Abstract

A rotor assembly includes a shaft and a plurality of radially outwardly extending vanes surrounded by a circular cylinder. A truncated conical segment screen is in each compartment formed by the vanes dividing each compartment into inner and outer subcompartments. Apertured top and bottom face plates are respectively above and below the vanes. A housing includes top and a bottom plates to which the rotor assembly shaft is rotatably secured. A material inlet hose and dust exhaust pipe are attached to the top plate and are in simultaneous successive fluid communication with each outer and inner subcompartments respectively as they rotate. A discharge port is in the bottom plate for discharging separated material in an outer subcompartment downstream from the outer subcompartment then receiving material from the inlet hose. The top and bottom plates are spaced a small gap from the rotor face plates to provide fluid seals therebetween to fluid isolate the compartments from each other.
