Bin activator

By Wayne Labs, Senior Contributing Technical Editor

Spiroflow Systems’ adjustable bin activator controls the discharge of powders and granules. Whether the material comes from a silo or a bulk material handling system, the activator alleviates material bridging while controlling flow rates. The unit promotes material flow via vibration and regulates the flow of solids with blades that close quickly. The activator’s feeder has blades that are fully adjustable for accurate and repeatable control of solids flow. Energy is imparted directly into the solids by the vibrating blades to maintain flow; the discharger control valve provides close tolerance blades for positive shut off of solids flow.
