Vibra Screw, Inc., a leading manufacturer of equipment and systems for precision processing of dry bulk materials, is offering a new bulk bag closing device designed to quickly, 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 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 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 highly 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 introduced the concept of controlled vibration to condition and drive bulk materials into and through a process more than 40 years ago. Today they manufacture the broadest line of equipment incorporating this feature including bin activators, bulk bag unloaders, volumetric screw and belt feeders, and all types of graimetric feeds, blenders, and controls.

Vibra Screw, Inc., a leading manufacturer of equipment and systems for precision processing of dry bulk materials, offers a series of pan and tube conveyors designed to provide a simple and efficient means to meter and convey dry bulk materials.Designed to economically feed powders, flakes or agglomerates without dust or degradation, the pan and tube conveyors feature two highly efficient, externally mounted vibrators that provide a unidirectional vibratory motion along the conveyor axis in constant or variable operation. Flow rates are adjustable by resetting the eccentric force during operation or with an optional speed controller. With no screws, drag chains, bearing seals or other internal moving parts, the units require little or no maintenance and are ideal for sanitary applications.Individual units are available in lengths up to 25 feet, connectable in series up to 100 feet and offer capacities in both open pan or closed tube arrangements up to 36,000 cu/ft/hr. A variety of troughs, screws and control options are available along with designs for screening, dewatering or elevating.Vibra Screw introduced the concept of controlled vibration to condition and drive bulk materials into and through a process more than 40 years ago.
