The correct dosing of products that are not optimally free-flowing such as regrind, agglomerate, film flakes or fibers on single and twin screw extruders requires precise technology.
Extruder Feeding Systems
The challenge
Feeding of recycling materials with low bulk density
Loosening of plastic regrinds that are difficult to flow and form bridges, such as film flakes and fibers
Pre-compaction of the material and feeding into the extruder screw at constant pressure
The goal
Extruder feeding systems enable a safe, constant and efficient material supply to the extruder, even with poorly flowing recycled materials or powders.
Reliable material supply to the extruder
Avoidance of process fluctuations in the material feed
Dust reduction
Our process
Continuous feeding and pre-compaction of the product on the extruder by extruder feeding systems for regrind and powder.
Advantages for you
Efficient material supply even for critical, difficult-to-flow products
Individual material-specific design of the feeding systems with regard to bulk density, flow and compression behaviour
Integration into the extruder control system
Useful options such as hydraulic lifting devices or coatings
