Cement The cement-making process, from crushing and grinding of raw materials, through roasting of the ground and mixed ingredients, to final cooling and storing of the finished product.

After the clinker emerges from the rotary kiln as small nodules, it is directed into coolers. Within these cooling units, the heat from the clinker is transferred to incoming air, which effectively lowers the temperature of the product. Once cooled, the clinker can either be stored in stockpiles for future use or immediately ground into cement.1
