Grain storage grain silos (also called grain storage bins) are the efficient and economical facilities to handle your grains, 

which offer protection from outside insects and other affects as well as provide handling management conveniently.

All of our steel grain silos can be designed and installed with heat retaining layer to meet your special insulated grain storage demands.

Our innovative, high-quality flat bottom grain silos, hopper bottom grain silos, powder grain silos, feed grain silos, bucket elevators, 

dust collectors and grain storage control system are integrated as a system to satisfy your grain storage requirements.

*Hopper bottom grain silos (also called cone bottom grain silos, hopper bottom storage bins, hopper bins) 

are the steel grain silos with a cone bottom. Hopper bottom grain silos are erected on the supporting structure to 

make the delicate products unloading easily through gravity. Hopper grain silos have a smooth wall hopper transition 

with no steps or flanges to offer the cleanest product discharge from the grain silo. The stored products inside the grain 

silo are isolated from the ground, thereby preventing humidity and allowing the interconnection of grain silos through 

tapes, facilitating perfect extraction or dosage.


*Hopper bottom grain silos are widely applied for the storage of grains (sunflower seeds, soy, maize, sorghum, rice, 

industrial products and other products, etc) and feed pellets for animal, poultry and fish that require special storage 

conditions. They can also provide temporary storage of wet grain as part of a grain drying plant and other buffer bin 

applications in grain silo plants. They are widely used in poultry farm, rice mill, flour mill, soybean-oil mill, animal 

feed mill plant and brewery plant.

*The hopper, rings and support steel are made of hot-dip galvanized steel sheet. All our hopper cones for grain 

bins are designed in accordance D-4097 or ASTM D-3299 standards for elevated cone heads. According to the 

stored grain products and storing situations, the hopper or cone angles are commonly designed at 45º and 60º. 

The structure of hopper grain silo depends on the type of products to be stored. In generally, free flowing products 

pellet products like corn, wheat, soybean and feed pellets require the hopper bottom grain silo with a 45° angle 

while powder or other material which is hard to flow fits 60° cone bottom grain silo storage.



45 degree cone bottom bin (angle of bin top is 25 degrees), the height distance from the discharge outlet of all 

steel cone bottom bin to the ground is 1m, the galvanized layer of coaming and bin top cover plate is 275g / m², 

which is the inner column, and the part with diameter of 4.5 and above cone bottom is painted.
