Bin Activators | Vibrating Bin Discharger | Polimak

Bin Activators are equipment conically shaped that aid dry bulk material flow from storage silos, or hoppers. Polimak Bin Activators are used in several industrial applications to efficiently discharge dry solid materials in powder or granular form from upstream equipment, thereby, reducing bulk material bridging or ratholing while promoting mass flow.

Bin Activator Key to Efficient High-Rate Loss-in-Weight Feeding

In addition to promoting flow, the bin activator deaerates material, bringing it to a uniform density. The bin activator is suspended from the storage bin by forged steel hanger arms fitted with elastomer bushings. This provides great vertical strength while isolating almost all the vibration from the storage bin.
