Vibrating cone (bin activator)
A vibrating discharge system that empties hard-to-flow powders and granules from silos evenly and without interruption.
Ideal application: For food, chemical, plastics, cement, mining and building materials plants, to discharge poorly flowing, moist, fine or caking materials from silos and hoppers.

Key features
- Steady feed to screw conveyors, rotary valves and gates below by reducing bridging and blockages
- Internal baffle balances the material load and transfers vibration effectively into the material
- Sealed flexible sleeve helps prevent dust leaks and isolates vibration from the silo shell
- Shock-absorbing suspension with rubber and steel elements protects the silo structure
- Runs only during discharge, avoiding unnecessary energy use
- Connection design suited to silo and hopper outlets for easy retrofit
Also called a silo vibrating bottom, the bin activator is mounted under the silo or hopper on flexible connections and driven by a vibrator motor.
With moist, sticky or caking materials it reduces bridging, rat-holing and packing, so material flows evenly across the full silo cross-section.
