New Bulk Bag Closing Device Stops Material Flow

This new bulk bag closing device is designed to quickly and safely stop flow from partially discharged bulk bags. The lightweight, pneumatically-operated device uses dual blades vs. pinching devices to more effectively seal the bag opening at the center so the operator can tie it off for removal.

Unlike slide gates that 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 sealing 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.
