The pulverization of coal is performed in the coal mill, while the hot flue gasses from PH (Hfg 4) are used for preheating and drying of the raw coal. The stream of preheated coal (Fl ph) is then transferred into the rotary kiln burner. A planetary clinker cooler (CC) is used to cool down the clinker from approximately 1400°C to 100°C.
