Clinker is the intermediate product used in the manufacturing of cement. There are two primary processes used to manufacture clinker: the dry process and the wet process. Our plants use the dry process, which is more energy efficient. In the wet process, the raw materials are mixed with water to form slurry, which is fed into a kiln.
