Hopper Bottom Silos are generally built on fabricated steel structures with the conical bottom made of steel plates and the corrugated sheets performed are assembled with bolts and nuts on circular purlins and vertical stiffeners with waterproof washers, cylindrically above the conical hopper with a sloped roof in the top. Ladders to climb and get into the silos, handrails, manholes etc are provided.
The grains will be discharged by gravity to the bucket elevator/belt conveyor for onward conveying. These silos can also be built on the top of the concrete conical hopper with beams and columns built in situ. Aeration, ventilation, temperature monitoring system as required are all provided to the built hopper bottom silos. Normally these steel silos are recommended for storage up to 500 tones of grains like paddy having the density of less than 550kg/m3. Alternatively, there is another option which is flat bottom grain silos.
