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 minimize disturbance to the classifying air and segregate the particles from the secondary air.
