Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silicabearing minerals to form a mixture of calcium 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.
cement mill operations in four ways: • More consistent quality (grade). The continual monitoring of the mill loading and the adjustment of the feed and separator results in reduced variations in cement grade. This has the added benefit of a more consistent product quality. The control strategy is designed to respond to disturbances in the
