The cement mill (or finish mill) presents a convincing case for automation as the optimization process employed by many cement manufacturers is mainly manual. Particle fineness of the cement is measured by way of Blaine measurements, routinely carried out separately offline. In a conventional setup, peak performance was ensured by manually ...

The product particle size in a cement mill is a nonlinear 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]. But there is no effort for prediction of particle size.
