ABSTRACT:
The present invention teaches that air may be injected into the sloping bottom of a bulk dry particulate cargo container (micron-sized through quarry-sized dry particulate) accompanied by traditional conveyance-variety pneumatic air, causing the bulk dry particulate cargo to enter a bi-phase state having an air matrix with particulate inclusions. The result of this air lubrication is a dramatically reduced coefficient of friction. This bi-phase material may be extremely fluid, easily exiting a discharge port without regard to normal bulk dry particulate friction or angle of repose. The present invention also teaches a cargo container having a plurality of air injectors on the sloping bottom of a particulate plenum and having air supply apparatus feeding the air injectors.
