seen the vertical mill consistently presented lower net specific energy consumption than the ball mills which operate on the same circuit. The averages were 11.3 11.7 and 6.5 kWht respectively for ball mill 01 ball mill 02 and vertical mill. Figure 5 – Net specific energy consumption of regrinding circuit.
Read MoreThe 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.
