This is to certify that the thesis titled Robust Model Predictive control of Cement Mill circuits, submitted by GuruPrasath, to the National Institute of ecThnology, Tiruchirappalli, for the award of the degree of Doctor of Phi-losophy, is a bona de record of the research work carried out by .
This thesis describes the simulation of a raw grinding system in a cement plant by using a computer and boolean logic. The composite work includes discussion of two dif- ferent grinding systems; namely, a ball mill and a roller mill. In practice, operation is carried out either from a central control console or from a local panel. Three modes

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
