The dust laden air enters into the cylindrical/conical body of cyclone tangentially at the top and the flow assumes a vortex pattern as it travels helically downward. The centrifugal force from the air’s tangential velocity causes the heavier dust particles to move radically outward towards the cyclone’s wall. When the particles reach the wall, friction and gravity force them to descend and discharge into a receiver at the bottom of the cyclone. The clean air spirals upward and exists at the top of the cyclone..
