Abstract
A blast media transport and throwing wheel apparatus includes a throwing wheel in the form of a straight vane centrifugal fan with a conically shaped axial opening therein for receiving the blast media (e.g. pellets) to be propelled against molded article to be deflashed. A shroud surrounds the throwing wheel and includes an entrance opening aligned with the axial opening and an exit opening through which the media is propelled. A feed cage is mounted on the shroud and extends into the axial opening and a feed tube connects the feed cage with a hopper containing a static quantity of the media. The feed cage includes a passageway for directing the media into the throwing wheel on one side of the rotational axis thereof.
