Conical smooth-walled silos
The silo is a cylindrical metal container made of a thin sheet shell, reinforced with a frame made of vertical posts, resting on a concrete base. Above the silo is covered with a conical roof.
Purpose of grain silos
Conical smooth-walled grain silos are manufactured with a useful volume of 6 to 1845 m3. The cylindrical silo has a zinc coating density of 450 g / m2, the vertical racks are located outside.
The maximum diameter of the cone silo is 11 m, the height of the cylindrical part is 16.86 m, the bottom depth is 5.5 m, the total height is 24.94 m. The bottom of the cone silos has an angle of 45 ° or 60 °.

Range of hopper bottom silos 45 ° AND 60 °
The conical roof of the silo has a rafter structure. The metal sheets are 1.5-3 mm thick (depending on the diameter and height of the silo).
The moisture resistance of the silo is achieved by using a special vulcanizing mass. The side segments are bolted with sealing gaskets. The bottom sheets of the side walls are thicker than the top ones.
Radial fans are installed outside the silo. The air supply volume is 8 m3 / h per ton of grain.
Air from the fans enters from below, through channels in the floor, passes through the grain and is drawn through the roof using a turbofan and deflectors (ventilators).
Grain silos are equipped with: Additionally:
active ventilation system;
deflectors (ventilators);
side and roof ladders;
side door;
roof hatch;
upper level sensor.
installation of vibration activators;
installation of thermometry (thermal suspensions);
control cabinet.
