Cone Bottom Silo

Cone bottom silos are modern storage solutions designed for efficient material storage and convenient unloading. They are widely applied in the grain,feed, building materials and chemical industries.

Their core advantage lies in the conical bottom structure,which uses gravity to realize gravity-flow material discharge.This design reduces material residue and lowers the cost of manual cleaning.

A cone-bottom steel silo is a type of assembled steel silo made of galvanized corrugated steel plates with a conical bottom.It is specifically designed for storing free-flowing granular materials such as corn, rice, wheat, soybeans, paddy, feed pellets, and plastic pellets.

Its structure consists of three parts:the silo top,the silo body,and the conical bottom. The entire silo stands upright on a supporting steel frame structure,allowing materials to be unloaded by gravity.The smooth inner wall,without steps or flanges,ensures smooth material discharge.The conical bottom slope is available in three angles: 40°, 45°, and 70°. The 70°conical bottom steel silo is suitable for storing granular and powdery materials with high viscosity.

Features: Gravity-flow silo,no manual labor required,energy-saving,and low foundation cost.

Cone bottom silos typically consist of three main components:

• Top section: Provides rain protection, ventilation and material feeding functions.
• Body section: The main storage structure, fabricated from galvanized corrugated steel plates connected via bolts or welding, delivering excellent sealing performance and structural strength.
• Conical bottom: Features an inclined conical design with common angles of 40°, 45° and 70°. The 45° angle is ideal for free-flowing granular materials such as corn and wheat, while the 70° angle is more suitable for powdery or highly viscous materials.

This structure enables materials to naturally converge toward the center under gravity.By opening the bottom discharge gate,the silo can be emptied rapidly without additional silo cleaning equipment,thus saving energy and reducing maintenance costs.

Do you know why many steel silos are cone-shaped?

The conical base of a steel plate warehouse increases the floor area,reducing the pressure of powdered materials on the bottom.While flat-bottomed warehouses present challenges for material handling, the conical base solves this problem.

Steel plate warehouses,especially those storing powdered materials,more rationally utilize a conical base design instead of the traditional flat floor.This conical base also saves on construction costs,as the conical base of large steel plate warehouses is made of concrete,which can partially replace the function of the steel plates.
