Cyclone collectors control industrial dust emissions by utilizing centrifugal force to separate particulates from a gas stream.12

The process functions as follows:
* Vortex Creation: A dirty airstream enters a cylindrical chamber tangentially, creating a swirling vortex.1
* Particle Separation: Due to their greater inertia, larger particulates are forced outward against the chamber wall.1
* Collection: As these particles lose velocity through friction with the wall, they slide downward into a conical hopper at the bottom for periodic disposal.1
* Exhaust: The cleaned air then spirals upward through an inner cylinder and exits the top of the device.1

Cyclones are most effective at removing relatively coarse particulates, achieving up to 90 percent efficiency for particles larger than 20 micrometres. Because they are generally insufficient to meet stringent air quality standards on their own, they are typically employed as pre-cleaners followed by more advanced equipment, such as electrostatic precipitators or baghouses.12
