The Cyclones are devices that separate solids in powder or granular form from air and gases. In these devices, air flowing at cyclonic speed is made to rotate in a cylindrical vessel of suitable design. When the solid material attains high speed, it picks up centrifugal force and clings to the outer surface of the devices. An air outlet is provided in the center for air to go out while the solid material is not able to change direction but goes downwards and gets separated due to the action of centrifugal force.
