摘要： A shut-off device for selectively stopping the flow of conveyed loose bulk materials in a conveyor conduit includes a housing (2) with a flow passage (3) therethrough, and at least one shut-off element (4, 5) movably arranged in the housing. The at least one shut-off element (4, 5) is driven by at least one drive (7, 8) and is arranged in such a manner that it moves between a first open position in which the flow passage (3) is completely open, and a second nearly closed position in which the flow passage (3) is nearly but not completely closed. Namely, a flow gap (6) preferably having a dimension on the order of the particle size of the goods to be conveyed, remains open even when the shut-off element (4, 5) is in its most-closed position. Particles of the conveyed material become caught on or in the gap (6) to effectively close off and stop the flow of conveyed materials. Avoiding the complete closure of the flow passage (3) prevents particles of the conveyed material from interfering with the closing operation or become pinched by the closing shut-off element, and the required closing force is reduced. Such a shut-off device can be arranged in series with a second shut-off device that completely closes the flow passage in an airtight sealed manner, whereby this second shut-off device does not have to separate or pinch off the flow of solid material particles.

摘要： Material feeding apparatus having, as one aspect, combining the loading, feeding and refilling functions in a single, vertically disposed housing with a feeder hopper portion of the housing below a refill hopper portion of the housing and separated from the refill hopper portion by a divider wall. The passage of material from the refill hopper portion to the feeder hopper portion is through a valve and material is drawn into the refill hopper portion by a vacuum source and discharged to the feeder hopper portion in response to indications of the level of the material in the refill hopper portion and the feeder hopper portion. A second aspect of this material feeding apparatus is the use of a flap valve as the valve which determines the passage of material from the refill hopper to the feeder hopper. A third aspect of this material feeding apparatus is combining two or more such systems in a blender and loading the systems with a single vacuum source which is selectively indexed to load the individual systems with constituent parts of a blend as the demand for material is sensed.
