Dust control for silos and storage bays

A silo is the longest drop on site, into a closed cell where the displaced air has to escape somewhere. In a shed or bay the dust has nowhere to go, and the fall also sorts the material: coarse in the middle, fines drifting to the surface.

A DustCone hopper at the outlet delivers a consolidated column of material, which stays together as it lands.

Why a DustCone hopper suits it

• Dust stopped at the source, with far less on the beams, the lights and the floor.
• The pile stays mixed: fines land among the coarse grain instead of blowing to the top.
• At an East Asian grain terminal, the operator now fills each storage bay from one outlet where two were needed before, because the column drives into the pile and pushes it outward.
• Built for the drop: sized to the height, so the column holds to the bottom of the silo.
• No power, filters or compressed air to run.

Results depend on the site. Describe your bay or silo and the material and we will tell you honestly what to expect.

Common questions

Does a DustCone hopper make a silo or bay fill denser?

A mixed pile packs denser and more evenly than a sorted one, and DustCone has seen this at its own installations. It has not yet completed an instrumented measurement, so it does not quote a percentage.

Does it work on a tall silo drop?

Yes. Each unit is sized to the height of the drop, so the column holds together all the way to the bottom of the cell.

Can it bolt to the silo fill chute?

Yes. The flange-top FT bolts straight to the fill chute for a sealed inlet. The open-top DC hangs under an existing conveyor or tripper.
