The "Vicon" Vibratory Discharger (or "Bin Activator") has been designed to provide a cost effective method of discharging powders or granules from storage silos and bins. A vibrating motor is attached to a transition hung from vibration isolation arms attached to the silo - this vibrates the product, not the silo.
For positive, continuous flow of almost any material, a vicon discharger is unmatched. It mounts under any existing round or square silo, whether concrete or steel. Vicons promote the steady flow of granular or powdered material from storage bins, hoppers or silos. They are designed to prevent bridging, jamming, clogging, compacting and rat-holing. Vicons are made of stainless steel or carbon steel and mount directly to material handling equipment. Most products include a unitized vibrator or gyrator that moves dry material toward a narrow opening on a first-in, first-out basis. Cone-shaped, dish-shaped, or multi-sloped baffles promote mass flow and reduce particle segregation. To prevent slippage or leakage, a heavy-duty sleeve can be attached with steel clamps or bolts. In some cases, vibratory bin activators are used in conjunction with aerators or bin fluidizers, devices which inject air along an internal area of the bin to break up bridges or arches in bulk material.
When a bin or silo is filled, the fines usually end up in the middle with larger particles on the periphery. GEA Nu-Con Vicons allow material to flow under the head from the outer portion of the tank, while also allowing the core or center of the material to flow over it and into the discharge. As a result the fines mix with the larger particles to create a more uniform mix.
