· Visit these pages to get an overview of the cement production process, which begins with the extraction of limestone and clay from the quarry. The material is then blended, crushed and fed to the kiln. Postkiln, the clinker is cooled and goes through a final grinding method before it is ready to ship. Portland cement, the most common type of cement, is formulated in a variety of strengths and ...

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. The lime and silica provide the main strength of the cement, while ...

The manufacturing process known as the dry process is the most widely used at present. This consists of grinding the individual raw materials and feeding at controlled amounts into a rotary kiln and burning until they fuse into small lumps or balls called clinkers. In the wet process, a slurry of the blend is fed into the rotary kiln. The clinkers are cooled and then ground in two operations ...
