Soft Constrained MPC Applied to an Industrial Cement Mill

The key novelty in the MPC is that it uses soft constraints to form a piecewise quadratic penalty function with a dead zone. The MPC with this penalty function mitigates the control the cement mill grinding circuit (Prasath and Jørgensen, 2009b). The controller consists of an estimator and a regulator parameters

Enhancing the quality. The FCB TSV™ Classifier allows more accurate control of the particle size distribution so its installation provides the opportunity to target cement quality parameters and to set operating points with much tighter margins. Both result from the sharp classification of the patented turbine blade profile and from the proven air seal of the turbine preventing coarse

OPTIMIZING THE CONTROL SYSTEM OF CEMENT MILLING:

the control loops are of the PID type. As was clearly stated by Astrom (2000), model uncertainty and ro-bustness have been a central theme in the develop-ment of the field of automatic control. Therefore, for the model-based control of a CM, not only the values of the dynamic model parameters are necessary, but also their uncertainty. Austin et al.

Optimization of mill performance by using

Optimization of mill performance by using online ball and pulp measurements Soon after a stop, a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples. Crash stops are difficult to handle. The mill and all feed streams should be stopped simultaneously but, often, they are stopped around about the same time.

Cement kiln - Wikipedia

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

What does a cement plant of the future look like?

3) The cement mill grinds the clinkers to an appropriate heat to produce cement. Each step is critical but the final step is where the magic happens. Grinding to perfection. In the final step, the cement mill grinds the clinkers using horizontal ball mills. The ball mill has two rotating chambers with ceramic balls that grind the clinkers.
