Model predictive control of a rotary cement kiln
Preheater kiln for the cement clinker production with four cyclone stages in the preheater tower, the rotary kiln and the cooler. Usually, at this stage in modern kilns a precalciner is introduced. Essentially, a precalciner is an additional combustion chamber, which is able to drive the dominant endothermic process of calcination.

The advent of the rotary kiln is closely tied to the creation of Portland cement. In 1824, Joseph Aspdin successfully produced an eminently hydraulic lime by cooking at high temperature, in a bottle kiln, a mixture of limestone and clays; he referred to his output as "Portland Cement" [2], [3], [4].
