### Effects of grinding aids on model parameters of a cement

The impacts of the grinding aids on the ball mill are mathematically expressed using the obtained data from industrial tests. The particles at a certain size in the mill are formed by both particles at that size present in feed and the particles that are broken from coarser size to that size.
