A cyclone separates particles from a rotating gas stream using centrifugal and inertial forces. This introduction explains the separation process; for equipment options, see TECHFLOW’s CyclaX cyclone dust collectors.
Dust-laden gas enters the body and follows a swirling path. Separated material moves towards the wall and discharges through the lower outlet, while the gas leaves through the gas outlet. The geometry and operating conditions influence separation.
A cyclone is often a precleaner ahead of a downstream collector. Removing a suitable coarse or abrasive fraction can reduce the particulate load on subsequent equipment. A cyclone is not a guarantee that every fine particle will be captured.
Performance must be assessed against the actual particle-size distribution, gas flow, temperature, density and required outlet condition. A quoted overall efficiency without the test conditions is insufficient for specifying a system.
A complete installation also needs suitable ductwork, fan selection and dust discharge. Air leakage, an obstructed outlet or operation outside the intended flow range can affect performance. Maintenance access should be included in the layout.
For further reading, see our cyclone selection checklist and the US EPA cyclone overview. Project selection is based on the process data and agreed requirements.
