Vibra Screw - Bin Activators and Heavy Duty Bin Dischargers for Dry Bulk Material Handling

SHARE
Vibra Screw offers specialized equipment for the movement and discharge of dry bulk materials from silos and bins. Their legacy began with the invention of the Bin Activator over six decades ago. These activators are crucial in preventing common flow issues like bridging and ratholing, ensuring consistent mass flow. The company provides three main designs: the Dished Head, Model HDBD with a compound slope body, and the rolled cone Bin Discharger. The Heavy Duty Bin Dischargers, designed for larger silos, combine an upper shallow section with a steep lower cone, eliminating packing and bridging without secondary baffles. Noteworthy features include a robust forged steel suspension system with elastomer isolators to minimize vibration transfer, patented beaded sleeves that resist leakage and withstand pressure, and a choice of oil or grease-lubricated vibrators designed for long service life. These products cater to a wide range of industries handling some of the most challenging materials.

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 65 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.

Vibra Screw has introduced a line of Heavy Duty Bin Dischargers for large silos. These machines offer the advantages found only in Vibra Screw’s patented dished head Bin Activators at lower cost.

The Heavy Duty Bin Dischargers combine a shallow upper section with a steaper lower cone. This compound shape eliminates bridging and packing at the discharge outlet that is common with single sloped designs. No secondary baffles required.

Heavy Duty Bin Dischargers are available in diameters from 6’ to 12’. Heavy Duty Bin Dischargers use the same flexible sleeve, vibration isolation system and vibratory drives as Vibra Screw’s Bin Activator so existing customers will find complete compatability in fit up and spare parts inventory
