1. An alternative cyclone design uses a secondary air flow within the cyclone to keep the collected particles from striking the walls, to protect them from abrasion. The primary air flow containing the particulates enters from the bottom of the cyclone and is forced into spiral rotation by stationary spinner vanes. The secondary air flow enters from the top of the cyclone and moves downward toward the bottom, intercepting the particulate from the primary air. The secondary air flow also allows the collector to optionally be mounted horizontally, because it pushes the particulate toward the collection area, and does not rely solely on gravity to perform this function.
2. Large scale cyclones are used in sawmills to remove sawdust from extracted air. Cyclones are also used in oil refineries to separate oils and gases, and in the cement industry as components of kiln preheaters. Cyclones are increasingly used in the household, as the core technology in bagless types of portable vacuum cleaners and central vacuum cleaners. Cyclones are also used in industrial and professional kitchen ventilation for separating the grease from the exhaust air in extraction hoods. Smaller cyclones are used to separate airborne particles for analysis. Some are small enough to be worn clipped to clothing, and are used to separate respirable particles for later analysis.
1. The collected product remainls dry

5. Can be used under very extreme processing conditions
6. No moving parts
7. Constant Pressure Drop
8. Can be equipped with erosion or corrosion resistant
9. Can be fabricated with plate metal
10. Separate liquid or solid particulates,sometiome both in combination with proper design
1. Cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation.
2. When removing particulate matter from liquids, a hydrocyclone is used; while from gas, a gas cyclone is used.
3. Rotational effects and gravity are used to separate mixtures of solids and fluids.
4. The method can also be used to separate fine droplets of liquid from a gaseous stream.
5. Cyclonic separation can eliminate particulates, such as dirt and dust, from a stream of air, gas or liquid. Engineers sometimes call these tornadic dust busters centrifugal separators. That's because at the root of these machines is something called centrifugal force.
