The temperature of the gas coming into the raw meal department via the hot gas fan depends on the type of raw material being processed. Typically, the hot gas temperature at the inlet to the raw meal department is 180 °C for the STD ("standard") type and 260 °C for the HS ("high strength") type.The gas flow rate is around 300 kN m 3 /h during normal operation.

Cement Separator. Cement separator, also called cement mill separator, is the necessary equipment in the powder classifying system of cement, chemical, mineral, and other industries. It can respectively collect the qualified fine powder and coarse powder from the airflow after they are ground by the grinding equipment to a certain extent.
