Abstract

Apparatus for conditioning a granular material having a centrifugal throwing wheel for projecting the material radially against an impact surface member which completely surrounds and is spaced from the periphery of the wheel and includes an impact plate and ricochet plates. The impact plate is provided with generally radially disposed baffles with sides of adjacent baffles guiding and channeling the stream of material. The baffles are triangular in cross section with a forwardly facing side sloping at a lesser angle than the other side. The general course of granular material is downwardly through the apparatus and to retard this flow and thereby promote separation of granular material from fines, bed baffles which entrap and hold granular material are provided within the apparatus. Apparatus is provided for introducing a stream of air into the apparatus for transverse flow across the retarded downward stream of granulated material to effect separation of fines.
