Predictive Control of a Closed Grinding Circuit System in
in the cement grinding circuit are: G20 is the ball mill; G24 is the dust collector of the ball mill; G31 is the bucket elevator; G35 is the centrifugal separator; and G39 is the dust collector of the separator. The grinding circuit is operated from a control panel through a SCADA system. The operators manipulate four variables: Fresh feedThis latter task can be solved by a conventional mill control system will be shown at the cement grinding later. The chemical composition control of the raw meal is necessary, because the relative amounts of C2S, C3S, C3A and C4AF formed in the kiln strongly depend on the oxide composition of the ground mix.Control in Cement Production ScienceDirect

Modeling and Optimization of Cement Raw Materials
This paper focuses on modelling and solving the ingredient ratio optimization problem in cement raw material blending process. A general nonlinear time-varying (G-NLTV) model is established for cement raw material blending process via considering chemical composition, feed flow fluctuation, and various craft and production constraints. Different objective The power ingesting of a grinding process is 50-60% in the cement production power consumption. The Vertical Roller Mill (VRM) reduces the power consumption for cement grinding approximately 30-40% associated with other grinding mills. The process variables in cement grinding process using VRM are strongly nonlinear and having large time delay PROCESS CONTROL FOR CEMENT GRINDING IN VERTICAL ROLLER MILL
