For low cost and short installation time, the steel silo is more widely used in storage of cement, fly ash, slag powder, clinker, food powder, grain, and other liquid material storage. The field including grain & oil processing field, chemical powder field, industrial powder field.

Steel silo series are widely used in various industrial lines such as grain depot, farm, wooden pellets, sawdust, plastic pellet, seed, flour, starch, oil, feed, water storage, alcohol, wine, port, chemistry and so on, which are the very equipment for storage of granular and powder materials.

The hopper bottom steel silo is suitable from 50 ton, to 2000 ton.

Take example for the 250 ton bolted silo First, calculate how many person will install the bolted silo. Secondly, calculate how many days need to finish the silo installation. Then, calculate the cost according to local wage level.

Unlike warehouses, this is a vertical type of storage, which provides certain advantages:

• The first advantage lies in the occupied ground surface. This method requires less ground space, which is important if space is not available of if its cost is high like at ports.
• Another advantage lies in how easy it is to keep theoptimum storage conditions for the grain , by controlling the temperature, insects, mould, birds, which in long term storage facilities could result in an important economic loss.
• The third advantage consists of lower costs than that incurred from using warehouses, which entails the automation of the grain transport equipment. The loading as well as the unloading can be completely automated using a SCADA system and at a lower cost.
• Another advantage is lower assembling costs, since this element is designed specifically for this purpose and weighs less than a storage facility.
• Finally, we have the fact that it is less expensive overall, and this is probably the main advantage in comparison to grain warehouses.

Hopper silos are mainly used for the storage of delicate products, which could deteriorate during the unloading process (using augers). Another important reason for using hopper silos is the foundation. The hopper silo only requires one foundation slab while the ground silo requires a perimeter ring and slab for the bottom of the silo; also ventilation and unloading ducts must be built. If several large capacity ground silos are required, then a tunnel would have to be built underneath the silos in order to house the machinery.

Hopper silos are divided into farm or livestock types, with standard capacities of 4.6 to 63 m3 (3 to 41 T feed base 0.65 T/m3) and agro-industrial silos with capacities from 95 m3 to 2,100 m3 (70 to 1,600 T grain base 0.75 T/m3).

Flat bottom silos have standard capacities ranging from 100 to 41,500 m3 (75 to 31,000 T grain base 0.75 T/m3).

For the purpose of meeting the different storage needs of our clients, at Silos Córdoba we manufacture a wide range of elevated and ground silos

Civil works are required for the silo foundation. Access roads for trucks and electrical power are also required.

Silos are manufactured taking into account the specifics of each country, such as the weather (high temperature, snow and wind). The seismic activity of the area and the proximity to the ocean are also considered.
