Air separation - Giesserei Lexikon

An aggregate operating on the basis of the counter flow principle which separates (screens) fines from granular materials using inertial forces (gravity separation) in the air. In this process, lighter particles are discharged and heavier particles are deposited in a collection tank. The separation rate is determined by the air flow volume.
