Today’s process industries most often rely on Bin Activators to move dry bulk materials out of storage, on demand. Properly applied, Bin Activators eliminate bridging and ratholing, reduce particle segregation and promote mass flow. They are efficient, convenient and economical and attach to any bin or silo whether new or existing.

Because we invented the Bin Activator almost 50 years ago and continue extensive research into bin flow problems and solutions, Vibra Screw offers you an uncommon range of experience.

There are more Vibra Screw designed Bin activators in service today, than all others combined, handling some of the most flow resistant materials.

All material handling systems begin with a thorough review of the particulate solid(s) being handled or processed. Once the flow properties of a solid are quantified, flow problems that occur with a given material can be predicted and handled, preferably in the initial design stage. Understanding a material’s characteristics and how to apply these properties is essential for a safe, efficient and trouble free system.
