Step 2: raw grinding and burning. Very fine grinding produces a fine powder, known as raw meal, which is preheated and then sent to the kiln. The material is heated to 1,500°C before being suddenly and dramatically cooled by bursts of air. This produces clinker, the basic material required for the production of all cements.
