The primary ball charge pattern and the design ball charge pattern that is introduced by KHD Company (Cement ball mill''s manufacture Company) are presented in Table 6. It can be observed in this table that the amount of current ball charge is about 14% less than the amount of design ball charge, so it could reduce the CBM''s efficiency.
Jul 31, 2014· Due to limitation of the mill''s rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (58 mm range) improves grinding energy efficiency up to 50% using stirred mills.
are too large to be fed into the tube (ball) mill. (5) Ground materials are dried by the flue gas from the kiln. Schematic process flow of vertical roller mill for grinding of raw materials Vertical roller mills are adopted in 20 cement plants (44 mills) in Japan. Results Table Energy saving effect of the vertical roller mill Ball mill
