The structure of grain steel silo

Cylindrical Body

This is the main part of the steel silo, usually made by rolling and welding galvanized steel plates to form a cylindrical shape. The cylindrical body is designed to provide sufficient strength and stability to withstand the weight of the stored grain and external environmental factors.

Base Structure

Includes the bottom of the silo and its foundation. The base is designed to bear the weight of the grain, often with a flat or conical shape to facilitate loading and unloading. The foundation ensures the stability of the silo and adapts to various geological conditions.

Roof Structure

The roof is designed to match the cylindrical body, providing enough space to accommodate loading and unloading machinery, such as loading bridges or conveyor belts, and ensuring smooth drainage of rainwater and snow.

Inlet and Outlet Systems

Grain steel silos require efficient inlet and outlet systems, including inlets, outlets, and conveyor equipment, to achieve rapid loading and transportation of grain.

Ventilation System

To control the temperature and humidity inside the silo and prevent mold and pest infestation, steel silos are usually equipped with natural or mechanical ventilation systems.

Sealing System

The sealing system of the steel silo ensures the airtightness of the structure, preventing external moisture, dust, and pests from entering.

Safety Facilities

Include fire protection systems, lightning protection systems, and rodent and pest control facilities to ensure the safe storage of grain.

Monitoring and Control System

Modern grain steel silos may be equipped with monitoring cameras, temperature and humidity sensors, grain quality monitoring equipment, and corresponding control software to achieve real-time monitoring and management of the internal environment and grain conditions.

Operating Platforms and Passages

For the convenience of operators in performing routine maintenance and inspections, steel silos are designed with operating platforms, ladders, and safe accessways.

These components together form the structure of a grain steel silo, ensuring the long-term safe storage and efficient management of grain.

Steel silos can be designed and constructed according to different geographical environments and storage needs, demonstrating strong adaptability.

Environmentally Friendly and Recyclable

Steel materials are recyclable, aligning with the requirements of sustainable development and reducing environmental impact.

Good Fire Resistance

Steel has good fire-resistant properties, which can reduce fire risks and protect the safety of grain.

Automated Operation

Modern steel silos can be equipped with automated loading and unloading systems and monitoring equipment, enhancing operational efficiency and safety.

Flexibility and Scalability

The design of steel silos allows for future expansion or modification according to needs, offering good flexibility and scalability.

Overall, grain steel silo are widely applied and appreciated in the field of grain storage due to their durability, sealing capabilities, construction speed, space utilization, maintenance costs, adaptability, environmental friendliness, fire resistance, automated operation, and flexibility.

Application scope of small steel silo

Coban steel silo is widely used for grain storage such as wheat, corn, soybean, paddy, rice, soybean meal, barley, malt, sunflower seeds, rapeseed, peanuts, flour, and other powder materials, oat, special Silo, and seeds, etc. These small steel silo offer excellent sealing properties, effectively preventing the grain from moisture damage, mold, and pests, ensuring the quality of grain during long-term storage.

barley steel silo technical parameters

Scientifically speaking, the Silo capacity should be measured with volume (m3). Even in the same grain Silo, the storage tons will be different for different grains with different densities. The following table is calculated based on a  Silo density of 0.75kg/m3, and surely HKB customizes  Silo systems unique for you.
