Vibratory Feeders

Vibratory feeders for fragile, friable, abrasive or difficult materials such as fiberglass

Coperion K-Tron's vibratory feeders are best for feeding fragile ingredients and problem materials such as fibers, glass fibers and abrasive materials such as rough-grained powders and granules.

Vibratory feeders provide excellent gravimetric feeding of very free flowing bulk materials such as granules and coarse powders. They are especially well suited for abrasive products.

Vibratory trays are available in three sizes and can be combined with various hopper sizes. All parts in contact with the material being fed are stainless steel. Modular models are designed to allow easy interchange of the hopper, drive, or even another type of feeder module such as a single-screw or twin-screw metering device.

Where uniform discharge is critical, especially at very low rates, Coperion K-Tron’s patented 3-loop loss-in-weight vibratory feeders provide the best solution.

One control loop maintains tray resonance, a second loop varies amplitude to control rate, and a third loop reflects the mechanical dynamics associated with the unique combination of material and feeder to trim output to the highest attainable accuracy.

Fiber Feeder Models

Vibratory fiber feeder models are especially suited for feeding glass fibers with lengths of 3 to 6 mm. Coperion K-Tron has designed a vibratory tray fiber equalizer for accurate and reliable feeding of glass fibers (or other fibers). The fiber equalizer is adjustable for different configurations to match feed rate and behavior.

The totally enclosed channel prevents fiber contamination of the surroundings. Due to the efficient function of the equalizer the vibrating tray is very short in length.

Vibratory Pharmaceutical Feeders

A pharmaceutical model, available in volumetric and loss-in-weight configurations, is designed for difficult flowing pharmaceutical powders.

Vibratory Drive Designed for Feeders

The Coperion K-Tron vibratory drive is part of the control system and has been developed especially for use with feeders.

A main design feature of the drive is the large weight difference between the stationary and moving components. The leaf spring being tension free when not in operation can be easily replaced.

The electronic control system provides a quick response to changing feed and environmental conditions. The control feedback signal is produced by means of a permanent magnet and spool.

Design Features:

  • Few parts
  • Maintenance free: no mechanical parts and joints that could wear
  • Vibrating Tray: Three sizes depending on feed rate
  • Fiber feeders include adjustable fiber equalizer in different configurations to match feed rate and behavior
  • Outlets: Horizontal, Verticle, and Verticle with pressure compensation
