ABSTRACT:
A multiple-choke unit for transporting and metering particulate material wherein the material is compacted to bridging, disturbed and then recompacted as it is friction driven through a duct. The duct has two opposed walls moving between the inlet and outlet which have a surface area that is larger than the surface area of a stationary wall or walls which from the other part of the duct. The duct includes a plurality of chokes which bridge by compaction, disturb and recompact the material as it is friction-driven through the unit. The unit provides simultaneous transport and metering of particulate material. The unit may be used to transport particulate material under atmospheric conditions or into a pressurized system.
