The Cement Production Process

The three broad processes of cement manufacturing are: Raw milling — the preparation of the kiln feed. Calcining and burning or clinkering — the conversion process that takes place within the cement kiln and associated equipment. Finish milling — the grinding of clinker to produce cement.

Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth's sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the is either limestone or dolomite.

Emissions from the Cement Industry

May 09, 2012· The direct emissions of cement occur through a chemical process called calcination. Calcination occurs when limestone, which is made of calcium carbonate, is heated, breaking down into calcium oxide and CO2. This process accounts for ~50 percent of all emissions from cement production.

The Manufacture of Portland Cement

The cement manufacturing process involves four distinct stages, and these are outlined below. Step 1 Quarrying The raw material for cement manufacture is a rock mixture which is about 80% limestone (which is rich in CaCO3) and 20% clay or shale (a source of silica, alumina and Fe2O3). These are quarried and stored separately.
