FAQ

 

Q: What is the main difference between flat-bottom and hopper-bottom silos?

A: Flat-bottom silos are designed for high-capacity, long-term bulk storage (50t to 10,000t+), offering the lowest structural cost per ton. They require mechanical reclaim equipment (such as sweep augers) for clean-out. Hopper-bottom silos (2.6t to 1,500t) use a conical base to enable rapid gravity discharge without sweep augers, making them ideal for frequent unloading and quick material turnover.

Q: How do I correctly calculate the required silo storage capacity?

A: Silo dimensions should be calculated based on required volume (m3) and material bulk density (t/m3), not nominal tonnage alone. For example, 1,000 m3 of corn (bulk density approx. 0.75 t/m3) yields 750 tons of storage capacity, whereas the same volume accommodates only 600 tons of soybean meal (bulk density approx. 0.60 t/m3). Always confirm your material bulk density before finalizing silo height and diameter.

Q: Is a 275 g/m2 (Z275) zinc coating sufficient for outdoor storage?

A: Yes. A 275 g/m2 hot-dip galvanized coating provides excellent atmospheric corrosion protection for standard outdoor industrial and agricultural applications, delivering a service life of 20+ years. For extreme coastal, marine, or highly corrosive chemical environments, higher galvanized specs or custom protective coatings can be engineered.

Q: How do you prevent condensation and grain spoilage inside the silo?

A: Moisture accumulation is managed through a combination of thermal ventilation and condition monitoring. We integrate top roof exhaust vents, side-wall aeration blowers, and multi-point digital temperature cables. This allows operators to detect internal hot spots early and run forced air through the grain mass to balance temperatures and prevent moisture migration.

Q: Can OUMU supply the full handling system along with the silos?

A: Yes. We manufacture complete material handling systems to match your required filling and discharge rates (TPH - Tons Per Hour). Our scope includes heavy-duty bucket elevators, drag chain conveyors, belt conveyors, screw conveyors, slide gates, and support structures, ensuring exact mechanical and electrical fit at all transfer points.

Q: How are steel silos packaged and shipped for international delivery?

A: Wall panels, roof segments, and stiffeners are stacked, bundled, and secured on heavy-duty steel pallets to maximize container loading space (20ft or 40ft HQ) and minimize sea freight costs. All hardware, sealants, and smaller components are packed in reinforced wooden or corrugated crates to prevent shipping damage.

Q: Do you provide installation guidance for overseas projects?

A: Yes. We offer two installation options for international clients:
Direct On-Site Guidance: Dispatching experienced installation engineers to supervise local erection teams, manage foundation anchoring, and handle system commissioning.
Remote Technical Support: Providing detailed 3D assembly drawings, step-by-step installation manuals, and dedicated video engineering support.
