Damp production areas see dust bridge in hoppers, cake on conveyors, and foul sensors. The result is inconsistent feed rates, more stoppages, and dirty changeovers. Treat humidity as a process variable and clumping becomes manageable.

Control the microclimate

Measure RH and temperature at problem points—above silos, along conveyors, and near doors. If RH is persistently high, use dehumidifiers to stabilise conditions around intake and transfer points. Insulate or heat-trace cold sections where dew point is reached to stop surface wetting.

Prevent formation at source

Design shrouds and local extraction at transfer points to capture dust before it settles and absorbs moisture. Keep capture distances short, reduce drop heights, and maintain airflow under load with staged pre-filters to limit clogging.

Handling and housekeeping

Avoid sweeping or air lances; both drive dust into bearings and electrics and create exposure. Use industrial vacuums with appropriate filtration (H13/H14 where fine or hazardous dusts are present). Clean short and often, especially before breaks or washdowns so residues do not hydrate and set.

Keep materials moving

Fit agitation or mass-flow liners in bins to prevent bridging, and set maintenance that targets build-up before it cures. Where food dusts are present, coordinate with hygiene teams so moisture control and allergen controls align with COSHH principles.

• Stabilise RH at intake, transfer, and storage points
• Capture at source with short throws and LEV
• Vacuum only; avoid sweeping and compressed air
• Schedule quick cleans before moisture can set residues
• Address cold spots that hit dew point

With stable humidity, tight source capture, and vacuum-only housekeeping, dust stops clumping and the line keeps running predictably.
