A cement manufacturing process is well suited for co-processing of wastes from different sources. Wastes need to be converted into alternative fuels and raw materials (AFRs) through the pre-processing operation and then utilized to substitute fossil fuels and raw materials used in the cement process. For environmentally sound co …

How cement is made. 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 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken …
