Introduction to Steel Silo

Here is a detailed introduction to steel silos:

Timeline of Development

The development of steel silos spans over a century, initially gaining widespread use internationally. The application of steel筒s for grain storage originated in the early 20th century, and by the late 1970s, steel silos had almost replaced any other type of grain storage facility in the international grain industry.

China's technology for steel silos in the grain industry started relatively late. In 1982, Honghe Farm in Heilongjiang Province introduced galvanized corrugated steel plate assembled silos from the United States, marking the earliest group of modern steel silos to appear in China.

Structural Type

Prefabricated Steel Plate Silos: These are assembled using high-strength bolts connected by electric torque wrenches, after the sheets are punched from mechanically or mold-pressed corrugated steel plates. The wall panels are corrugated, typically made of galvanized steel with thickness ranging from 0.8 to 4.2mm, with the maximum wall thickness reaching up to 8.4mm.

Modular Steel Grain Storage Silos

The Lippmann Grain Storage Silo, also known as the helical steel silo, is constructed by a spiral ascending reel storage machine. The reel storage machine includes a reel unwinder, edge roller, forming machine, triangular grab, and electrical control.

Large Welded Steel Plate Silo: Constructed primarily from steel welding, the silo body is cylindrical, with the top and bottom in spherical segment shape, and the foundation in a round truncated cone shape. The design is advanced, offering large storage capacity, with individual silo capacity ranging from 10,000 to 100,000 tons.

Features

Excellent overall performance and long lifespan: During the construction process, the specialized equipment enhances the load-bearing capacity of the silo's outer wall with helical ribs, resulting in superior strength, stability, and seismic resistance compared to other silos. The normal service life is up to 30-40 years.

High-seal performance and versatile applications: Utilizing specialized equipment for roll storage, bending and gasketing, offering excellent sealing properties. Suitable for storing powdery materials such as cement and fly ash, as well as grains, petroleum, and chemical raw materials.

Short construction time and low cost: On-site construction of spiral-locked steel plate silos, with rapid installation of the top and ground, and quick molding and bending line operations. No need for scaffolding or other auxiliary facilities, ensuring a short construction period. Additionally, fully made of thin steel plates, they are lightweight and cost-effective.

Compact and easy to manage: The height and diameter can be chosen from a wide range, with the minimum distance between two silos as low as 500mm, allowing for optimal space utilization. Additionally, with high automation and equipped with temperature and material level sensors, it offers convenient management.

Application Areas

Agricultural Sector: Used for storing wheat, corn, and other grain crops to ensure food security.

The industrial sector: Stores cement, ore, fly ash, and other industrial raw materials, enhancing the efficiency of raw material storage.

Food Processing Industry: Used for storing raw materials and finished products such as flour and sugar, ensuring food quality and safety.

Environmental Protection Sector: For instance, storing sludge processed from wastewater for subsequent handling and transportation.
