Abstract
Apparatus (10) for separating intermixed particulate materials. The apparatus (10) includes a housing (12) having a coaxial core (14) disposed therewithin to define an annular space (24) between the core (14) and the wall of the housing (12). A recirculator (46) is provided to provide gas to the housing (12) for cyclonic flow within the annular space (24). The intermixed particulate materials are introduced into the housing (12) and permitted to fall, under the influence of gravity, into the annular space (24) where separation is effected by interaction of the upwardly spiralling gas with the downwardly-passing, intermixed particulate materials.
