Bin Activators

Do you need to effectively control the discharge of material from bulk containers? Bin activators can control material flow rates and minimize bridging.

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.  Spiroflow bin activators are offered in 12″/ 305mm & 24″/ 610mm sizes as well as custom sizes.

Features

HOW IT WORKS

Feeder

The blades are fully adjustable for accurate & repeatable control of solids flow.

Activator

Energy is imparted directly into the solids by the vibrating blades to maintain flow.

Discharge Control Valve

Close tolerance blades provide positive shutoff of solids flow.
