ABSTRACT:
An apparatus including: a conduit operably connected to a source and extending downwardly therefrom, the conduit being adapted to permit a flow of particulate material from the source through the conduit; a fluidizing nozzle operably connected to the conduit and extending downwardly therefrom, the nozzle defining an inlet for receiving material from the conduit and defining an outlet for dispensing material from the nozzle to a receiver, the inlet defining an inlet cross sectional area perpendicular to the flow of the material and outlet defining an outlet cross sectional area perpendicular to the flow of the material, the inlet cross sectional area being larger than the outlet cross sectional area; the nozzle being adapted with a plenum including an inlet port for receiving compressed gas and a chamber adapted to communicate the gas to the porous walls of the nozzle, and an outlet port for engaging a vacuum source to continuously evacuate the receiver while the nozzle is engaged with the receiver; a conveyor located at least partially within the conduit, the conveyor assisting the flow of material from the source to the receiver; and a liner member residing on to at least a portion of the inner surface of the conduit and adjacent to the nozzle.
