Introduction of new improved Technologies that convert fibers into recyclables


Brabender Technologie focused on a feeder specially designed to tackle recycling tasks at the Solids trade fair in Dortmund on April 1 and 2, 2020. The manufacturer of bulk material handling equipment therefore specifically utilized the synergies generated by the Recycling-Technik Dortmund show, which took place in parallel. “Solids is an absolute must for us, because this is where the entire bulk materials industry meets up for two days. Here we get the opportunity to compare notes about products and technical innovations with customers, suppliers and other bulk materials experts,” Bruno Dautzenberg, General Manager, highlights.

FiberXpert especially for recycled materials

Carbon and natural fibers that shredding transforms into uneven flakes and fibers. Fibers that snag mechanically on product bridges and don’t reach feed screws.

Brabender Technologie has a reliable solution for feeding problems involving recycled materials: the FX50. This fiber feeder was specially developed for feeding recycled materials like carbon and natural fibers, recycled PP, PET and bottle flakes, shredded plastic or carpet residues and other fiber products like cellulose, acrylic, aramid, PPS, polyamide, polymer or polyester fibers. Long, unevenly cut and non-flow-capable fibers can be fed reliably with the aid of a special fiber screw, hopper design with large inflow cross-section, large, steep-walled hopper and special agitator geometry and positioning.

Potential applications for the FiberXpert include mixing in strengtheners or fillers during the compounding process as well as biopolymers, recycling plastics, fibers in building materials or in the production of films/foils, where offcuts or waste from the startup process are recovered.

Alongside the FX50 Brabender Technologie also showcased a selection of other equipment at the Dortmund trade fair:

  • the recently unveiled DSR28 and DDSR20 twin screw feeders
  • a DSR28 agitator feeder in combination with a FlexWall 40 functioning as a filling unit a FlexWall 40 in a plexiglass finish
  • Materials Area with product samples

Snagged fibers only move in the form of clots, while extremely fine powders behave like fluids when they are in motion and other products become electrostatically charged and adhere to surfaces.
