Multivariable Nonlinear Predictive Control of Cement Mills

load contributes to fast wear of the mill internal equipment. Moreover, the energy consumption of the mill (i.e., the ratio energy per unit product) depends on the output of the mill that is related to the load in the mill. A usual approach is to control the tailings flow rate by using the feed flow rate as control input.

Throughput optimisation in milling circuits

A Model Predictive Control System such as MillStar Advanced Process Control (APC) can continuously seek the optimum mill operation by changing the solids feed or load setpoint, e.g. by continuously determining whether the mill is overloaded or under-loaded. Safety controllers can be used to change the solids feed rate and feed water to prevent
