the case of ball mills, optimizing the mill load and maintaining the internal parts of the mill will minimize energy consumption.
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.
