ABSTRACT:
A method and apparatus is disclosed for separating finely sized materials of diverse weights comprising a housing 8 having an opening 20 through which materials may be introduced for separation, an air intake 26 through which air may be introduced, and an air outlet 34 through which an air stream may exit. Means 53 are provided for forcing air into the housing 8 through the air intake 26 and out of said housing through the air outlet 34. A series of steps 10, 12, 14 is mounted within the housing 8 over which the materials may cascade. Means are further provided for channeling air introduced into the housing 8 through the air intake 26 into at least one air stream which passes between adjacent steps of the series of steps whereby the air stream may pass through the cascading materials and entrain the lighter materials.
