VersiFeeder
Volumetric Screw Feeder
Modular Design
The Vibra Screw VersiFeeder is the first volumetric feeder with modular design, enabling a single unit to adapt to the broadest range of feeding applications.
- A Standard Feeder, with static hopper, trough and feed screw for free-flowing materials.
- An Agitator Conditioner Feeder, with secondary trough conditioning screw for semi-free flowing materials.
- A Vibrated Feeder, using Vibra Screw’s controlled vibration design for non-flowing materials.
The VersiFeeder permits selection of the most economical design required for a specific application, with the unequaled ability to upgrade the design as materials or characteristics change. You’ll always achieve accuracies of ± 1-2% whether with pellets, flakes, powders or fibers.
Standard or Sanitary from 0.14 to 600 ft3/hr
The VersiFeeder is available in screw sizes from 1” to 6” and sanitary construction in all sizes. Whether you feed chemicals, foods or pharmaceuticals, VersiFeeder’s wide range of models and options meet the need.
Easy Clean, Tool-Less, Rear Seal Removal
The Vibra Screw VersiFeeder offers optional rear screw removal, permitting cleaning and screw size changes away from the process side. Disassembly is accomplished without tools and in a mater of minutes. All driveline components, gaskets and seals maintain their alignment and integrity during disassembly and reassembly. The screw can also be removed from the front if desired.

VOLUMETRIC FEEDER FOR FUMED SILICA
Fumed silica also known as pyrogenic silica because it is produced in a flame pyrolysis of silicon tetrachloride or from quartz sand vaporized in a 3000 °C electric arc. Fumed Silica consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles. The resulting powder has an extremely low bulk density […]
