Ball mills (Fig 1.1) are coming in cement plant areas of raw grinding, coal grinding and cement grinding which in turn as raw mill, coal mill and cement mill. Ball mills are horizontal tube mills having single or two compartments for grinding, Balls as.
The cement grinding plant acts as an individual production line in the last period of the cement production process. In the finished product period, the cement clinker is ground by adding moderate mixing materials and then forms the finished cement. Grinding Equipment System mainly includes tube mill (including ball mill and coal mill), roller.
