Cement production is a complex process that begins in the raw mill, where limestone and other materials are pulverized and mixed. In the kiln, the raw materials are subjected to high temperatures and transformed to clinker. Clinker is transferred to the finishing mill, where it is ground and mixed with gypsum to produce the final product.
