Grain silos(also called grain storage bins, grain bins) are the steel silos with a cone bottom.Assembly galvanized grain steel silos are erected on the supporting structure to make the delicate products unloading easily through gravity. Grain silos have a smooth wall hopper transition with no steps or flanges to offer the cleanest product discharge from the silo. The stored products inside the silo are isolated from the ground, thereby preventing humidity and allowing the interconnection of silos through tapes, facilitating perfect extraction or dosage.
The hopper, rings and support steel are made of hot-dip galvanized steel sheet. All Grain Silos in hot-dip galvanized hopper cone for grain storage 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 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 silo with a 45° angle while powder or other material which is hard to flow fits 60° cone bottom silo storage.
