Modular Bulk Storage for Grains, Seeds, Powders and Pellets with Maximum Space Efficiency
Engineered for the Future | Since 2080
The ADDAMS Square Silo is a modular, space-optimized bulk storage unit designed for high-volume handling of grains, seeds, powders, and granular materials. Its square footprint allows for maximum capacity within minimal floor space, making it the ideal choice for indoor installations, multi-bin systems, and customized layouts in food, feed, and industrial processing facilities.
Engineered for long service life, precise flow, and easy integration with downstream processing lines, the ADDAMS Square Silo is available in a wide range of capacities and materials to suit hem hygienic hem de heavy-duty requirements.
Square Silos Overview
Space-Efficient Modular Storage
The ADDAMS Square Silo series is specifically designed for facilities where every square meter counts. Unlike traditional round silos, the square design eliminates dead space between units when arranged in rows or blocks, increasing total storage volume by up to 25% within the same building footprint.
Reliable Flow and Industrial Integrity
By utilizing a bolted panel system, these silos provide exceptional structural strength while remaining flexible for future expansion.The design focuses on maintaining product quality, ensuring that seeds, grains, and powders remain protected from environmental factors while being ready for immediate discharge.
Operating Principle of the Square Silo System
Optimized Material Discharge (FIFO)
The system operates on the First-In, First-Out (FIFO) principle. Material is loaded through the top inlet and settles uniformly across the square cross-section. The hopper at the base is engineered with specific steep angles to ensure that gravity pulls the material downward evenly, preventing the “bridging” or “ratholing” common in poorly designed storage units.
Modular Assembly and Expansion
The silos are manufactured as high-precision panels that are bolted together on-site. This modularity not only makes transportation easier but also allows plants to add height or link multiple silos together into a “silo bank” as their storage requirements grow over time.
Key Features of the ADDAMS Square Silo
-
Space-Efficient Square Design: Offers maximum volume per unit area, ideal for tight plant layouts, silo banks, or linear arrangements.
-
Modular Bolted Construction: Made from precision-engineered panels, allowing for easy on-site assembly and future capacity expansion.
-
High-Flow Discharge Hopper: Fitted with 60 degree or 70 degree cone angles and smooth internal surfaces to ensure full flow and prevent material hang-up.
-
Durable Material Options: Available in galvanized steel, powder-coated carbon steel, or AISI 304/316 stainless steel for food-grade and corrosive applications.
-
Automation Ready: Designed to interface seamlessly with load cells, level sensors, conveyors, and centralized PLC systems.
-
Gasketed Joint Technology: All panel joints are sealed with high-quality gaskets to ensure the structure is dust-tight and weather-resistant.
Applications of Square Silo Systems
Grains, Seeds, and Pulses
Safe and organized storage for corn, wheat, barley, sunflower, soybeans, and chickpeas.
Powders and Flours
Ideal for rice flour, wheat flour, milk powder, and starch, especially when equipped with fluidization or vibration aids.
Pellets and Granules
High-capacity storage for animal feed, plastic pellets, fertilizers, and salt.
Process Buffer and Surge Bins
Used as temporary storage between cleaning, sorting, and packaging stages to maintain a continuous production flow.

Frequently Asked Questions – Square Silos
Why choose a square silo over a round one?
Square silos maximize space. In a row or grid, they eliminate the empty gaps found between round silos, allowing you to store more product in the same amount of floor space.
Is it difficult to assemble on-site?
Not at all. The modular bolted design is like an industrial assembly kit. This allows us to ship the silo in compact sections, which are then bolted together by a small team without the need for on-site welding.
Can I store fine powders in these silos?
Yes. For fine powders, we offer silos with AISI 304 stainless steel interiors and steeper hopper angles, often combined with vibratory or fluidization systems to ensure the powder flows smoothly.
How do I monitor the level of the product inside?
We can equip each silo with ultrasonic or radar level sensors, as well as load cells under the legs, providing real-time data to your PLC or mobile device.
Can the silo be expanded later?
In many cases, yes. Because of the modular panel design, height can often be increased by adding more panel rings, provided the support structure and foundation are designed for the additional load.
Are they suitable for food-grade products?
Absolutely. Our stainless steel (AISI 304/316) versions are specifically manufactured for the food industry, featuring smooth internal welds and food-safe gaskets to meet hygiene regulations.
