tation of the whole cement manufacturing process. Raw materials sis burned to produce clinker. The clinker is cooled down with air in a grate cooler and then stored in the clinker silo. Additives such as gypsum and limestone are added to the clinker before being milled in the cement mills to the final cement product.
