摘要： An aerodynamic recirculating separator of bulk materials that includes an air blower capable of forming an air stream, an outlet stream directing means, a separation chamber including two inlets and two outlets, a loading hopper, at least one discharge channel, a return air duct including a plurality of turning portions, and at least one residue collection chamber. An outlet of the air blower connects to the first inlet of the separation chamber, an outlet of the loading hopper connects to the second inlet of the separation chamber, the first outlet of the separation chamber connects to the return air duct, and the second outlet of the separation chamber connects to the at least one discharge channel. The air blower, the separation chamber, and the return air duct are consecutively connected so as to form a recirculation channel. The separator forms a material particle flow from the loading hopper to the separation chamber, to distribute commercial particles by their aerodynamic parameters in the separation chamber as the commercial particles fall from the loading hopper and are blown by the air stream formed by the air blower, and to remove the commercial particles through the at least one discharge channel. The separator forces remaining material particles into the at least one horizontally flared portion, directs at least a part of the remaining material particles into a residue collection chamber by way of gravity, and injects air into the separation chamber via the discharge channels. The first downstream horizontally flared portion includes a downwardly curved bottom wall and an opening in communication with said flared portion and the external environment. The opening is disposed in a smooth turn zone from said flared portion to the first of the plurality of turning portions, which has an upward turn.
