Bin activators are used to promote reliable material discharge from bulk material storage. They are mounted to the bottom of hoppers and silos via hanging arms. When switched on, they pass vibration to the stored material reducing the potential to bridge, rat hole or segregate.
Applications for bin activators include:
- Material is sticky and binds.
- Material is wet or becomes wet during storage.
- Material has a tendency to bridge, rat hole or segregate.
- Reliable flow is a necessity.
Vibratory feeders are usually installed together with bin activators to assist in material withdrawal from storage. Proper interfacing is critical to ensure that material flows optimally.
Electronic controls and timers are used with great effect in bin activators. Ideal operation duration and delays can be established through trial and error and programmed either prior or post material withdrawal.
Trough construction is generally from mild or stainless steel. Wear resistant materials such as bisalloy or hardox are also be used.
Liner options are numerous:
- Polyurethane based liners can be used to protect the trough and prevent material build up.
- Hardox or bisalloy liners can provide wear resistance.
- Teflon can be sprayed on the trough surface to give a smooth non-stick surface.
- Rubber can be attached either fully or partially to provide a live, slipper surface.
