摘要： The invention is a cyclone-type particle classifier. It comprises an upper body section, with an inlet for a particle laden gas, and a lower conical section where classification occurs. The lower section comprises an inner foraminous portion and a coaxial outer solid walled portion. These are separated so as to define an annular-shaped volume between them. The two lower sections are further separated at their upper basal portion by an air gap which is in communication with the annular volume and the ambient atmosphere. The annular space is connected to one outlet duct at its apex while the inner volume of the foraminous portion is connected to another duct. These ducts lead to the suction side of appropriate fans. The two ducts serve as the only gas outlet means from the device.
