vertical silo Introduction

A vertical silo is an upright container used for storing bulk materials, effectively protecting and preserving them to ensure long-term storage and efficient utilization. Vertical silos are typically constructed from various materials such as reinforced concrete, bricks, blocks, or galvanized steel panels. Based on the materials used, they can be classified into reinforced concrete silos, brick silos, and steel plate silos.

Vertical silo features

Efficient Space Utilization

Due to their vertical design, vertical silo can achieve a large storage capacity on a relatively small land area. This is particularly important in urban areas where land resources are scarce, effectively conserving land and providing ample space for business development.

Structural Stability

Typically constructed from robust materials such as reinforced concrete, vertical silo offer excellent seismic resistance and durability. This ensures the safety of stored materials even under harsh climatic conditions.

Large Storage Capacity

The design of vertical silo allows for individual or multiple silo configurations, forming a large-scale storage system. This makes them suitable for major logistics centers and industrial facilities with significant material storage needs.

High Degree of Mechanization and Automation

Modern vertical silo are often equipped with advanced loading and unloading machinery and automated control systems, enabling automated material handling, improving work efficiency, and reducing labor costs.


Vertical silo can be designed and modified according to the characteristics of the materials to be stored, making them suitable for a variety of bulk materials such as grain, cement, and coal. Additionally, the design and material selection of vertical silos also allow them to adapt to different environmental and geographical conditions.

Relatively Low Maintenance and Operating Costs

The simple and sturdy structure of vertical silos results in relatively low maintenance costs. Moreover, their high level of automation also helps to keep operating costs under control.

Environmental Friendliness

The design of vertical silo can minimize material loss and environmental pollution, such as reducing dust dispersion through sealed designs and controlling the internal environment of the silo through ventilation systems to ensure the quality and safety of the materials.


Beyond serving as storage facilities, vertical silo can also be repurposed through adaptive reuse to become other types of buildings, such as museums and art centers. This provides new possibilities for urban renewal and the preservation of industrial heritage.

Silo Body

The silo body is the central part of the vertical silo, typically constructed from reinforced concrete, steel, or other durable materials. The design of the silo body must withstand the weight of the stored materials and potential environmental pressures, such as wind and seismic forces.

Silo Roof

Located at the top of the silo, the silo roof seals the silo body, protecting the contents from external environmental factors like rainwater infiltration or direct sunlight. The roof can be fixed or designed to open, facilitating the loading and unloading of materials.

Silo Wall

The silo wall forms the outer structure of the silo body. Its design considers the characteristics and storage requirements of the materials, as well as possible lateral pressures. The wall is usually thick to ensure structural stability and durability.

Silo Bottom

The silo bottom is the base structure of the silo body, designed to bear the weight of the materials inside the silo. The silo bottom typically includes discharge outlets and conveying equipment to allow for the smooth outflow of materials.


The funnel, usually located at the bottom of the silo, is a critical part for the discharge of materials. The design of the funnel ensures that materials can flow smoothly out of the silo without blockages.

Elevating Equipment

Elevating equipment is used to transport materials from the ground or lower levels into the silo. These can include screw conveyors, belt conveyors, or other types of mechanical lifting systems.

Loading and Unloading System

The loading and unloading system comprises the equipment used to load materials into and unload them from the silo. This may include truck loading stations, rail loading stations, or other forms of material reception and distribution points.

Ventilation System

The ventilation system controls air circulation within the silo, preventing the accumulation of gases due to the respiratory action or chemical reactions of the materials, ensuring a stable environment inside the silo.

Control System

Modern vertical silo are often equipped with an automated control system that monitors and manages the ingress and egress of materials, storage conditions, and the operational status of the entire silo.

Vertical silo advantages

High Storage Efficiency

The cylindrical design of vertical silo allows for a larger storage volume per unit area, enabling more materials to be stored within a limited space, thus enhancing the utilization of space.

Strong Structural Stability

Vertical silo are typically constructed with robust materials such as reinforced concrete, offering excellent seismic resistance and durability. This ensures that the silos remain stable even under harsh climatic conditions, safeguarding the stored materials.

High Degree of Mechanization and Automation

Modern vertical silo are often equipped with advanced loading and unloading equipment and automated control systems, facilitating the automated handling of materials, which increases work efficiency and reduces labor costs.

Environmentally Friendly

The use of advanced material handling technologies and equipment in vertical silo reduces energy consumption and minimizes dust pollution from operations, contributing to green storage and energy-saving emission reduction goals.

Good Ventilation

The unique structure of vertical silo provides good natural ventilation, and with the installation of forced ventilation facilities, it meets the temperature and humidity control requirements for various materials.

Application scope of Vertical silo

Coban  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.

Vertical 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.
