Silo & Bulk Material Handling
Fine dry powders stored in tall silos tend to compact, bridge, and rat-hole, preventing consistent gravity discharge. SAE Roots blowers supply aeration air to fluidizing cones, canvas pads, and air slides, transforming compacted bulk powders into free-flowing, fluid-like streams for rapid loading into bulkers and conveyors.
Critical Engineering & Design Requirements
- Moisture-Free & Oil-Free Air: Moisture or oil causes powders to cake instantly on fluidization cloths, causing system blockage.
- Stable Air Pressure: Overcomes the hydrostatic head of stored bulk powder up to 30 meters high.
- Compact Footprint: Easily mounted beneath silo skirts or in adjacent auxiliary utility rooms.
Engineering Selection Advice
Incorporate an air drying unit or desiccant dryer in high-humidity zones to prevent hygroscopic powders from clogging fluidization membranes.

Frequently Asked Questions – Silo & Bulk Material Handling
Q:How does silo fluidization work?
Air injected through porous aeration pads aerates compacted powder particles, reducing friction and allowing the powder to flow freely out of the discharge valve.
Q:Can one blower supply multiple silos?
Yes, with appropriate manifold piping and motorized butterfly valves, a single SAE blower package can sequentially fluidize multiple silo banks.
