Bulk Bag-Closing Device Stops Partial Discharges

Pneumatically operated device uses dual blades versus pinching devices to seal the opening Quick sealing capability Effective for fluidized dry materials Seals materials against humidity

Unlike slide gates (which push bags off to one side) and heavier, more expensive knife gates, butterfly valves, or rope closures, the pneumatic device provides a simple, safe and dust-free means to seal bags.

VIBRA SCREW INC., a manufacturer of equipment and systems for precision processing of dry bulk materials, is offering a new bulk bag-closing device designed to quickly and safely stop flow from partially discharged bulk bags. The lightweight, pneumatically operated device uses dual blades rather than pinching devices to seal the bag opening more effectively at the center, so an operator can tie it off for removal. Unlike slide gates — which push bags off to one side — and heavier, more expensive knife gates, butterfly valves, or cruder rope closures, the pneumatic device provides a far simpler, safe and dust-free means to seal bags.

The device’s quick-sealing capability is particularly effective where fluidized dry materials such as calcite, alumina or bentonite are handled, or materials that do not normally have fluid characteristics become fluid after aeration or during discharge from storage.

The device is also effective in preventing plant humidity from reaching hygroscopic materials during discharge, during the closing procedure, or during idle time in the process cycle.

Vibra Screw systems use controlled vibration to condition and drive bulk materials into and through a process. It manufactures bin activators, bulk bag unloaders, volumetric screw and belt feeders, and all types of gravimetric feeds, blenders, and controls.
