Cyclone Dust Collectors
Many industrial processes require dust-size pieces of process material to be collected for reuse or disposal. Cyclone dust collectors are an efficient and low maintenance means of removing fine material from an air stream. Unlike filter-based dust collectors, cyclone dust collectors use the physics of air pressure, mass and momentum to cause particulate to fall to the bottom of a chamber where it can be collected. A cyclone dust collector has no moving parts and no filters; instead, it relies on the design and shape of the dust collector chamber. In cyclone dust collection, the air stream passes through tubes or around a stationary spinner that direct the air to rotate inside the chamber. Centrifugal force causes particulate to move to the walls of the chamber where it strikes the walls of the chamber, losing momentum. Then gravity pulls the particulate into a hopper at the bottom of the chamber. The particulate-free air (or other gas) rises through the center of the vortex and is vented at the top of the chamber.

Costs Associated with Dust Collectors
|
|
|
| In industrial applications, cyclone dust collectors are typically fabricated out of steel and are generally large. Most of the cost, therefore, is related to the cost of the metal. This is a one-time cost, unless highly abrasive material is being collected. Some dust collector manufacturers line their cyclones with abrasion resistant tiles to prevent wear.
One way to decrease the size and cost of dust collectors is to add a ground plate to the design. A ground plate is a stationary plate located at the end of the chamber (opposite the air inlet) that causes the cyclonic action to take place in a shorter space. Another way to reduce wear is to use a Counter-Cyclonic™ dust collector, in which a secondary stream of rotating air approaches from the opposite direction of the first air stream as a means to increases efficiency. The side benefit is that particulate loses momentum without touching the chamber walls, reducing wear.
Because the secondary air stream pushes particulate toward the collection end of the chamber, this design of dust collector does not rely on gravity for collection and may be installed horizontally instead of vertically. This may save significant cost by avoiding the need to cut a hole in the roof to accommodate a vertical dust collector, and it may save maintenance costs by avoiding condensation issues common with outdoor temperatures. Also, by drawing secondary air from an appropriate source, drying, heating, cooling or may be combined with the dust collection process, further reducing costs.
