Bin activator

‹‹ ››

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. normes atex certified palamatic process

Main advantages
