Industrial Filtration, Separation & Dust Collection calculator
Solids Mass Loading Rate Calculator
Compare an observed dry-solids loading rate with your separator’s qualified limit. Enter inlet dry mass, observation hours and the approved handling rate.
What this calculator does
- Compare an observed dry-solids loading rate with your separator’s qualified limit.
Formula used
- Solids loading = Measured dry solids ÷ Elapsed hours
- Rate headroom = Qualified handling rate − Solids loading
- Window capacity = Qualified handling rate × Elapsed hours
Inputs explained
- Measured Dry Solids: Dry solids entering the separator during the recorded window.
- Loading Observation Time: Elapsed hours covered by the dry-solids measurement.
- Qualified Solids Handling Rate: Application-specific solids handling limit from equipment qualification.
How to use the result
- Best suited to separator feed reviews, solids handling capacity.
- Peak loading and changing particle distributions are not resolved.
Common questions
- Is this solids concentration? No. It is dry mass per hour; concentration needs a matched carrier flow or feed mass.
- Can I use hopper discharge weight? Only after reconciling inventory and collection losses to determine the inlet load.
- Does an average below rating prove adequate surge capacity? No. Check shorter observation intervals or recorded peaks separately.
- Where should moisture be removed? Convert the measured sample to dry solids before entering its mass.
