For fines separation the centrifuge type separator has proven its function in the field due to the simple design and dependibilty. The most common gas type cyclone is mainly used in the wood, plastic and cement industries and through pneumatic transport in the chemical and food industries.
In the inner portion of the cyclone, the particle/gas mixture is transformed into a rotational direction. A centrifuge effect is created and moves the particles in a radial direction toward the outside of the inner cyclone walls. The particles are thus centrifically removed from the gas stream flow.
Cyclones are used for massive as well as flowing particles. A cylindrical container with conical lower area allows the gas to tangenically react through various inlet geometries. The inlet geometries create a rotational flow of the gases inside the cyclone. Through the circular air stream the designated particles for separation are sedimented and forced by centrifugal motion toward the outer wall of the separation area. These particles are directed in a spiral stream form in a downward motion along the conus and discharge to the dust bin container. A larger portion of the particles are centrifugally forced directly at the inlet area of the cyclone.
Abrasive dusts can cause excessive wear at the inlet of the cyclone.
