automation and optimization of coal grinding by means of ball millsAbstract: This paper deals with the system of automated control and optimization of coal grinding by means of ball mills at thermoelectric power stations. The system provides continuous monitoring of grinding, ventilating and drying capacity and it optimizes the mill performance in order to ensure maximum possible grinding.capacity of ball mill for coal,energy calculation model of ball kinematics based on ball mill coal .friction between the ball and the mill, the ball and the coal contributes to the grinding capacity. Enlarging the mill's loading capacity can increase the percentage of the kinetic energy in balls' total energy. However, when the loading capacity is excessive, it also can limit the ball's motion and reduce the ball's kinetic energy.
