raw mill and rotary kiln energy and mass balance

2020-7-20  Simple input method (A1) and detailed input method (A2): The actual amount of raw meal consumed for clinker production can be determined by weighing the kiln feed and subtracting the Dust return This part of the kiln feed is not consumed for clinker production or to form bypass dust but is transported back by the gas flow (opposite direction to the mass flow) and (firstly) out of the preheater system. It is returned to the dust cycle, which often involves the raw mill
