A customer in Mexico has a process that involves adding plastics to a shredding device. The facility operates a cartridge collector and a knockout box. The plastic materials that come out of the shredder gets vented to the dust collectors above. The plastic is then fed via a screw conveyor to a rotary valve and into storage bags.

The company was having issues with the dropout box not getting enough removal and plastic particles were causing issues for the rotary valves. The company reached out to Aerodyne for a solution.

Aerodyne offered using a GPC to replace the dropout box and adding the GatorGate double dump valve to better handle the oversized plastic pieces. The GPC dust collector is a compact high efficiency cyclone dust collector. It has several distinct advantages over common high-efficiency cyclone dust collectors. The spiral inlet of the GPC directs the dirty gas stream toward the ground plate and hopper of the collector. Coupled with the compact size of the collectors, this gives the GPC the ability to be installed horizontally with virtually no effect on the collection efficiency. This cyclonic dust collector can improve any dust collection system. The GPC will remove around 99% of 20-25 micron and larger dust while the large chambers on the double dump valve will pass the over sized particulate.

The GatorGate is an efficient and reliable double dump valve available for the discharge of chunky, fibrous, and abrasive materials from dust collection systems. The unique cam operated drive mechanism provides reliable service without the use of expensive and problematic pneumatic controls. As the motor driven cam rotates, it actuates the upper and lower flap gates in sequence, allowing material to discharge while ensuring minimal leakage. Quick removing inspection doors provide easy access to internal components for regular maintenance and can be configured to operate using air or electricity. The GatorGate Double Dump Valve is available in a variety of sizes and is a great alternative for applications not suited for rotary air lock valves.
