Separators in the cement industry
Often, there are a primary air inlet, a second air inlet and also a tertiary air inlet depending of the design. The airflow leaves the guide vanes almost tangentially to the outside of the cage. Material is arriving in the separation zone between the guide vanes (or louvres) and the rotating cage.
