ABSTRACT:
A method and apparatus for communicating feed stock in the form of shreds or the like to form a low density particulate product. The shredded feed stock is fed to a material handling rotor that functions as a centrifugal blower. The apparatus includes a housing that defines a cylindrical rotor chamber formed about a horizontal axis and a volute-shaped internal passage having at least one convolution formed around the rotor chamber. Located within the housing is a cylindrical screen with perforations that open into the rotor chamber. The centrifugal blower rotor is mounted in the rotor chamber and has a plurality of radial vanes with rakers attached to the outer ends closely spaced from the inner surface of the screen so that they continuously wipe pass the perforations to prevent clogging or blinding.
