During the last decade, semi-finish-grinding plants have been used more and more for the energy efficient grinding of high-quality cement. In 1999, it was found that by decreasing the ball charge filling ratio it was possible to lower the specific energy demand for grinding significantly.
Combi-grinding In semi-finish-grinding, the use of the POLYCOM® leads to energy savings of up to 40 % compared to conventional ball mill grinding systems. In existing plants, the throughput can be increased by over 100 %. In new combi-grinding systems, series-connected ball mills can have correspondingly smaller sizes than usual.
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.
