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. It’s also the product of an energy-intensive process that accounts for about five percent of global greenhouse gases driving ...
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.
Cement Manufacturing Enforcement Initiative | US EPA
The cement manufacturing industry was an EPA New Source Review/Prevention of Significant Deterioration (NSR/PSD) national enforcement initiative in fiscal years 2008-2010 and was continued as a Reducing Air Pollution from the Largest Sources national enforcement initiative for fiscal years 2011-2013.

the wet process. Certain solid waste products from other industries, such as pulverized fly ash (PFA) from power stations, Slag, roasted pyrite residues, and foundry sand can be used as additives in cement production. Waste Characteristics The generation of fine particulates is inherent in the process, but most are recovered and recycled.
