Structure and Features of SDCAD Big Bag Silos

SDCAD big bag silos are engineered for ease of use and stability:

Easy Access: The hatch on the roof opens effortlessly, simplifying material loading and inspection.
Efficient Unloading: Equipped with a big bag opening device, ensuring smooth material discharge.
Safe Platform: A grid platform remains in place after the big bag is emptied, providing a secure area for operations.
Convenient Access to Top: A ladder leads to the top of the silo, facilitating maintenance and inspection.
Safety Railings: Railings on the silo roof enhance worker safety during tasks at height.
Stable Construction: Transport brackets and a large base plate keep the silo upright on-site, ensuring stability.
Easy Relocation: Lifting lugs allow for convenient movement of the silo when needed.

Various Applications

Tailored Accessories for Various Applications

SDCAD offers a range of accessories to customize big bag silos for different materials:

For Granules: The bottom cone can be fitted with components like Triotec’s bottom hopper, shut-off gates, and conveyor belts for seamless material transfer.
For Dry Concrete or Cement: The bottom cone can be equipped with shut-off gates and automatic agitators to prevent material caking and ensure consistent flow.
For Winter Use: The lower part of the silo can be covered with plywood and outfitted with front canopies, protective tarps, or plywood cladding to withstand cold weather conditions.

SDCAD: A Leader in Welded Steel Silo Manufacturing

With over 30 years of experience, SDCAD has established itself as a trusted name:

High Production Capacity: Our factory produces 1,700 – 2,300 silos in bulk annually. Popular models are also available in stock for faster delivery.
Quality and Durability: Our high-quality silo series is built to withstand the test of time, corrosion, and harsh northern climates. We manufacture welded steel silos with legs and bottom cones, known for their robust construction.
Certifications and Standards: SDCAD steel silos are CE-certified and meet the strict requirements of the SFS 1090 standard. Silo dimensions are carefully designed to withstand various extreme weather conditions, with strength calculations and tests conducted for typical snow and wind loads in northern climates.
Specialized Silos: Beyond big bag silos, we also produce special silos such as square silos for bioenergy production and other custom silos based on customer requirements.

Application: Big Bag Silos in Cement Storage

SDCAD vertical cement silos, featuring a fully welded structure with height-adjustable support legs, are ideal for free-flowing materials like Portland cement or lime (with a bulk density of 1.13 tons/m³). The complete configuration includes: cement screw conveyors, counterweights for cement screw conveyors, cones with outlet flanges, top openings, cement inlet grilles, big bag cutters, control units, a set of wires and connections, and lifting devices (suitable for forklift transport too).

The big bag silo with a bag breaker can also function as a weighing hopper. Equipped with scales and a control box, it regulates the cement loading amount. This type is mainly used in dry-mix and wet-mix concrete batching plants. Additionally, big bag silos can be used in conjunction with portable container silos. Bagged cement is first loaded into the big bag silo and then transferred to the container silo for storage.

Whether you need a big bag silo for cement storage, a jumbo bag silo for granules, or a big bag hopper for specialized material handling, SDCAD provides customized solutions. Contact us today to find the perfect bulk storage solution for your needs.

ype of Big Bag Silo Systems

A big bag silo is a bulk storage solution designed specifically for storing and handling cement, fly ash, or other powdered materials delivered in bulk bags (FIBC). These silos are equipped with a top loading hopper and bottom discharge system, allowing quick transfer from big bags to concrete batching plants or industrial production lines. Big bag silos are ideal for projects that require rapid material replenishment, modular installation, and flexible transport.

Difference Between Types of Big Bag Silos

Big bag silos can be categorized based on capacity, loading method, and discharge system:

By capacity: Standard sizes range from 20 to 50 tons, designed to accommodate multiple big bags simultaneously.
By loading type: Manual hoist loading or forklift-assisted loading. Some models include integrated bag lifting frames for automated operation.
By discharge method: Screw conveyor or pneumatic discharge systems for controlled material feeding.
By mobility: Skid-mounted, stationary, or semi-mobile units depending on project requirements.

Compared to traditional silos, big bag silos offer fast material exchange, flexible placement, and reduced dependency on bulk powder delivery pipelines, making them suitable for remote or modular batching setups.

Applications of Big Bag Silos

Big bag silos are widely used in:

Ready-mix concrete plants for batch feeding cement or fly ash directly from bulk bags.
Mobile concrete batching systems where pipeline installation is impractical.
Dry-mix mortar production for small or medium-scale industrial operations.
Infrastructure projects in remote locations where cement delivery in bulk bags is preferred.

These silos provide a dust-free, efficient, and easy-to-maintain solution for projects with intermittent or modular material supply needs.

Main Technical Specifications and Performance Indicators

Key specifications include:

Capacity: 20–50 tons
Discharge outlet diameter: Φ219–Φ273 mm
Feeding system: Top loading via hoist, forklift, or bag frame
Discharge system: Screw conveyor or pneumatic feeder
Material: Q235B carbon steel with epoxy coating or galvanization
Dust collection area: 15–30 m²
Height: 5–8 meters, depending on bag capacity and installation requirements

Key performance indicators:

High filling efficiency — accommodates multiple big bags with minimal downtime.
Smooth discharge — prevents blockages and ensures continuous feeding to mixers.
Dust control — integrated filters reduce environmental contamination.
Easy maintenance — simple structure allows quick inspection and cleaning.

Price Factors and Price Range

Price depends on:

Capacity — larger silos require thicker plates and stronger support structures.
Discharge system — automated screw conveyors or pneumatic feeders increase cost.
Material and coating — galvanization or epoxy-coated steel adds durability but also cost.
Accessories — dust collectors, level sensors, or hoist systems affect the final price.

Typical price range:

Small (20 tons): USD 5,000–7,500
Medium (30–40 tons): USD 7,500–10,500
Large (50 tons): USD 10,500–13,500
