coal storage silo
In the past, coal was mostly stored in open areas. However, this would reduce the value of the coal and also cause environmental pollution. The AGICO coal silo meets the requirements of automated production for coal enterprises, completely preventing the spread and pollution of coal dust. It has also reduced operating costs. The AGICO steel silo is the preferred choice for many enterprises.
- Sturdy structure
- Strong corrosion resistance
- Short construction period
- Service life can reach 30 years

Advantages of AGICO coal silos
The AGICO coal storage silos are constructed quickly, at a low cost, with features of explosion-proof, fire-proof, and self-ignition prevention. It can store a large volume of materials and is suitable for energy and heavy industry projects. AGICO manufacturer is favored by many customers worldwide. Here are the specific advantages of AGICO’s coal storage silos.
Large capacity
AGICO steel silos are strong. One silo can store from a few hundred tons to tens of thousands of tons. We have two types of discharge: flat bottom silo and hopper bottom silo. Extra equipment, like vibrators and air cannons, helps coal flow smoothly.
Explosion-proof and fire-proof
AGICO coal silos are very safe. The coal storage silo roof and walls have pressure release doors, temperature checks, and gas sensors. Nitrogen or other safe gases can be added to stop coal dust explosions or fire.
Dust and moisture protection
AGICO coal silo is well sealed. Welding or bolts stop air from coming in, so coal does not catch fire by itself. Dust collectors at the outlet reduce air pollution.
Monitoring and control
The coal silo connects to conveyors and loading systems. It works with automatic control. It has level meters, temperature sensors, and gas monitors to check inside in real time.
Insulation
The silo wall has 80–100 mm insulation. It keeps coal from losing water in winter and makes transport easy.
Many discharge types
AGICO coal silos can have 1, 2, 4, or 9 discharge ports. Small coal silos usually use cone discharge. The cone wall is steep (over 45°). The inside wall has a smooth stone coating, allowing coal to flow more easily.
Types of coal silos
spiral steel silo
flat bottom silo
bolted steel silo

workflow of coal storage silo
The following is the working process of the coal silo. A complete coal silo system consists of the feeding system, dust removal system, pneumatic conveying system, silo body, electrical control system, base frame, guardrail, and other components.
The powdered materials are conveyed from the feed pipe to the coal silo. Either raw coal or fly ash can be directly sent into the silo by a bulk material truck.
At the bottom cone of the silo, there is an air blowing arch-breaking device. The release of compressed air is controlled by a small electromagnetic directional valve in the pneumatic box, which helps break the coal powder arch and prevent blockages.
The top of the coal silo is equipped with a level sensor, and radio frequency capacitive level limit switches are installed at the top and bottom of the coal silo, respectively. When the switch is closed, we can sense the height of the material level inside the silo through electrical signals, thereby analyzing the inventory of coal powder or other powders.
An electric dust removal device is installed at the top of the coal silo, which can reduce the emission of coal dust into the surrounding environment. When the accumulated dust on the top of the dust collector reaches a certain level, the electrical control will activate the vibration motor to shake the dust off.
If you need to customize according to the actual situation of your factory, AGICO has globally leading design experts. Our team can conduct a professional design to meet any of your requirements.
Coal silo VS concrete silo
The commonly used coal storage silos include concrete silos and steel silos. If you are considering using concrete silos to store coal powder and coal blocks, then I suggest you re-examine the value of steel silos.
Compared with concrete silos, coal silos are more economical and practical, and have features such as a beautiful appearance, excellent construction quality, and a short construction period. AGICO steel silos are more in line with the requirements of safety, sealing, explosion prevention, and no blockage.
| Item | Coal Silo | Concrete Silo |
|---|---|---|
| Build Time | Built with steel plates. Finished in weeks. | Made with concrete. Takes months to build. |
| Cost | Cheaper. About 60%–70% of concrete silo. | More expensive, huge silos. |
| Capacity | From hundreds to tens of thousands of tons. Easy to change or add. | Fixed size. Hard to expand. |
| Safety | Has explosion vents, a gas check, and a nitrogen system. Stops fire and coal dust blast. | Mostly for grain or cement. Not safe enough for coal. |
| Dust Control | Sealed body with a dust collector. No coal dust outside. | Weak dust control. Not good for coal dust. |
| Maintenance | Easy to repair. Can add wear plates. Life 30+ years. | Hard to repair cracks. Repair costs are high. |
| Discharge | Cone bottom + vibrator/air cannon. Coal comes out smooth. | Works for powder. Coal may block. |
| Weight and Space | Light and strong. Small land needs—modern look. | Heavy. Needs a strong base. Takes more land. |
| Use | Best suited for coal-fired power, steel, and chemical plants. | Good for grain, cement, or fly ash. Not for coal. |
All in all, this is the conclusion of the core advantages of coal silos.
- More economical: Lower construction cost, shorter construction period, and quicker return on investment.
- Safer: Explosion-proof, fireproof, and fire-retardant. Designed specifically for coal characteristics.
- More flexible: Capacity can be large or small, and expansion is convenient.
