small hopper bottom silo Introduction

A small hopper bottom silo is a storage container with a relatively small capacity, typically used for storing various bulk materials such as grains, seeds, feed, cement, and fly ash. The bottom of this silo is designed in a hopper shape to facilitate the flow of materials and minimize the area where materials can become stagnant during storage.

Structure of small hopper bottom silo

Silo Body

Cylindrical Structure: Typically a cylindrical construction made from materials like steel or reinforced plastic, offering sufficient strength and durability.

Roof: Covers the top of the silo to protect the stored materials from external elements like rain, dust, and pests.

Bottom Structure

Hopper Bottom: The bottom is designed in a funnel shape to facilitate the smooth discharge of materials by gravity. This design helps in preventing blockages and ensures efficient material flow.

Discharge Outlet: Located at the bottom of the hopper, it connects to the conveying system to allow controlled release of materials.

Support Structure

Support Legs or Frame: Elevates the silo to provide clearance for the discharge outlet and conveying equipment. These supports are typically made of steel and ensure the stability and safety of the silo.

Foundation: A stable base, often made of concrete, that supports the entire structure of the silo.

Conveying System

Feeding System: Equipment such as small bucket elevators, augers, or pneumatic conveyors that transport materials into the silo from the top.

Discharge System: Includes mechanisms like slide gates, rotary valves, or screw conveyors to control and transport materials from the silo’s discharge outlet to the desired location.

Ventilation and Dust Control

Ventilation Equipment: Ensures proper air circulation to maintain material quality and prevent spoilage due to moisture accumulation.

Dust Collection System: Minimizes dust emissions during loading and unloading operations, protecting the environment and maintaining air quality.

Monitoring and Control System

Sensors and Gauges: Monitor the internal conditions of the silo, such as temperature, humidity, and material levels, to ensure optimal storage conditions.

Control Panels: Facilitate the operation of feeding and discharge systems, often incorporating automation for enhanced efficiency and ease of use.

Maintenance and Inspection Features

Access Doors and Manholes: Provide entry points for personnel to perform regular inspections, maintenance, and cleaning inside the silo.

Ladders and Platforms: Ensure safe access for operators and maintenance personnel to different parts of the silo.

Safety Features

Overfill Protection: Devices such as level sensors or alarms to prevent overfilling, which can lead to structural stress or spillage.

Emergency Discharge Mechanism: Allows for the rapid emptying of the silo in case of emergencies to prevent accidents or damage.

Advantages of Small Hopper Bottom Silo

Efficient Material Flow

Gravity Discharge: The hopper design at the bottom uses gravity to help materials flow, reducing blockages and accumulation, and improving discharge efficiency.

Continuous Discharge: With multiple discharge outlets, they can achieve continuous and even material discharge, suitable for production lines requiring constant operation.

High Space Utilization

Compact Design: Small silos occupy less space, making them suitable for storage needs in limited spaces.

Modular Structure: They can be flexibly adjusted or expanded as needed, accommodating various production or storage requirements.

Ease of Maintenance and Operation

Easy to Clean: Simple structure with no dead corners inside, making cleaning and maintenance convenient.

Convenient Inspection: Equipped with inspection doors and manholes, allowing operators to easily perform internal checks and maintenance, ensuring long-term reliable operation.


Low Construction Cost: Compared to large silos, small silos have lower construction and maintenance costs, suitable for small and medium-sized enterprises and farms.

Low Operating Cost: High degree of automation reduces manual operation, improves work efficiency, and lowers operating costs.


Wide Applicability: Can store various bulk materials such as grains, feed, cement, and coal, making them suitable for agriculture, industry, energy, and other fields.

High Flexibility: Can be adjusted and configured according to the characteristics of different materials, such as installing ventilation systems and moisture-proof equipment to ensure material quality.

High Safety

Dust Control Design: Equipped with dust removal systems to reduce dust pollution, protecting the environment and operator health.

Sturdy Structure: The robust design of small silos can withstand external environmental impacts such as wind, rain, and earthquakes, ensuring material safety.

Environmental Friendliness

Reduced Waste: Scientific storage and management reduce material loss and waste, enhancing resource utilization efficiency.

Eco-Friendly Design: Uses environmentally friendly materials and technologies, reducing environmental impact and meeting modern environmental protection requirements.

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.
