Step 2: clinker sintering. Clinker sintering is a crucial link in clinker calcination, which mainly occurs in the cement kiln. Inside the kiln, raw meals are heated by rising temperature and generate a series of physical and chemical reactions. When the temperature reaches its peak, the clinker will be produced by rapid cooling.
Details 
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.
