Optimization of Cement Grinding Operation in Ball Mills

The residence time of the cement particles inside the mill was shortened by adding the GA to the circuit. On the one hand, the shortening of the residence time provided a great advantage in efficient use of energy by preventing the overgrinding, while on the other hand, it caused some particles to leave the mill coarser than the expected size due to the reduced number of collisions with balls.

Energy consumption and output Cement mills are normally driven by electric motors. Modern installations draw power of 2-10 MW. The power (in kW) required to turn a ball mill is approximated by: P = 0.285 d (1.073-j) m n where d is the internal diameter in metres, j is the fraction of the mill volume occupied by media, m is the total mass of media in the mill, in tonnes, and n is the mill speed ...
