... was not the only reason for the English Polypipe Group to purchase the Krah Compounder Concept.
Since many years Krah is with the ComTruder® involved in the inline compounding technology.
Until today the system was used to produce and to extrude a compound based on PE/PP with glass-fiber or Calcium Carbonate as a part of the spiral pipe production machines KDR700 and DR700.
For Polypipe now Krah developed a standalone compounder to produce Polyethylene Pellets, filled with Calcium carbonate (30%). The standalone compounder, called Comtruder®, has an output of 700 kg/hr. The pellets are produced by an underwater pelletizer, what is flanged directly to the comtruder.
The energy consumption of the new Comtruder® compared to normal Compounder is 30% less, due the unique Krah-compounding-system.
The new material is used in the existing two KR-production lines at Polypipes plant.
If needed the complete system can be used for Direct Extrusion also.
The Krah Comtruder® is also equipped with
Krah Comtruder® for improving competitiveness by Saving Energy and Optimization the mechanical, physical and chemical properties of raw materials!
