Pneumatic (fluidization) systems use pressurized air to make fine powdered materials (especially cement, ash, lime) flowable, ensuring regular and continuous discharge from the silo.
Purpose: Prevent bridging, rat-holing, and clogging while ensuring smooth flow from the conical silo outlet.
Key Features:
Pressurized air improves material flowability
Prevents clogging and bridging
Highly effective for fine powders
Can be used with screw conveyors or valves
Commonly used for cement, ash, and fine mineral powders
Air pads, jet nozzles, or aeration plates at the silo cone introduce low-pressure air
Air penetrates material particles, reducing internal friction
Powder becomes semi-fluidized and flows under its own weight
