To produce cement, the raw meal is burned to clinker in a long rotary kiln. After leaving the rotary kiln, the clinker has a temperature of up to 1300 C and must be cooled down to a temperature of about 200 C for further storage. To achieve this, the clinker bed is cooled with a continuous stream of air. Pressure
