Innovative Gravimetric Screw Feeders

Innovative Screw Feeders

Trantec specialises in the design and manufacture of Gravimetric Feeders for dry bulk solids applications across the globe. Feeders are versatile with the types of product that they are able to process, with varying materials such as harsh granules, flakes, and fine powders being just a few examples.

For those unfamiliar with the term, Metering Feeders have been given many different names over the years, such as:

  • Metering Screw Feeders
  • Auger Feeders
  • Screw Feeders
  • Feeders
  • Volumetric Feeders/Gravimetric Feeders
  • Auger/Agitator Metering Mechanisms

Using the latest technology, coupled with advanced weighing systems, Trantec’s Feeders can be customised to meet specific feeding demands.

With our customisable machined Augers and Load Transducers, feed rates of 1/10g – tonnes per hour can be achieved.

Trantec’s Metering Feeders are in operation worldwide, used for bulk solids applications by universities, global blue-chip firms, multinationals, small businesses, including many major brands. We deliver high accuracy in all areas of bulk handling, serving an assortment of industries, including:

  • Food, Drink, and Confectionery.

Tailored solutions

We understand that one Feeder does not always meet all customer requirements. Trantec overcame this with the introduction of customisable and interchangeable Augers. Modular in design, they are based on core solids metering technology.

Our machines are also available with a Quick Release option and adjustable storage capacities. Both Volumetric and Gravimetric dosing can be applied, including complex Loss in Weight metering.

Product testing and trials

Trantec provides both in-house and external testing of materials as we understand the importance of trialling and demonstrating products. We provide a try-before-you-buy scheme for larger orders (including Augers) which will instil confidence in Trantec’s machines and allow any issues to be dealt with accordingly.
