However because of process complexity, accurate modeling of a cement mill is a difficult task. The product particle size in a cement mill is a non-linear function of the mill inputs [22]. Neural network based modeling and control strategies for product flow rate and mill load in the ball mill based cement grinding process have been developed [22].
