Flat bottom industrial silos – OS range
These silos must be constructed on a flat slab. The standard design is for central and gravity emptying. They are designed to store any kind of dry and easy flowing cereals (wheat, maize, barley, rye, soya beans, field peas, rice, sunflower, rape seeds…). For some applications a specific design is necessary (oilseed cake, industrial pellets, wood pellets…).
According to the size of the silo, the stiffener shape is of “Ω” or “C”. They are placed outside with a distance of 93cm between each row.
The bolts are from class 8.8 or 10.9, according to the required resistance. The bolts are hot dip galvanized by soaking in melting zinc, resulting in the zinc being very thick. Rubber seals are used for tight sealing of the silo. The silo is anchored to the foundation with anchor bolts and flanges, allowing the movement of the base of the silo, when necessary, during the filling and emptying of the silo.
Privé silos are available in a large range of height and diameter (see table of capacities). Sometimes, Privé must adapt the silo to the special environmental characteristics (wind, snow, seism).
