interruption of the cement mill grinding process. The load in the mill must be controlled at a well chosen level because too high a level of the load in the mill leads to the obstruction of the mill, while too low a circulating load contributes to fast wear of the internal equipment of the mill. Moreover, the energy consumption of the mill ( ...
