cone bottom steel silo

cone bottom steel silo Introduction

The cone bottom steel silo is a galvanized corrugated plate assembled steel silo with a cone bottom, which is mainly composed of three parts: the silo roof, the silo body and the cone bottom. This type of silo is mainly used to store granular products with good free flow, such as corn, rice, wheat, soybeans, feed pellets and plastic pellets.

Functional characteristics of cone bottom steel silo‌

Efficient Storage

With its robust structure and high-quality materials, the cone-bottom steel silo provides a secure and reliable storage space for various granular materials such as corn, rice, wheat, soybeans, feed pellets, and plastic granules. Its large-capacity design meets the storage needs of operations of different scales.

Convenient Self-Unloading

The cone-shaped bottom is a standout feature of this silo, allowing stored materials to be easily unloaded by gravity without the need for additional mechanical equipment, significantly improving the efficiency and convenience of material discharge.

Moisture and Humidity Resistance

By maintaining a height difference between the silo body and the ground, the design effectively isolates ground moisture, preventing stored materials from becoming damp and spoiling. Additionally, the use of galvanized corrugated sheets enhances the silo’s corrosion resistance, further extending its lifespan.

Interconnectivity

Adjacent cone-bottom steel silos can be connected through conveying devices, making the transfer of materials between silos more flexible and efficient. This connectivity allows for quick movement of materials from one silo to another as needed, supporting various production or processing demands.

Customized Services

Manufacturers of cone-bottom steel silos typically offer customization options, adjusting the silo’s dimensions, cone angle, and adding special features based on the customer’s specific requirements. This flexibility ensures that the silos can better meet the storage needs of different industries and materials.

Eco-Friendly and Energy-Efficient

The materials used in the construction of cone-bottom steel silos are recyclable, aligning with environmental principles. Their efficient storage and self-unloading capabilities also help reduce material loss and waste during storage and transport, achieving energy-saving and cost-reduction goals.

Cone bottom steel silo structure

Roof

The roof is the top structure of the cone-bottom steel silo, typically composed of the roof cover (roof cap), roof panels, and roof framework. The roof panels, usually connected by umbrella-shaped plates of varying sizes, are positioned below the roof cap and above the framework. The roof is designed not only to be sealed and rainproof but also to withstand the weight of dust removal equipment and other potential loads.

Body

The body is the main part of the cone-bottom steel silo, constructed from corrugated silo wall panels. These panels have a smooth inner surface without steps or flanges, allowing the stored grain or other materials to be easily discharged from the silo. The body is designed to ensure sufficient strength and stability to support the stored materials and prevent deformation.

Cone Bottom

The cone bottom is the lower structure of the cone-bottom steel silo, featuring a conical design. This design allows the stored materials to be easily unloaded by gravity. The cone angle is usually designed based on the type of stored material. For instance, free-flowing granular grains like corn, wheat, soybeans, and feed pellets may be suited for a 45° cone bottom, while powders or other difficult-to-flow materials may be better suited to a 60° cone bottom. The cone bottom structure not only aids in material discharge but can also save construction costs to some extent, as the cone bottom of large steel silos can be made from concrete, reducing the need for steel plates.

Support Structure

The cone-bottom steel silo is erected on a support steel frame structure, providing sufficient stability and support. The design of the support structure takes into account the weight of the silo body, the weight of the materials, and potential load factors such as wind pressure.

Additional Components

In addition to the main parts mentioned above, the cone-bottom steel silo may also include other components such as circular reinforcement bands, aeration unloading devices, material conveying equipment, control systems, and instrumentation. These components work together to ensure the proper operation and efficient use of the cone-bottom steel silo.

The main advantages of cone bottom steel silo

Smooth Discharge

The cone-bottom design allows materials to flow naturally, facilitating smooth discharge. During unloading, materials can easily exit along the cone bottom, reducing the chances of blockage and buildup. This not only increases discharge efficiency and shortens discharge time but also minimizes material residue, reducing waste.

Minimized Material Residue

The inclined angle of the cone bottom ensures maximum material discharge, reducing accumulation. This ensures that all materials are fully emptied from the silo, improving storage efficiency and reducing the risk of material spoilage, thus preserving the quality of the grain or other stored materials.

Enhanced Stability

The bottom design of the cone-bottom steel silo enhances the silo’s stability. Due to the smaller base area of the cone-shaped silo, shear forces at the bottom are reduced, thus increasing the stability of the silo and preventing accidents during material storage.

Cost-Effective Construction

For large steel silos, especially those storing powder materials, the cone-shaped bottom can help save construction costs. The cone-shaped bottom can be made of concrete, substituting part of the steel plate, thus reducing the amount of steel required.

Ease of Management

The design of the cone-bottom steel silo facilitates mechanized and modernized management. It can be equipped with modern systems and equipment, such as ventilation systems, temperature measurement systems, and unloading systems, enabling intelligent management of the storage process for grain or other materials.

Flexibility and Customization

The cone-bottom steel silo can be customized to meet specific needs, adapting to different sites and storage requirements. This flexibility allows the silo to be widely used across various fields and industries.

Moisture Resistance

The cone-bottom steel silo is elevated above the ground, effectively preventing moisture from seeping in and protecting the stored materials from becoming damp and spoiled. Additionally, the use of galvanized corrugated panels enhances the corrosion resistance of the silo, further extending its service life.
