Cone bottom silo are uniformly constructed using high-quality hot-dip galvanized steel sheets, which are pressed into a corrugated pattern by specialized equipment. Standardized molds are then punched to create standard connection holes, and finally, the components are connected using high-strength bolts.

cone bottom silo Introduction

The cone bottom silo, also known as the cone-bottom steel silo, cone-bottom storage, or cone-bottom steel tube silo, is a specially designed storage facility with a conical bottom. Typically constructed from galvanized corrugated sheets, these silos feature a modular structure divided into three main parts: the top, the body, and the cone bottom. Primarily used for storing granular products with good free-flowing properties, cone-bottom silos are ideal for materials such as corn, rice, wheat, soybeans, feed pellets, and plastic pellets.

Features of cone bottom silo

Conical Bottom Design

The conical bottom of the silo facilitates easy self-flow unloading of materials due to the force of gravity, making it convenient for material discharge and transportation.

Modular Structure

The modular construction of cone-bottom silos allows for easy and quick assembly and disassembly, enabling relocation or reconfiguration as needed.

Smooth Inner Walls

The inner walls of the silo are smooth, without steps or flanges, reducing resistance to material flow and ensuring smooth discharge.

Support Steel Frame Structure

Cone-bottom silos stand on a supporting steel frame structure, which enhances the stability of the silo and facilitates the loading and unloading of materials.

Moisture Protection Design

The silo is elevated above the ground to prevent stored materials from becoming damp, and it allows for interconnection between adjacent silos through conveying devices, facilitating the extraction of materials.

Standardized Design

The design of cone-bottom silos adheres to international standards such as D-4097 or ASTM D-3299, ensuring the quality and performance of the product.

Diverse Specifications

The capacity of cone-bottom silos ranges from as small as 20 cubic meters to as large as 1,875 cubic meters, allowing for customization of silo sizes to meet storage requirements.

Cone bottom silo structure

The structure of a cone-bottom silo is meticulously designed to meet specific storage requirements, encompassing several key components, each with its unique function and characteristics. Here are the main structural components of a cone-bottom silo:

Conical Bottom

The conical bottom of the silo facilitates natural flow of materials due to gravity during unloading. This bottom section is typically connected to the discharge outlet, ensuring smooth material flow out of the silo for loading and transportation.


The body is the main part of the cone-bottom silo, usually constructed from galvanized corrugated sheets known for their excellent corrosion resistance and strength. The design of the body takes into account the characteristics of the materials, such as flowability, density, and storage duration, to ensure the stability of the structure and the safety of the materials.


The top of the silo provides an enclosed space to protect stored materials from external environmental influences. It may also include ventilation systems and safety equipment, such as lightning rods and air vents, to maintain suitable conditions inside the silo.

Support Structure

The support structure of the cone-bottom silo includes steel frames or other types of supporting elements that ensure the overall stability of the silo. These structures are typically made from high-strength steel capable of bearing the weight of the silo and its contents.

Inlet and Outlet Systems

The inlet and outlet systems are integral parts of the silo, including the inlet for loading materials and the outlet for unloading. The design of these systems ensures that materials can enter and exit the silo efficiently and safely.

Ventilation System

To maintain appropriate temperature and humidity levels inside the silo, a cone-bottom silo is usually equipped with a ventilation system. These systems help regulate air circulation within the silo, preventing spoilage and mold growth of materials.

Control and Monitoring Systems

Modern cone bottom silo may be equipped with advanced control and monitoring systems for real-time surveillance of environmental conditions inside the silo, such as temperature, humidity, and material levels, as well as for operating automated loading and unloading equipment.

Application scope of cone bottom silo

Coban  Silo is widely used for grains storage such as wheat, corn, soybean, paddy, rice, soybean meal, barley, malt, sunflower seeds, rapeseeds, peanuts, flour, and other powder materials, oat, special Silo, and seeds, etc.

cone bottom 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.
