Fine dust collectors come in all shapes and sizes to suit almost every waste or nuisance dust environment imaginable. Typical components include a conveyor fan, filter media, cleaning mechanism, explosion release panel and a waste collection container.
Smaller dust collectors usually have the conveyor fan situated inside the filter unit on the clean side of the filter media. This configuration is the like a vacuum cleaner, the fan pulls the dust into the filter where it is trapped by the filter media. On larger collectors the conveyor fan is situated outside of the filter unit, this allows more flexibility in pairing fans and filters for a particular installation. Should for instance you need to site your filter along way from the source of dust, then a high pressure fan would be needed to convey the dust to the filter.
This media traps the dust and allows the air to pass through. Some common filter media types used in dust collectors are; paper, needle felt, cotton and woven mesh. Cartridge filters are usually pleated paper with a protective metal mesh. Needle felt and cotton are usually in the form of bags, socks or envelope bags. The type, size and amount of the dust to be collected will determine which filter media to use.
Most dust collectors have a cleaning mechanism incorporated to clean the filter media. Two common cleaning methods are reverse jet which pulses compressed air into the filter media against the normal flow and shaking which can be done manually or with a shaker motor. Reverse jet cleaning can be done while the dust collector is running and allows for continuous operation while the shaking method must be done when the dust collector is switched off.
Most dust can ignite if certain conditions are present. Explosion release panels are designed to release the build up of pressure within the dust collector in the event of an explosion.
