The paper presents the design procedure of a modelbased control algorithm for the regulation of tailings and product flowrates in a cement mill. The control variables are the feeding rate and the classifier speed. Experimental results of a fullscale industrial application are reported and discussed with a view to the control of the fineness of the cement.
1 Over the past 15 years, minetomill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.

HOLTEC has undertaken Performance Optimisation of the cement grinding circuits by doing process diagnostic studies in many cement plants. The paper describes the approach for the process diagnostic study for the optimisation of a ball mill circuit and is supported with typical case study done by HOLTEC in a mio t/a cement plant.
Vertical roller mills (VRMs) have become the equipment of choice for raw and solid fuel grinding in cement factories. Increasingly modern cement plants also use VRMs for cement grinding. However, opportunities for the optimisation of VRMs are less obvious than with ball mills as all processes of grinding, drying, classification and regrinding ...
