Summary of production process Cement is typically made from limestone and clay or shale These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions This blended raw material is called the raw feed or kiln feed and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C In its simplest form the
