Hopper bottom silos (alternatively called cone bottom silos, hopper bottom storage bins, hopper bins) are steel silos with a cone-shaped bottom. They are assembled on the supporting structure to allow the unloading of delicate products easily with the help of gravity.
Hopper silos include a smooth wall hopper transition minus any steps or flanges to offer the cleanest product discharge from the silo. Products that are stored inside these silos are at a safe distance from the ground, thereby avoiding any exposure to the humidity and allowing the interconnection of silos through tapes along with perfect extraction or dosage.
The hopper, rings and support steel used by Everyday Steels are made of hot-dip galvanised steel sheets. All their hopper cones for grain bins are conceived per D-4097 or ASTM D-3299 standards for elevated cone heads. Depending on the stored grain products and storing situations, the hopper or cone angles are commonly designed at an angle of 45º or 60º
