Powtech 2017: Brabender Technologie revolutionizes fiber feeding

Manufacturing carbon fiber panels can generate a great deal of waste which then requires disposal. The new FiberXpert from Brabender Technologie helps to solve this problem as it can feed a large range of long fibers. “This allows cost-effective, environmentally sound recycling”, Bruno Dautzenberg, General Manager of Brabender Technologie, explains.

Problem with product bridging

Waste of  40 percent waste causes considerable financial loss. Shredding these panels produces flakes and fibers that when mixed together make feeding extremely difficult. Most natural fibers have similar flow characteristics and difficulty feeding when used as a renewable raw material to reinforce plastics. Similar to carbon fibers, natural fibers mechanically interlock often resulting in the formation of product bridges and starving of the feed screw. “These products do not flow of their own accord but have to be moved”, Jochen Keesen, Head of Brabender Technologie’s Technical Center, explains. “Traditional stirring agitators or vibration cannot work with these materials.”The same applies to PP and PET flakes or other shredded materials like bottle flakes (shredded PET bottles). Here the intermediate recycling step of re-pelletizing can be eliminated if the flakes can be fed directly into the manufacturing process. Another application is the feeding of shredded film from plastic film production edge trim waste. This feeding results in a 10-30 % productivity gain, which until now has been difficult to process. “Many feeding test inquiries prove that FiberXpert is filling this gap”, Bruno Dautzenberg states. 

New Technical Center is ready for action

A testing line is available for FiberXpert in the new Technical Center including the important issue of filling the feeder. “In particular bulk material filling is a critical factor for this piece of equipment. We are able to simulate the whole process in our new Technical Center”, General Manager Horst Vohwinkel explains. FiberXpert can be used with a wide range of very different materials, as it has many optional features. To enable us to select the right components, it is necessary to conduct feeding tests. “Now we have the possibility of working simultaneously with four complete lines, including refill“, Horst Vohwinkel relates. “That enables us and our customers to put suitable feeding processes in place even for bulk materials that are more challenging to handle.” Brabender Technologie is showcasing the FiberXpert fiber feeder and other bulk material feeding solutions at Powtech in Nuremberg from September 26 to 28 in Hall 4 / 237.
