S&B cyclone separators rely on the proven principle of using centrifugal forces to separate substances. Our rough screening cyclone separator (GZA) is suitable mainly for the preliminary separation of particles with a larger size. For separating extremely fine dusts, we have developed a high-performance cyclone separator (HZA). Both variants have an outstanding price-performance ratio. A variety of equipment options as, e.g., a hard-wearing inner lining, allow to increase the cyclones' range of application and effectiveness even further.

Operating principle

Cyclone separators use the principle of centrifugal forces, whereby the separator itself remains stationary while the gases are set in rotating motion under the effect of their own flow velocity. To start, raw gas is conducted into the cyclone on a tangential path. The structure is tapered towards the bottom and thus accelerates the particles to be separated and pushes them into a circular trajectory.

The centrifugal force separates the particles from the gas flow, and pushes them against the cyclone wall. The external wall has a braking effect on the particles which then trickle down to the bottom of the separator under the force of gravity, and are removed continuously from the bottom using a rotary feeder. The ascending clean gas leaves the separator via a submerged tube installed at the cyclone's centre.
