In many cement silos, fine powder material tends to cling or hang-up in the hopper or cone area, leading to uneven discharge or blockages. An air pad is installed on the inner cone wall and creates a thin air cushion that reduces friction and supports smooth material movement. This improves discharge reliability and reduces manual cleaning.

WorkIng PrIncIple

When the silo air pad is activated, compressed air is distributed beneath a perforated or porous membrane section integrated into the cone surface. This air cushion reduces contact between the material and the silo wall, enabling the material to slip and flow downwards under gravity. Over time this reduces build-up and promotes free flow.

Advantages & Features

* Enhances silo discharge speed and reliability.
* Low energy consumption compared to vibration systems.
* Minimal maintenance since no moving parts inside the material zone.
* Suitable for fine cement powders and fillers in storage silos.
