Abstract
An improved apparatus (30) for transporting the metering particulate material (40) including a transport duct (36) having an inlet (32), an outlet (34), and at least one moving surface (31) located therebetween having a downstream facing drive surface. The apparatus further includes drive device for moving the moving surface (31) between the inlet (32) and the outlet (34) towards the outlet, and means for compacting the particulate material sufficiently to cause the formation of a bridge composed of substantially interlocking particulate material (40) spanning the width of the transport duct (36). The apparatus is used to transport and meter particulate material under ambient conditions and against pressure.
