Vibra Screw Heavy Duty Screw Feeders

Vibra Screw Heavy Duty Screw Feeders
24 Feb 2022  |

Vibra Screw Heavy Duty Screw Feeders are extremely versatile. One unit can precisely meter many different materials with little or no adjustment. When necessary, adjustments can be made quickly and easily. Screws and tubes can also be changed on some models for a wider range of feed rates. All feeders are fabricated of high-strength steel and contain only a few moving components. They are built to operate continuously with only a minimum of maintenance.

Unique Operation

Because maximum feed accuracy is dependent upon positive material flow from storage, we designed these Heavy-Duty Screw Feeders for use beneath bulk storage hoppers. Hoppers that pack or bridge should be equipped with a Vibra Screw Bin Activator to ensure consistent material flow to the feeder.

In operation, the feeder trough, screw, and tube are subjected to continuous controlled vibration. This permits the material to move gently from the upper section of the trough to the feed screw without bridging, packing, or flooding. Vibration further conditions the material to a constant bulk density and ensures that each flight or pitch of the screw is filled to its maximum in the filling area and completely emptied at the discharge end. The positive displacement of material is further ensured through the use of a rotating solid flight screw.

Rugged construction to operate 24 hours a day, Vibra Screw’s line of volumetric Heavy Duty Feeders will meter even the most difficult materials in an extremely reliable manner. A patented controlled vibration principle ensures exceptional accuracy of ± 1%, minute to-minute. A wide variety of products, from long fibers to micron-sized particles, and materials with bulk densities ranging from 2 to 200 lb/ft3 can be successfully handled with precision. Available is screw sizes from 2” to 16” with feed rates from 2.3 to 9,800 ft3 /hr.

As with all Vibra Screw equipment, the Heavy-Duty Screw Feeder is unconditionally guaranteed to perform in the service for which it is sold. With a staff of experienced and talented engineers, technicians, and craftspeople, Vibra Screw manufacturers high-quality equipment to store, discharge, meter, convey, size and blend solid materials. The company’s comprehensive product range includes Bin Dischargers, Bulk Bag Unloaders and Fillers, Volumetric and Gravimetric continuous and batch feeders, Vibration Conveyors, Vibrating Screeners, Blenders, Process Controls and Turnkey systems.
