Based on field experience from operators running identical units, this cement silo comfortably holds 8–9 standard pneumatic tanker loads of cement or fly ash while maintaining appropriate working headroom.

Actual capacity will vary based on material density and fluff factor. Ten full tanker loads would bring material level very near the top with minimal air space, so 8–9 loads represents a practical operating range.

Discharge & Feeder Configuration

  • WAM Rotary Vane Airlock Feeder

  • Motor installed

  • Bottom-mounted blow-through adapter beneath feeder

  • Pneumatic discharge piping in place

Note: The supplied WAM feeder did not include an integrated blow-through component. A bottom-mounted blow-through adapter has been installed beneath the rotary feeder. Buyers may utilize the current configuration or modify discharge components to suit plant preference.

Optional Add-Ons (Quoted as Requested)

  • High-level bin indicator system

  • Pressure Relief Valve (PRV)

  • Sandblast and repaint to buyer-selected color

FAQ

What Is the Actual Storage Capacity of the Vertical Pneumatic Cement/Fly-Ash Silo? +

The Vertical Pneumatic Cement/Fly-Ash Silo has an approximate capacity of 5,250 cubic feet, which equals roughly 1,310 barrels or approximately 247 short tons when storing cement at standard density (94 lb/ft³). This capacity makes it suitable for medium to large-scale concrete production operations. The vertical design maximizes storage volume while minimizing ground footprint.

What Materials Can a Vertical Pneumatic Cement/Fly-Ash Silo Store? +

This Vertical Pneumatic Cement/Fly-Ash Silo is configured for cement and fly-ash storage. After the current conversion is complete, it will handle Portland cement, fly ash, slag cement, and similar powdery cementitious materials. The pneumatic discharge system and rotary vane feeder are specifically designed for fine, dry bulk materials. It is not suitable for aggregates, sand, or moisture-sensitive materials without additional modifications.

What is the WAM RVN20201A00 rotary vane feeder? +

The WAM RVN20201A00 is a 12-inch by 12-inch square opening rotary vane feeder that operates at 20 RPM. It features Vulkolan plastic tips on the rotor blades for durability and consistent material flow. This heavy-duty feeder provides reliable, controlled discharge of cement from the silo into pneumatic conveying lines or directly to batching equipment. WAM is a globally recognized manufacturer of bulk material handling equipment.

What work is being done during the conversion? +

The silo is being converted from bulk sand storage to cement/fly-ash service. The conversion includes: installation of a new 12-inch slide gate with hand wheel, integration of the WAM RVN20201A00 rotary vane feeder with motor, addition of pneumatic blow-through discharge components, and installation of a new pressure relief valve (PRV). This conversion ensures the silo meets all requirements for safe cement handling.

When will the silo be ready for delivery? +

The conversion work is scheduled for completion by mid-December 2025. The silo will be fully upgraded, tested, and ready for cement operations at that time. Buyers can arrange delivery or pickup once the conversion is complete. Additional upgrades or customization requests may affect the timeline and should be discussed with the seller.

What is the structural condition of the silo? +

The silo is structurally solid with only one small cosmetic dent on the top section that does not affect operational performance. The main body, cone, legs, and support structure are in good condition. The silo is approximately 10 years old (manufactured in 2015) and has been well-maintained. The dark green exterior color is original, with optional repainting available.

How does the pneumatic discharge system work? +

The pneumatic discharge system uses compressed air to fluidize cement at the bottom of the silo, allowing it to flow into the rotary vane feeder. The feeder meters material into a pneumatic conveying line where additional air carries it to the destination. This “blow-through” configuration is ideal for conveying cement over distances up to several hundred feet. The system requires a consistent air supply at appropriate pressure.

What are the power requirements? +

The rotary vane feeder motor is a WAM part MT1450C06W46 (available as Baldor or WAM brand). This typically requires 460V three-phase power, though specific voltage can be confirmed. Additionally, you’ll need compressed air capability for the pneumatic system, typically 80-120 PSI at sufficient CFM for your discharge rate. The exact air compressor size depends on conveying distance and production demands.

How quickly can this silo discharge cement? +

Discharge rate depends on several factors including air pressure, conveying distance, and feeder speed. The 12×12 rotary feeder at 20 RPM can handle substantial throughput, typically in the range of 20-40 tons per hour under normal operating conditions. Actual rates vary based on your specific pneumatic system configuration and cement characteristics. The large opening size ensures consistent flow without bridging.

How is the Vertical Pneumatic Cement/Fly-Ash Silo transported and installed? +

The Vertical Pneumatic Cement/Fly-Ash Silo is located in Graham, Texas. The seller mentions that freight with offloading and uprighting can be arranged without requiring a crane using specialized trailer equipment. This is a significant advantage, as traditional silo installations typically require large mobile cranes. The vertical silo can be transported horizontally on a flatbed and then hydraulically raised into position on-site.

What foundation is required? +

A concrete foundation is required to support the silo’s four legs. The foundation must be level, properly reinforced, and include embedded steel plates for welding or bolting the silo legs. Foundation specifications depend on soil conditions and total loaded weight (silo plus approximately 247 tons of cement). A qualified structural engineer should design the foundation based on your site conditions. Browse our complete selection of concrete batch plants for sale to compare different capacity options for your project needs.

Does installation require special equipment? +

While the seller offers crane-free installation using specialized equipment, you’ll still need standard rigging equipment, welding equipment for securing legs to the foundation, and equipment to connect pneumatic lines, electrical conduit, and the discharge system to your batching plant. The conversion includes all major components, but you’re responsible for integrating it into your existing facility.

What regular maintenance does this silo require? +

Regular maintenance includes: cleaning or replacing the top-mounted dust collector filter (monthly to quarterly depending on usage), inspecting and lubricating the screw conveyor system if present, checking the rotary feeder for wear on Vulkolan tips (annually), verifying the pressure relief valve operates correctly, monitoring material level sensors, and inspecting seals around fill pipes and manholes. The pneumatic aeration system should be checked periodically for proper airflow. Click here to share on your social media platforms.

How long do rotary feeder components last? +

The Vulkolan tips on WAM rotary feeders are known for durability. Under normal cement handling conditions, tips can last 3-5 years or longer before replacement is needed. The feeder motor and bearings require standard maintenance per manufacturer specifications. WAM provides excellent parts support, and replacement components are readily available through industrial equipment suppliers nationwide.

What Optional Upgrades Are Available for Vertical Pneumatic Cement/Fly-Ash Silos? +

The seller offers several optional upgrades including: sandblasting and repainting in your preferred color, high-level bin indicator system for automated monitoring, additional fittings such as reducers and elbows for pneumatic connections, custom piping configurations, and specialized freight/installation services. These upgrades can be quoted individually based on your specific requirements and preferences.

Vertical Pneumatic Cement/Fly-Ash Silo Additional Notes

Safety Compliance: The new PRV (pressure relief valve) is a critical safety component that prevents over-pressurization during pneumatic filling. Always ensure delivery truck operators are trained in proper silo filling procedures.

Material Flow: Cement silos should be kept as full as practical to maintain proper material flow and prevent moisture absorption. The pneumatic system’s aeration keeps cement fluidized and prevents bridging or rat-holing.

Inspection Opportunity: Buyers are encouraged to inspect the silo in Graham, Texas before or after the conversion is complete. Contact the ConcreteIron Concierge at 817-837-9812 to schedule a viewing.

Price: Listed at $84,500 USD, this represents excellent value for a fully converted, operational-ready cement silo with premium discharge equipment included.
