Where DustCone hoppers work

Materials

Six material families. The same physics.

Cone angle, wall material and discharge geometry change with the product. The working principle does not.

Grain

Wheat, maize, barley, paddy, soybeans and meals

Every free-fall drop sheds fines and broken grains as airborne dust: lost product, respiratory exposure, and an explosion hazard in enclosed storage.

• Recovers fines back into the cargo instead of the air
• Reduces combustible dust concentration in sheds and silos
• Food-grade SS304 / SS316L builds available

Fertiliser

Urea, DAP, potash and granular blends

Fertiliser dust is product loss you can price per tonne, and a corrosive housekeeping burden across every surface it settles on.

• Keeps high-value granules in the load
• Cuts washdown cycles and corrosion on steelwork
• Corrosion-resistant SS304 / SS316L construction

Soda ash

Dense and light sodium carbonate

A fine, alkaline powder that becomes airborne at the slightest disturbance: irritating to airways and eyes, and quick to migrate across a terminal.

• Contains ultra-fine powder within the falling stream
• No air movement introduced at the transfer point
• Steeper cone variants for cohesive flow

Sulfur

Granular and formed sulfur

Generates combustible dust with a notoriously low ignition energy. Every uncontrolled drop raises the airborne concentration you are trying to keep down.

• Purely mechanical, with no electrics in the hazardous zone
• Lowers suspended dust concentration at the source
• Spark-conscious material selection on request

Mining and minerals

Silica sand, limestone, ores and concentrates

Abrasive materials at high tonnages, where visible dust means product loss, silica exposure and community complaints.

• Hardox and polyurea-lined builds for abrasion
• Cuts respirable silica at the loading point
• Sized for terminal-scale throughput

Wood pellets

Densified biomass pellets

Pellets abrade against every surface they touch, and each drop turns a fraction of the cargo into fines: combustible dust in an enclosed store, and tonnage that never reaches the boiler.

• Gentler, decelerated flow creates fewer fines
• Lowers combustible dust load in sheds and silos
• Keeps pellet durability within spec on transfer
