limestone silo for sale
A limestone silo is a closed steel silo specifically designed for storing limestone powder or limestone particles. As a global supplier with over 20 years of experience in manufacturing steel silos, AGICO offers you a one-stop service from design, manufacturing, installation, to after-sales. Our silos have capacities ranging from 200 tons to 50,000 tons and can be customized. Welcome to inquire about a quote.
Types of limestone silo we supply:
- Hopper silo: Has a big cone angle (≥55°) at the bottom, with devices to stop blocking and help smooth discharge.
- Spiral steel silo: Very good sealing. Keeps out air and moisture to stop lime from getting wet.
- Bolted silo: Has anti-corrosion coating inside, for long life.
- Welded silo: Used for labs or special chemical needs.
AGICO Customized Steel Silo Systems with Turnkey Solutions.
Structure of limestone silo
Main body of the silo
It adopts a spiral lock seam steel plate structure, which is of high strength and good sealing performance.
Discharging system
A gasification device, arch-breaking device, or air slide conveyor is set at the bottom to ensure smooth discharge of materials.
Measurement and control system
Level gauges, pressure sensors, and temperature and humidity monitors are used to monitor the status inside the silo in real time.
Dust removal system
A bag filter or pulse dust removal system is installed on the top of the silo to prevent dust from escaping.
Safety system
It includes explosion-proof valves, arch breakers, safety ladders, and maintenance platforms.
Advantages of limestone silo
Sealing
The sealing grade can reach a 0.1mm air-tightness standard, ensuring excellent moisture-proof performance in high-humidity or coastal areas. Double-layer sealing gaskets and waterproof tapes are added at key positions, such as the top and bottom of the silo and inspection ports, to prevent the intrusion of external moisture and rainwater effectively.
Smooth Discharge
In the structural design, AGICO adopts an optimized cone angle (generally 45° to 60°) and installs air or vibration arch breakers at the bottom of the silo, increasing the stability of continuous discharge by over 30% and ensuring uninterrupted supply to the production line.
Short Construction Period
AGICO’s steel silos are constructed using a factory prefabrication and on-site assembly method. Main components such as silo walls, cone bottoms, top covers, ladders, and railings are all standardized modules. Compared to traditional concrete silos, the installation speed is increased by 40%, and labor costs are reduced by approximately 25%.
High-Efficiency Dust Removal
The top of the silo is equipped with a pulse bag filter or cartridge filter, which is environmentally friendly and energy-saving, meeting ISO and EU environmental protection standards.
Higher Returns
Steel silos can be disassembled, relocated, or expanded after use, offering high flexibility and reducing repetitive investment. The payback period is short, with construction costs recovered in just 1.5 to 2 years.
Corrosion Resistance
The exterior of the silo can be coated with an epoxy zinc-rich primer + polyurethane topcoat anti-corrosion system, providing a protective life of over 30 years. The standard service life is ≥ 30 years, and the anti-corrosion grade can reach C4-H.

Solutions of limestone silo
The limestone silo can be applied in many places, such as the desulfurization system of power plants, where it is used to store limestone powder for the preparation of desulfurization slurry; cement production lines, where it stores limestone powder as raw material or blending component; lime production lines, where it stores limestone to be calcined; the metallurgical industry, where it stores furnace feed limestone particles; and the chemical industry, where it stores calcium carbonate powder.
AGICO Limestone Silo vs Other Brands
| Comparison Item | AGICO (China) | Schenck Process (Germany) | SRON Silo (China) |
|---|---|---|---|
| Silo Structure Design | Uses spiral folded plate technology – no welding seams, excellent strength and sealing | Traditional welded structure, strong but complex to build | Basic welded structure, more seams, easy to leak |
| Material Quality | High-strength galvanized steel (275g/m² zinc layer), optional stainless steel | Quality carbon steel, medium anti-corrosion | Regular carbon steel, thin zinc coating |
| Anti-Corrosion Life | Up to 30 years with double-layer protection + epoxy coating | About 25 years | 10–15 years |
| Moisture & Sealing Performance | Spiral tight-sealed joints + waterproof sealing rings | Welded seams with sealant | No waterproof design, easily absorbs moisture |
| Anti-Arching Design | Optimized cone angle (45°–60°) + air blasters + aeration pads | Simple vibrating discharger | Vibrating motor only |
| Dust Collection System | Pulse-jet bag filter on silo top, 99.9% efficiency, ≤20mg/m³ emission | Cartridge filter system | Simple dust collector or external device |
| Automation & Control | PLC control system, automatic level, pressure, and humidity monitoring | Semi-automatic PLC | Manual or semi-auto control |
| Installation Method | Modular assembly or lifting installation, prefabricated for fast setup | On-site welding, slow installation | Manual welding, low efficiency |
| Installation Time (for 1000t silo) | 15–25 days | 35–45 days | 40+ days |
| Construction Cost | 35–45% lower than concrete silos, lower shipping and labor cost | High (Europe labor & logistics) | Lower, but quality not stable |
| Maintenance Cost | Very low – only regular inspection needed | Moderate | High – needs frequent repainting |
| Environmental Standard | Meets ISO14001 & EU emission standards | Meets EU standards | Below EU standards |
| Service Life | 30+ years | Around 25 years | 10–15 years |
