Cyclone Dust Collector

A cyclone dust collector improves the quality of air released from industrial and commercial processes, for example in a manufacturing plant. It does so by collecting dust and other impurities in the air or gas. 

What makes the cyclone dust collector special is that it uses vortex separation and not a filter like conventional dust collectors. The air and dust entering the cyclone are pushed into a circular direction, swirling at thousands of rpm, from a hose attached to a dust-generating instrument. This generates a centrifugal force that causes the outer wall to be heavier than air particles. 

Depending upon the use, cyclone dust collectors are equipped for either wide or narrow diameters. At low dust loads, small diameter cyclones provide good dust accumulation performance and a high pressure drop of 6 to 10 inches.

Cyclone Dust Collector Working Principle

From a hose attached to a dust-generating instrument, the air or dust entering the cyclone dust collector is pushed into a circular direction, swirling at thousands of rpm. This generates a centrifugal force that causes the outer wall to be heavier than air particles. Gravity allows the dust and dirt to spiral down before collected particles are automatically moved to the bin of the cyclone dust collector. 

The marble remains pinned by centrifugal force against the outside wall as it spirals down into the storage bin below. The air and the very fine dust are buoyant and are not influenced by the centrifugal force, so they quickly flow to the dust collector or shop vac filter or are vented outside into the middle of the cyclone and the outlet tube.

In order to minimize the dust load hitting the final filter, cyclone dust collectors may be used as separators, or as protective devices to remove large hot particles from the gas or air stream to prevent the filter content from being harmed. 

Cyclone dust collectors with high performance consume more resources and thus have higher operating costs. When used along with a final filter or additional  dust collector, lower efficiency cyclones are often more efficient as they allow a better mix of particle sizes to enter the filter material, which can help to prolong the usable working life of the filter material.

Why might I need a Cyclone Dust Collector?

In plastic processing facilities, cyclone dust collectors are also needed because traditional high-speed vacuum conveying systems transfer plastic pellets and flakes so rapidly that some are destroyed, causing dust and other issues. The soft particles will hit the surface of the transfer tube, generate heat due to friction, leave stains, and become hair strands. When they reach the wall or corner of the pipe, the particles of the hard material will shatter or rupture, producing "fines" such as small parts, debris, or ashes. The cyclone is very effective in isolating anything heavier than air such as liquid from the air.

Almost 100 percent of dust particles that are large enough to see through the naked eye are isolated. The cyclone is bypassed by about 100 percent of the very fine dust under 2.5 microns because it is buoyant in the air and thus does not impact the centrifugal forces as well as the airflow drag forces. 

The most dangerous to your wellbeing are particles under 10 microns because they fly to the full length of your lungs and transfer the chemicals used to process and bind wood directly into your bloodstream. That is why, without using a quality filter downstream, cyclone dust collectors can never be vented indoors.

Advantages of a Cyclone Dust Collector 

A cyclone dust collector significantly decreases the amount of dust that needs to be removed from fixed filter windows, which are much harder to access, detach, and disinfect. The repair interval associated with dust-collection instruments is significantly extended. In most situations, emptying and repairing the bin that collects the dust is the only maintenance needed. 

Cyclone Dust Collectors effectively reduce the possibility of conveyor output issues or damage to the vacuum pump caused by the clogging of fixed dust filter screens due to repair delays or the incorrect re-installation of dust filter housings during filter screen maintenance. If you discover that you have output problems with your conveying system due to clogged filters on your pumps and receivers or emptying the bin on the dust collector endlessly, there is a high chance that your life will be changed by a cyclone dust collector.
