The Cement Manufacturing Process Thermo Fisher ScientificManufacturing process Lafarge in South Africa Cement

Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay to a fine powder called raw meal which is then heated to a sintering temperature as high as 176 C in a cement kiln In this process the chemical bonds of the raw materials are broken down and then they are recombined into new compounds The result is called From the limestone quarry to the delivery of the end product follow every step in the cement manufacturing process Step 1 extraction of raw materials The raw materials needed to produce cement calcium carbonate silica alumina and iron ore are generally extracted from limestone rock chalk clayey schist or clay
