The ground coal is picked up by an air stream emerging the mill through a port ring on the periphery of the grinding table. Air entering through the port ring creates a fluidizing zone in which "heavy material" (mill rejects—MR) such as rock falls through the port ring into the air plenum below the grinding table and is ejected from the ...

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.
