Effects of grinding aid dosage on circuit performance and cement
For this purpose, influences of 250, 350 and 450 g/t of dosages of an amin-based commercial GA on the cement grinding circuit was compared with the condition in which GA was not used. The effects of GA dosage on the ball mill and air classifier were examined in detail considering the change in the residence time of the material.

Process Training Ball Mill
Ball mills for cement grinding usually operate with a filling degree between 25 and 35 %. The filling degree is defined as the volume of the grinding media (balls) as a percentage of the total mill volume. Since mill speed, liner shape and mill diameter are usually unchangeable parameters, the only adjustment in a mill can be made with filling ...
