Abstract
Abstract A combined vane-rotor separator comprises a rotor, which has upstanding illor baffle rails arranged at the outer periphery thereof. A housing surrounds the rotor to which a feed mixture is supplied in a gas flow from a roll mill and from which the gas and fines leave through a draw-off duct. A cone is located below the rotor and is attached to the housing. A series of guide vanes arranged in a ring is located between the housing and the cone and serves as a guide for the gas flow from the roll mill.
