FL ball mill for cement grinding
The ball charge mill consists of grinding media in various sizes to ensure optimum grinding efficiency and easy maintenance. The size distribution of the grinding media in the coarse grinding compartment is designed to just crush the coarsest particles in the mill feed material and to ensure adequate fineness of the material passing the diaphragm.

The profiling of the shell lining plates creates the movement of the ball charge, which causes the grinding of the material. It is therefore essential for effective grinding in the mill and far more than just a wear part. The exact profile shape has to be defined depending on the ball sizes used, the rotation pace and the mill diameter.
