Sand and gravel aggregate

As core equipment in modern industrial storage, sand and gravel aggregate steel silos have become the preferred storage solution for bulk materials such as sand and gravel aggregates, cement, and fly ash, thanks to their large capacity, high strength, environmentally friendly sealing, and automated management.

I. Structural Features: Modular Design and High-Strength Load-Bearing

Material and Process

Constructed from corrosion-resistant materials such as galvanized sheet, carbon steel, or stainless steel, with thicknesses ranging from 0.8 to 4.2 mm, these silos are mechanically rolled and molded into corrugated sheets, which are then assembled using high-strength bolts or spiral undercutting.

Spiral Steel Silos (Lipu Silos): Specialized equipment is used to roll steel sheets into spiral ribs, forming annular stirrups to enhance the silo's resistance to hoop stress. Available in diameters from 5 to 21 meters and heights up to 30 meters.

Prefabricated Steel Silos: Constructed from standardized modules, these silos feature a corrugated wall design for enhanced sealing. The silo eliminates the need for internal support columns, making installation and maintenance easier. Space Optimization

The silo's height-to-diameter ratio can reach 1:1.1 to 1:1.5, allowing for a single warehouse capacity of 10,000-100,000 tons and an effective volume of 60,000-80,000 cubic meters, reducing floor space by over 50% compared to traditional warehouses.

The cylindrical silo with a spherical-shaped roof, combined with a conical barrel foundation, maximizes space utilization.

II. Application Advantages: High Efficiency, Environmental Protection, and Economical

Improved Storage Efficiency

Automated Management: Integrated material level detection, automatic alarms, and intelligent loading systems enable remote monitoring and unmanned operation, reducing labor costs by over 30%.

Fast Material Loading and Unloading: The pneumatic unloading system uses air pressure to transport materials, achieving a discharge rate of up to 500 tons/hour, meeting the needs of large-scale production lines.

Outstanding Environmental Performance

The fully enclosed structure prevents dust leakage, and with a bag filter, dust emission concentrations are below 10mg/m³, meeting national environmental standards.

Waste materials can be recycled and reused, reducing resource waste. Significant Economic Benefits

Low Construction Cost: For the same capacity, steel silos cost 40% less than concrete silos, and the construction period is 50% shorter.

Long Lifespan: Galvanized steel is highly corrosion-resistant, with a service life exceeding 25 years and low maintenance costs.
