Dust collector separates fine particles, reduces labor and material costs

July 6, 2009
The dust collector uses centrifugal force to efficiently separate out fine particles beginning at 20 microns. This collector can handle dusts such as, sawdust, fly ash, sand, coffee and many others. Units range in size from 50cfm to 18,000cfm and can be mounted vertically or horizontally. This cyclonic dust collector easily handles fibrous, sticky, hygroscopic and high-temperature materials that would tend to clog or damage filter bags or cartridges. Placed before baghouses or cartridge filters, the model greatly extends the life of filter media and reduces labor and material costs. Manufacturers and processors may use the dust collector as part of a manufacturing process or to meet OSHA standards for dust control in the workplace. The dust collector works by allowing primary air or gas and dust to enter the collector near the base of the unit. They are then forced upward through the spinner. During the dust separation process, clear air or gas is vented through the top of the collector. This creates a centrifugal effect that throws the dust particles down to the hopper base where they are collected for disposal or reuse. The dust collector’s unique design ensures that a minimal amount of dust particulate will come in contact with the collector walls. This feature allows the collector to easily handle highly-abrasive materials without special anti-abrasive coatings or extra heavy-duty construction.
