Abrasive Blasting, Shot Peening & Surface Prep calculator
Dust Collector Loading Calculator
Dust collector load affects cartridge life, differential pressure, housekeeping, and permit compliance. This calculator helps surface prep teams estimate how many pounds of dust and fines the collector will see during a blast period.
What this calculator does
- Estimate captured dust load from dust generated per blast cycle, cycle count, collector uptime, and capture efficiency.
- maintenance or EHS needs to anticipate collector loading before a heavy coating removal or high-rust job
- Returns the expected pounds of dust captured by the collector during the blast window.
Formula used
- Gross dust load = dust generated per cycle × blast cycles
- Captured dust load = gross dust load × collector uptime × capture efficiency
Inputs explained
- Dust generated per blast cycle: undefined
- Blast cycles: undefined
- Collector uptime: undefined
- Capture efficiency: undefined
How to use the result
- Use it for filter planning, drum change scheduling, hazardous coating jobs, and collector performance reviews.
- Dust generation varies with coating, rust, media breakdown, air wash settings, and ventilation balance; verify with actual hopper or drum weights.
Common questions
- What is a blast cycle? Use whatever repeatable interval your shop tracks: one batch, one pot, one room load, or one shift segment.
- Does this estimate airborne exposure? No. It estimates collector load, not personal exposure or compliance sampling.
- Why include collector uptime? If the collector is down, bypassing, or pulsing poorly, less dust reaches the hopper and more stays in the room or ductwork.
- How can I validate the number? Compare the estimate to dust drum weights, hopper cleanout records, and pressure drop trends.
