Cement mill also called cement grinding mill, is a cement grinding machine used in cement plant for raw materials, cement clinker, and coal grinding. The cement mill produced by AGICO can be divided into the raw mill, cement grinding mill and coal mill.
The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.
Cement grinding unit, or called cement grinding plant, cement grinding station is an individual step in the cement production line. In the grinding plant, the cement clinker is added with the proper amount of mixed materials for grinding to produce finished cement. The newtype cement grinding units adopt pregrinding technology.
