A manufacturing facility in OH that specializes in aluminum processing equipment utilizes a small cyclone in its application. The cyclone is used to remove aluminum chips from the exhaust air that leaves the dryer. The company was using a competitor’s cyclone and was having issues with the abrasiveness of the application affecting the efficiency of the cyclone. After contacting Aerodyne Environmental about the problem and inquiring about an abrasive dust collector, it was determined that the GPC industrial dust collector would be a good fit in this plant.
The aluminum chips are washed and then dried before being melted for casting. The chips are fed into the dryer on a conveyor system. Hot air is then passed over the chips, drying them as they pass through. Most of the chips fall out and move on further down the processing line. However, some of the chips are transported by the air and exhausted out of the dryer. This is where the GPC comes in to the process. This compact abrasive dust collector will be located in the exhaust to remove the aluminum chips before the air is recycled. In order to best suit the design and space at this facility, the company ordered a GPC with a vertical configuration with abrasion resistant steel to better handle the application.
The Aerodyne GPC Dust Collector operates differently than other dust collectors. A sloped spiral inlet directs the dirty gas stream toward a fixed ground plate and hopper of the dust collector. The ground plate forces vortex reversal to occur in a much shorter space, eliminating the need for a long, tapered body. As the dirty gas stream strikes the convex ground plate, fine particulate that has not completely made it to the dust collector walls is deflected into the hopper. The ground plate also shields collected particulate from the forces of the vortex reversal, acting as a barrier between the separation chamber and the collection hopper. This innovative design enables a compact dust collector to operate at high efficiency, even when installed horizontally.
