Dust mitigation

What this service covers

Practical, source-by-source dust reduction for existing plants — the fixes that don’t require a capital project. Transfer-point sealing and skirting, belt support that closes the gaps skirting can’t, containment and enclosure, targeted suppression points, and housekeeping-driven changes that stop dust from being generated in the first place.

Typical wins

• The dusty transfer point. Sealed with skirting, belt support and dust curtains — a one-day fix in many cases.
• Carryback dust. A properly tensioned cleaner system stops dust you didn’t know was belt-borne.
• Loadout clouds. Fill-point suppression and containment where trucks and railcars load.
• The one machine fogging the building. A single capture point ducted to an existing or small dedicated collector.

Source-by-source: where dust starts

The mitigation ladder

• 1. Don’t make the dust — drop heights, chute design, belt speeds, material moisture.
• 2. Keep it in the process — skirting, enclosures, settling zones.
• 3. Knock it down at the source — suppression where it escapes anyway.
• 4. Capture what’s left — collection for the fine fraction and the indoor spaces.
• Most plants try to start at rung 4. The cheap wins live on rungs 1 and 2.

What to have ready

• A dust map — even hand-drawn: where it’s visible, worst time of day, which materials
• Complaint history — neighbors, regulators, or your own crews
• What’s been tried — and what it did or didn’t do
