Applicant: The University of Toronto, Innovations Foundation Inventor: Professor Bernard Etkin, Title: PARTICLE CLASSIFIER ABSTRACT, A particle classifier has a uniform laminar, classifying air stream and a duct to introduce particulate material generally perpendicular to the air stream. The particulate material is entrained in a secondary air stream that is diverted as it enters the classifying air stream by a curved surface. The curved surface produces and diverts the air stream by the Coanda effect to minimise disturbance to the classifying air and segregate the particles from the secondary air.
