Dust & DPM — Conveyor Transfer Spray Rate
Conveyor Transfer Spray Rate for mine air quality management.
Transfer points make most of a conveyor system's dust, and water works by wetting the FINES at the moment of fall — sprays aimed at the falling curtain, not the belt top. Over-watering backfires downstream (carry-back, plugged chutes); the L/t band here is narrow on purpose.
Formula
Note: Mine ventilation is statutory and life-safety territory: airflow quantities, gas limits and re-entry times must be set by the registered ventilation engineer/manager under your jurisdiction's mining regulations — this calculator is a planning and training aid.

About Dust & DPM — Conveyor Transfer Spray Rate
Dust & DPM — Conveyor Transfer Spray Rate computes the governing relationship L/min = t/h × L/t ÷ 60 ÷ atomization factor live as you type. Transfer points make most of a conveyor system's dust, and water works by wetting the FINES at the moment of fall — sprays aimed at the falling curtain, not the belt top. Over-watering backfires downstream (carry-back, plugged chutes); the L/t band here is narrow on purpose. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Dust & DPM — Conveyor Transfer Spray Rate
- 1Enter your values — Material throughput, Water addition rate, Spray pressure factor (sensible defaults are pre-filled).
- 2Read the live results: Water demand, Per 16-h day.
- 3Check the "with your numbers" line to see L/min = t/h × L/t ÷ 60 ÷ atomization factor substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Dust & DPM — Conveyor Transfer Spray Rate?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula L/min = t/h × L/t ÷ 60 ÷ atomization factor with authoritative sources cited on the page (MSHA 30 CFR Parts 57/75 — Ventilation standards; ACGIH — Threshold Limit Values (TLVs); McPherson, M.J., Subsurface Ventilation and Environmental Engineering)
- ✓Transfer points make most of a conveyor system's dust, and water works by wetting the FINES at the moment of fall — sprays aimed at the falling curtain, not the belt top.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the dust & dpm — conveyor transfer spray rate use?+
It evaluates L/min = t/h × L/t ÷ 60 ÷ atomization factor, exactly as published. Sources: MSHA 30 CFR Parts 57/75 — Ventilation standards; ACGIH — Threshold Limit Values (TLVs); McPherson, M.J., Subsurface Ventilation and Environmental Engineering. The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
Transfer points make most of a conveyor system's dust, and water works by wetting the FINES at the moment of fall — sprays aimed at the falling curtain, not the belt top. Mine ventilation is statutory and life-safety territory: airflow quantities, gas limits and re-entry times must be set by the registered ventilation engineer/manager under your jurisdiction's mining regulations — this calculator is a planning and training aid.
When is this calculator the right tool for the job?+
Conveyor Transfer Spray Rate for mine air quality management. A free mine ventilation & air quality tool. Over-watering backfires downstream (carry-back, plugged chutes); the L/t band here is narrow on purpose. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
