  • Life: 30-50 years
  • Body Plate: Galvanization Sheet
  • Application: It is used for grain storage, such as rice, wheat, corn, soybean, rapeseed, and other raw materials. It is essential equipment for the feed pellet plant, grain storage, grain factory, etc.

Flat bottom silo, is also called flat bottom bins or farm silo. It is designed for agricultural, industrial, commercial, and strategic applications such as large farms, inland storage facilities, grain terminals, grain-based factories such as flour mills, feed mills, rice mills, oil mills, and biofuel facilities.

What is A Flat Bottom Silo?

Flat bottom silo, is also called flat bottom bins or farm silo. It is designed for agricultural, industrial, commercial, and strategic applications such as large farms, inland storage facilities, grain terminals, grain-based factories such as flour mills, feed mills, rice mills, oil mills, and biofuel facilities. They can be used for short and long-term storage of grains, corn, soybeans, rice, oilseeds, and any other granular free-flowing material.

Our silo sheet of the drum wall is made of high-quality hot-dip galvanized steel. Our grain bins are also equipped with a scraper, belt conveyor storage system, cleaning and removing impurities, magnetic separation and iron removal, temperature measurement system, ventilation system, material change warehouse, and many other functions.

What is The Structure of Hopper Silo?

Silo Roof

The angle of the silo roof is generally designed to be 25 degrees to 30 degrees. This design can ensure the best structural strength of the silo rack, thereby maximizing the structure and safety of the silo. The silo roof adopts the strong interconnection design of the silo roof, the lower ring beam structure, and the side rib structure with the top cover plate so that the silo can withstand the worst of the silo load, the construction load on the top of the silo, and even the extreme snow load, and another extreme environment.

Stiffeners

Our silos are all made of high-tensile external reinforcement profiles to strengthen the entire silo body structure so that the silo can stand well even in extreme environments. And all reinforcing ribs are all galvanized to ensure that they will not rust for a long time.

Wind Ring

The air ring is mainly used to increase the strength of the hopper silo. For the tall hopper silo or the silo in a strong wind position, the air ring can effectively strengthen the load-bearing of the hopper silo, thereby effectively ensuring the firmness and safety of the silo.

High Strength Bolts

Our silos are all made of high-strength galvanized bolts, with nuts, sealing washers, and the use of sealant between the steel plates, which perfectly guarantees the sealing and firmness of the silos.

Manhole

Our silos generally provide two manholes. The first is usually located on the top of the bin for access from the top of the bin, and the other is usually located on the second bottom ring for workers to enter for clean-up or maintenance operations.

Ladder System & Rest Platforms

The ladders and rest platforms inside and outside the hopper silo are produced entirely in modular form by painted or galvanized sheets. The silo exterior safety ladder with a cage allows workers to reach the roof safely.
