STORAGE

Grain silos

Our silos are designed to offer efficient and safe storage solutions for bulk products. With a robust structure, they guarantee an orderly and accessible management of the stored material.
 
Our storage silo designs cover both mechanical and pneumatic filling. In the latter case, the silo is equipped with its corresponding filter.

Features

Capacity

Square silos

Square silos offer up to 25% more storage capacity than round silos with the same surface area, making them ideal for bulk goods.

The body of our silos is built in "ZIG-ZAG" folded sheet metal at a 60º inclination, with hoppers and counter hoppers designed to ensure the correct inclination according to the product. They incorporate inspection and maintenance gates and suction filters in the upper part. 

Conservation

Cylindrical silos

Cylindrical silos, with sloping roof and flat bottom or hoppers with adjustable slope, are suitable for storing grains, cereals, seeds and flours. They are ideal for the storage of large volumes of raw materials for extended periods of time, available in various capacities, heights and diameters.

Frequently Asked Questions

What are the advantages of a flat bottom silo compared to other types of silos?

Flat bottom silos allow for greater storage capacity and are ideal for extended storage. Their design facilitates better grain management with efficient sweeping and ventilation systems.

What is the service life of a galvanized silo?

Thanks to their Z-600 quality zinc coating (600 g/m²), these silos are highly resistant to corrosion, with a long service life even in aggressive or humid environments.

What regulations do Rosal silos comply with?

They are designed according to ANSI ASAE EP 433. This guarantees a safe design and conforms to international agronomic standards.

Can silos be installed in seismic zones?

Yes, these silos incorporate anti-seismic reinforcements designed to resist seismic accelerations of up to 0.2 g, in accordance with UBC standards.

What type of access do flat bottom silos have?

They include multiple access points: interior door, eave platform, vertical stairs from the ground, walkways and automatic locking system for operator safety.

How is the grain ventilated inside the silo?

They have a system of aeration composed of fans and aeration domes that keep the grain in optimal conditions for long periods of time.

How are flat bottom silos emptied?

By means of mechanical sweeping with a central tractor, which allows an efficient and complete discharge of the contents, even in products with low fluidity.

What is the wind resistance of these silos?

They are designed to withstand wind speeds up to 144 km/h, equivalent to 100 kg/m² or 0.98 kN/m² lateral load.

What is included in the standard silo equipment?

Includes complete roof, galvanized hardware quality 8.8 or 10.9, anchor kit, level sensors, aeration system, platforms, ladders and safety access.
