Power saving measures for cement mills

01 Measures to reduce power consumption from a process perspective (1) The design and selection of the mill is a key factor In general, replacing a small mill with a large mill can increase production and save electricity, and replace the ball mill with low efficiency with a high-efficiency pulverizer. It can also receive significant energy-saving effects such as vertical grinding, roll

Scale‐up of power consumption in agitated ball mills

Previous investigations have shown that the specific energy input is the overall parameter of influence on product size during communition in agitated ball mills, from laboratory up to industrial scale. The specific energy input is the introduced energy related to the amount of comminuted material. This parameter can be used for mill scale‐up.
