Facilitating powder extraction under silos

Composed of a steel or stainless steel cone, weld-free construction, integrated flange joint on top and bottom, silo connection brackets, and one or two electric vibrators. The unloading section must have a large diameter. A flange is welded to the silo cone. Special brackets and a technical polymer gasket form a flexible connection between the silo and the bin activator : one or two electric vibrators are mounted at the bottom on the side and vibrate the entire bottom, without vibrating the silo above it.

During extraction, the bin activator performs a circular movement which is transmitted to the material inside the silo and therefore provides for uniform flow. Using this system optimizes material extraction with excellent mass flow and reduces the formation of bridges and mouse holes.

Main advantages

• Mechanical extraction without air or vibration and therefore without pollution or settling
• Fitting under the silo with a simple flange
• Works independent of load with full silo emptying
• Low installed power
• Sealed, silent operation
• Easy to install: losose flange, adjustable length, flexible or rigid feeder
• Quick assembly
• Easy recovery or transfer module adaptation
• Independently operating dual feeder
• Reduced floor space required
• Limited silo ground clearance
• Accurate extraction whichever quantity of powder remaining in the silo
