Bag filters, separate particulate from gas stream by causing the particulate to pass through a filtering media, a layer of previously collected (or purposely deposited) particulate, or both. To prevent excessive pressure drop as the particulate accumulates, these devices use various mechanisms to disengage the particulate from the media.

1.“Nuisance” venting of conveyors, transfer points, packing stations and so on — this dust is often sent to waste.
2.“Product collection” venting of classifiers, crushers, storage bins, air (pneumatic) conveying systems, mills, and flash dryers. This dust is often recovered because it has value.
3.“Process gas filtration” venting of spray dryers, kilns, power boilers, reactors and so on. The collected solids may or may not be returned to the process.
