Cement Extraction and processing | Britannica

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).

Energy Efficiency and Saving in the Cement Industry

Cement accounts for 83% of total energy use in the production of non-metallic minerals and 94% of CO 2 emissions. Energy represents 20% to 40% of the total cost of cement production. The production of cement clinker from limestone and chalk by heating limestone to temperatures above 950°C is the main energy consuming process.
