Industrial Filtration, Separation & Dust Collection calculator
Cyclone Efficiency Calculator
Use this calculator to review cyclone collection efficiency for dust, chips, fines, or particulate streams. It helps engineers compare captured solids against inlet solids before deciding whether the cyclone protects downstream filters or meets separator expectations.
What this calculator does
- Calculate cyclone collection efficiency from captured solids, inlet solids, and target collection efficiency.
- Use it when checking cyclone separator performance, precleaner loading, cut point assumptions, or downstream filter protection.
- The result shows the share of inlet solids captured by the cyclone.
Formula used
- Cyclone collection efficiency = captured solids mass ÷ inlet solids mass × 100
- Cyclone efficiency gap to target = cyclone collection efficiency - target cyclone collection efficiency
Inputs explained
- Captured solids mass: Use dust, chips, fines, or particulate mass collected by the cyclone during the test or operating period.
- Inlet solids mass: Use total solids entering the cyclone over the same period, before collection losses or bypass.
- Target cyclone collection efficiency: Use the design target, cut point expectation, permit assumption, or supplier performance target.
How to use the result
- Use it to evaluate separator performance, precleaning, and downstream filter loading.
- It depends on particle size distribution, inlet velocity, air density, dust loading, and measurement accuracy.
Common questions
- What is the cyclone efficiency calculator for? It calculates collection efficiency for a cyclone separator.
- What information should I enter? Use captured solids mass, inlet solids mass, and target efficiency.
- What does the result tell me? The result helps judge whether the cyclone is protecting filters or meeting separation targets.
- When is the result only an estimate? It is only an estimate when particle size, inlet velocity, dust loading, or sampling accuracy changes.
