Hopper Bottom Steel Silo
Hopper bottom Steel Silo, also known as cone bottom silos,Which is different from the flat bottom silo in shape. Hopper bottom steel silo is always a better choice for those who want small silos. Usually, a funnel is needed in the silo to store most of the material. For small silo storage, the hopper steel silo can be secured to the side wall. However, for large diameter industrial silos, the hopper/cone is designed to be supported by the bottom of the silo to reduce risk.
The lower part of the hopper steel silo has an angle of 45 ° and 60 ° which allows the grain to flow freely. While 45 ° hopper steel silo is used for grain, 60 ° hopper steel silo is used for feed, wet material and low fluidity material.
The limitation Of hopper bottom steel silo
Hopper bottom steel silo has it’s limitation, the diameter of hopper bottom silo is no more than 10m and the capacity is no more than 1500 tons.
The size of hopper bottom steel silo is depend on the natural flow angle of the storing material. That is to say, the smaller the natural flow angle of the material, the greater the height of the hopper bottom.
Normally, the natural flow angle of many material is general 40 degrees, such as grain and other material. When the steel silo has a large diameter, the upper beam of the foundation support structure will have to be greatly increased.
The biggest advantage of hopper bottom silos is they allow total cleanout by gravity without the use of sweep augers. There is less material handling equipment, less electricity needed for unloading, and much less maintenance required. Foundations for hopper bottom silos are more economical compared to flat-bottom silos, because they can be erected without subterranean trenches. Hopper silos with larger storage requirements can also be stiffened for extra security, expanding their capacity.
Hopper bottom silos have long served as working silos for repetitive receiving and discharge of grain. This application is especially useful for holding wet grain or rice before it enters a grain dryer. Also, these silos can be elevated on a structure, allowing the truck driver to drive up underneath the silo for ease of loading, without the need for expensive turnarounds.
