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).

Innovations in Cement Production

INNOVATIONS BY LAFARGE HELP IRAQI CITY TAKE OUT THE TRASH WHILE TAKING SOME OF THE CARBON OUT OF CEMENT PRODUCTION. Cement — the key ingredient of concrete — is the world’s most widely used building material.

Cement and Concrete: Environmental Considerations

Cement production is one of the most energy intensive of all industrial manufacturing processes. Including direct fuel use for mining and transporting raw materials, cement production takes about six million Btus for every ton of cement (Table 2). The average fuel mix for cement production in the United States is shown in Table 3.

Portland Cement Manufacturing Industry: National Emission

Portland cement manufacturing is an energy intensive process in which cement is made by grinding and heating a mixture of raw materials such as limestone, clay, sand, and iron ore in a rotary kiln. The kiln is a large furnace that is fueled by coal, oil, gas, coke and/or various waste materials.
