Main Features of a Bolted Silo

Modular Design

The silo consists of prefabricated steel or metal plates and bolt components, enabling quick on-site assembly and disassembly, adaptable to different storage needs and site conditions.

High Strength and Durability

Made from high-quality steel, the structure is robust and durable, capable of withstanding the weight of large quantities of materials and external pressure, ensuring safe storage.

Excellent Sealing Performance

The bolted connection design and sealing treatment ensure good sealing of the silo, preventing moisture, air, and contaminants from entering, maintaining the quality of stored materials.

Quick Installation

The bolted connection allows for a simple and quick installation process, saving construction time and labor costs.

Easy Maintenance

The modular design facilitates maintenance and replacement of damaged parts, reducing operational costs.

Main Components of a Bolted Silo

Silo Body

Composed of several prefabricated steel or metal plates connected by bolts, forming the main storage space of the silo, with the surface of the plates treated for corrosion resistance and contamination prevention.

Top Cover

Seals the top of the silo to prevent external contaminants from entering, designed with ventilation or exhaust ports to maintain internal air circulation.

Bottom Structure

Includes flat bottoms or conical bottoms to support material storage and discharge operations, with conical bottoms aiding in natural material flow.

Loading and Unloading System

Includes conveyor belts, screw conveyors, or pneumatic conveying systems to load or unload materials from the silo.

Ventilation System

Includes fans and ventilation ducts to keep the internal air circulating and prevent material heating and molding.

Temperature Control System

Includes temperature sensors and control devices to monitor and regulate the temperature inside the silo, ensuring optimal storage conditions.

Monitoring System

Equipped with various sensors and monitoring devices to track the condition of the materials inside the silo in real-time, such as temperature, humidity, and material levels.

Safety Equipment

Includes explosion vents, fire alarm systems, and emergency exits to ensure rapid response in case of emergencies.

Main Advantages of a Bolted Silo

Flexibility and Expandability

The bolted connection design allows the silo to be expanded or reduced as needed, meeting storage needs at different stages.

Efficient Storage

Large capacity design and efficient loading and unloading systems ensure quick intake and discharge of materials, improving storage and management efficiency.

Durability and Low Maintenance Costs

High-quality steel and anti-corrosion treatment ensure the long service life of the silo, reducing maintenance and replacement costs.

Environmental Adaptability

Suitable for various climatic conditions, resistant to high and low temperatures, suitable for a wide range of applications.

Safety and Reliability

Precise structural design and comprehensive safety systems ensure the stability and safety of the silo in use.

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.
