Bin Activators

For controlled discharge of material

When you need to control material flow rates and minimize bridging consider the Spiroflow Bin Activator.  The feeder blades are fully adjustable for accurate and repeatable control of solids flow.  Energy is imparted directly into the solids by vibrating blades to maintain flow.

The close tolerance blades provide positive shut-off of solids flow.  Offered in 12" (5 cm) & 24" (60 cm) sizes as well as custom sizes.
