Advantages of Steel Silos

 

High strength and long life: The high-strength steel used in steel silos gives it excellent compression, tension and impact resistance. Advanced manufacturing technology and high-quality steel, combined with good anti-corrosion treatment, make the service life of steel silos up to 30-40 years.

 

Excellent sealing performance: The joints of the steel silo are strictly treated by welding or bolting, which can effectively prevent the invasion of rain, dust and pests.

 

Convenient construction process: The steel silo adopts a modular design, and all parts are prefabricated in the factory and then transported to the site for rapid assembly. This construction method greatly shortens the construction period. Taking a 1,000-ton steel silo as an example, it can usually be completed within 5-7 days.

 

Economic and environmental advantages: The light weight of the steel silo makes the foundation requirements lower, thereby reducing the cost of infrastructure construction. At the same time, it occupies a small area, and at a time when land resources are becoming increasingly scarce, it can make more efficient use of limited land resources.

 

Intelligent system integration: With the continuous advancement of technology, steel silos can integrate remote monitoring, temperature control, ventilation and other intelligent systems. Through the remote monitoring system, managers can understand the storage conditions of materials in the silo anytime and anywhere, such as material level height, temperature, humidity and other parameters.

 

 

Common types

Flat-bottomed Steel Silos
The bottom of a flat-bottomed steel silo is horizontal or slightly inclined. They are generally built directly on the ground or a concrete platform. Discharge requires auxiliary machinery, such as a screw conveyor, to transport the material from the bottom of the silo to the discharge port.

 

Conical-bottomed Steel Silos
Conical-bottomed steel silos have a conical or double-conical bottom. The conical part is made of welded or bolted steel plates. Under the action of gravity, the material automatically converges to the center of the cone bottom and is discharged directly through the discharge port, requiring no or only minimal auxiliary equipment.

 

Welded steel silo
A welded steel silo is a cylindrical metal silo manufactured by welding technology. You can use it for grain storage, building materials, coal, chemicals, and other bulk materials.

 

Assembled steel silo
Assembled steel silo is a kind of steel silo that is pre-processed in the factory and assembled on site with high-strength bolts. It has a fast construction speed and low technical requirements. the prefabricated steel silo uses less steel and has a lower cost under the same specifications.

Grain Steel Silo

 

Application
 

Food Industry

Used for the healthy and hygienic storage of food items such as flour, sugar, vegetable oil, and milk.

Chemical and Pharmaceutical Industry

Suitable for the safe storage of chemicals and pharmaceutical raw materials. Resistant to reactive materials.

Agriculture and Feed Industry

Ensures that feed, grains, and other dry products are stored protected from moisture.

Industrial Production Areas

Used for the storage of various types of raw materials such as dust, liquid, and granules before or after the process.

 

Craftsmanship

 

Preparation stage
Before manufacturing steel silo, a series of preparations need to be done. First, choose the appropriate steel plate material, usually galvanized steel plate or stainless steel plate, and choose the appropriate thickness and specifications according to actual needs. Secondly, according to the design drawings, cut and cut the steel plate to ensure accurate size. Finally, clean and derust the steel plate to prepare for subsequent welding work.

 

Welding stage
Welding is a key link in the manufacturing process of steel silo. According to the design requirements, the prepared steel plates are spliced and welded to form a complete steel silo structure. During the welding process, the welding quality must be ensured, the welding temperature and time must be controlled, and welding defects must be avoided. At the same time, attention must be paid to the control of welding deformation to ensure the flatness and stability of the steel silo structure.

 

Anti-corrosion treatment stage
In order to extend the service life of the steel silo, anti-corrosion treatment is required. Common anti-corrosion treatment methods include coating anti-corrosion and electroplating anti-corrosion. Coating anti-corrosion is to apply anti-corrosion coatings, such as paint, anti-rust paint, etc., on the surface of the steel silo to isolate the steel plate from the external environment and reduce corrosion. Electroplating anti-corrosion is to improve the corrosion resistance of the steel plate by electroplating corrosion-resistant metals such as zinc and chromium on the surface of the steel plate.
