One Clarion’s bolted steel silos store cement, fly ash, lime, sand, plastic resin, and other dry powders with proven reliability. Flat-panel construction with factory-cured epoxy resists corrosion, and 45° to 70° cone hoppers with mass-flow or funnel-flow geometry promote consistent discharge. Configure pneumatic loading from truck or rail, aeration pads or air cannons, bin vents with cartridge collectors, level and pressure monitoring, and overfill protection. Optional OSHA-compliant ladders, cages, and platforms support safe access, while our team provides layout guidance, foundation interfaces, and installation support to help you commission quickly and maintain dependable material flow and long-term performance.
Dry Bulk Storage Tanks & Steel Silos
Bolted dry bulk storage tanks with epoxy coating and steep-cone hoppers. Reliable flow, aeration/flow-aid, bin vents, level monitoring, and load-out support.
Dry Bulk Storage Tanks Engineered for Reliable Flow
Who Uses Dry Bulk Storage Tanks, and How?
Plant / Operations Manager
Uses silos to keep powder, grain, and milled products moving and production on schedule. Chooses hopper geometry from 45° to 70°, sets mass-flow or funnel-flow, and specifies pneumatic loading, aeration, and bin vents for consistent discharge and fewer stoppages.
Maintenance & Reliability Manager
Focuses on safe access, clean-out, and predictable service. Select optional ladders, cages, platforms, and fall protection. Plans spares for valves, aeration, and sensors, and sets inspection routines for coatings, gaskets, and pressure relief.
EHS / Compliance Manager
Manages dust, noise, and safety compliance. Aligns bin vents and dust collectors with housekeeping goals, adds level alarms and overfill protection, and verifies OSHA compliant access and pressure relief sizing for safe operation.

Dry Bulk Storage Tank Applications
- Ready-Mix / Batching: Cement, Fly Ash, Lime - Keep powders dry and feeding consistently with epoxy-coated bolted silos, 45° to 70° hoppers, mass-flow geometry, pneumatic loading, bin vents, and cartridge dust collection.
- Plastics Processing: Pellets and Resins (PE, PP, PET) - Bulk silos reduce material cost and free floor space. Options include pneumatic conveyance, vacuum receivers, level monitoring, and gentle handling to protect resin quality.
- Agriculture & Food: Grain, Seed, and Milled Products - Protect from moisture and contamination while supporting controlled discharge to conveyors and mixers. Add aeration, level sensors, and overfill/pressure relief for safe operation.
- Dry Fertilizers: Urea, Potash, MAP, AMS - Flat-bottom or hopper-bottom bins for retailers and farms with reliable flow-aid, dust control during load-out, and inventory monitoring for efficient seasonal demand.
- Specialty Powders: Carbon Black, Titanium Dioxide, Silica - Configure flow-aid (aeration pads, vibration, air cannons) to mitigate bridging and ratholing. Use tight-seal fittings, bin vents, and explosion-venting where required.
- Public Works / Industrial: Sand and Road Salt - Covered or enclosed silos keep material dry and flowable for winter maintenance. Integrate load-out chutes, level sensors, and dust suppression for cleaner sites.
