There are four stages in the manufacture of portland cement: (1) crushing and grinding the raw materials, (2) blending the materials in the correct proportions, (3) burning the prepared mix in a kiln, and (4) grinding the burned product, known as " clinker," together with some 5 percent of gypsum (to control the time of set of the cement).

The model was used to study the influence of SRF co-firing in the kiln. It was found that increased shares of SRF, reduced flame and bed temperatures, which caused an increased free lime content in the clinker, indicating a decrease in clinker quality. These effects could to some extent be avoided by increasing the energy input to the kiln.
