Introduction
Aeration Pad System for Flat Bottom Silo Material Fluidization
Aeration Pad System for Flat Bottom Silos
Fine powders stored in flat bottom silos compact under their own weight, forming a dense, impermeable bed that resists gravity discharge. Our aeration pad system introduces low-pressure air through porous media embedded in the silo floor, fluidizing the material into a semi-liquid state that flows freely toward the discharge outlet.
How Aeration Pads Work
Sintered stainless steel or ceramic porous elements are recessed into the silo floor in a carefully designed pattern. Compressed air (0.2-0.5 bar) passes through the porous media, creating a thin air film on the material surface. This reduces the effective friction between particles, allowing gravity to pull the material downward and outward.
Design Parameters
| Parameter | Cement | Fly Ash | Hydrated Lime |
|---|---|---|---|
| Air pressure | 0.2-0.3 bar | 0.15-0.25 bar | 0.1-0.2 bar |
| Air volume | 0.3 m³/min/m² | 0.2 m³/min/m² | 0.15 m³/min/m² |
| Pad coverage | 60-80% of floor | 50-70% | 70-90% |
Key Benefits
- Eliminates ratholing and bridging in flat bottom silos
- Reduces discharge energy consumption by 60% vs. mechanical extractors
- No moving parts in the aeration system—minimal maintenance
- Compatible with all fine powders (D50 < 100 microns)
