Engineered to stop flow from partially discharged bulk bags, the bulk bag closing device from Vibra Screw uses dual blades instead of pinching devices to seal the bag opening at the center. Lightweight and pneumatically operated, the device is particularly effective for fluidized dry materials such as calcite, alumina or bentonite, or materials that do not normally have fluid characteristics that become fluid after aeration or during discharge from storage.
