Cement mill Wikipedia

These have been used for many years for the less exacting rawmilling process, but recently roller mills, in combination with highefficiency separators, have been used for cement grinding. The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient. Energy consumption

Manufacturing process < All about Cement < Cement : Lafarge

The kiln is at the heart of the manufacturing process and in order to heat the materials, a 2,000°C flame is required. Once inside the kiln, the raw meal is heated to around 1,500°C. At this temperature, chemical reactions take place to form cement clinker. Upon exiting, the clinker is cooled and stored ready for grinding to

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.
