20090283237 | Rotary Drum and vibratory conveyor system - A rotary drum and vibratory conveyor system including a single walled rotary drum positioned above a vibratory conveyor assembly. The rotary drum may be segmented with each segment having end flanges that are connected to an adjoining segment with bolts. A section or sections of the rotary drum have perforations covered by a dust hood that allow sand and media to fall from the drum through a funnel structure onto the conveyor assembly. The vibratory conveyor assembly includes upper and lower conveyors, where the upper conveyor collects the media falling from the drum and passes the sand to the lower conveyor. The media may be redirected back to the drum inlet to be reused. | 11-19-2009 |
