Abstract:

A cyclone-type processor has a vortex initiator positioned thereabove and an exhaust sleeve extending through the initiator and into the processor. A blower connects to the initiator chamber by a duct having a divider wall that separates the duct into an air-only channel and an entrained material channel. A feed inlet feeds material to be processed into the air flow of the entrained channel. The vortex initiator includes an outer annular chamber and an inner annular chamber open to the cyclone processor and is engaged by the duct to convey air into the outer chamber and air entrained material into the inner chamber. The inner and outer chambers and slots therebetween cooperate to cause the air flow to form a vortex and to urge entrained material away from the inner wall. The system may include additional cyclone stages for further material treatment.
