A system for handling a bulk particulate material generally consisting of a vessel for holding a mass of such material; a first elongated tube formed of a gas permeable material, having an inlet communicating with such vessel; a second elongated tube formed of a gas impervious material encompassing the first tube and spaced therefrom about the periphery of the first tube; a plurality of transversely disposed, longitudinally spaced partitions disposed between said first and second tubes, forming a plurality of isolated chambers encompassing the first tube; each of such isolated chambers having means for selectively introducing a fluidizing gas therein independently of the other of such chambers, at variable volumes and pressures whereby the volume and pressure of fluidizing gas diffused through the first tube may be modulated along the length thereof; and means for injecting a flow inducing gas into the first tube.

406 91, 406 95

A system for pneumatically conveying bulk particulate materials generally consisting of a material transport line including a first conduit formed of a gas permeable material providing a material flow passageway having an inlet and an outlet, a second conduit formed of a gas impermeable material, encompassing and spaced from the first conduit, and a plurality of partition walls disposed between the conduits and spaced along the lengths thereof, defining a plurality of plenums; a nozzle connectable to a source of gas under pressure, inserted into the passageway for injecting gas under pressure therein to impel material disposed in the passageway toward the outlet thereof; a main gas supply line connectable to a source of gas under pressure having branch lines each communicable with a plenum; and each of the branch lines having a pressure regulating means.
