High efficiency ball mill for cement grinding News Date 2015-12-08 10 14 49. High efficiency cement ball mill is mainly used in grinding raw materials and final products in cement plant. It is also suitable for grinding various ores and other materials in chemical, metallurgy, and power industry and so on.
View AllThe disadvantages of ball mills include their considerable metal consumption and deterioration grinding media, as well as a lot of noise. Most of the energy useless lost during ball mill operation, leading to low it efficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by using mill.
