Have you ever been on “the scrambler” at the amusement park? If your answer is “yes”, then you have experienced firsthand the principles of a cyclone. By spinning around on the ride, the person on the outside gets squished by the person on the inside. Why? Because of centrifugal force. This is a form of artificial gravity. In fact, the faster the spin the more “gravitational force” or “g-force” is created and the more quickly the particles move to the outside.
In a cyclone, a process gas, is caused to spin. This creates a “g-force” on everything in the gas. This force causes particles and dust to be moved to the outside of “the ride”. Then when the gas is turned to exit the cyclone, the momentum of the particles allows them to be separated from the gas stream! The longer/taller the cyclone is, the longer the particle is “on the ride”, and the more efficient the separation.
Now you will never look at a cyclone the same.
