Bischof + Klein, Europe's leading producer of film and laminates, said that the addition of a newly designed tool holder to its granulator will not only greatly extend blade life, but also significantly improve particle quality. Nordson will be exhibiting at NPE2018. (W2525 booth) introduced the knife holder design.
Bischof-Klein used Nordson's BKG® underwater pelletizer to mix colorants and additives on its blending line for its own film manufacturing operations. When the company installed Nordson on two of its pelletizing lines. New BKG® HiCut TM After the tool holder, the service life of the blade mounted on the tool holder is 2 to 3 times longer than that of the old design, but when using some materials (especially non-abrasive compounds), the blade usage time is extended from the usual three days. For nearly three weeks. In addition, particles produced using this blade exhibit less 'tails' (this type of tailing is separated from the particles as a powder after it has been produced, which may wear out or clog the equipment and cause a waste of polymer. ).

Eduard Beifus, responsible for masterbatch regeneration and enrichment at the Bischof + Klein plant in Lengelrich, Germany, said: 'Because the new Nordson design increased the number of blades on the tool holder by 50%, we were able to reduce the tool's rotation speed. , while maintaining our standard high-level throughput. The reduction in drive speed not only results in less blade wear, but also significantly longer service life.
In the underwater pelletizer, the polymer strands come out of the stencil and solidify as they enter the water and are then cut into granules by blades mounted on the turret. The new HiCut design can be installed on each turret Up to 100% angled inserts and up to 54% right angle inserts. This can increase throughput or reduce granulator speed, reducing wear on the formwork and inserts.
Frank Asmuss, global product manager for BKG granulation systems, said: 'The blades on the BKG HiCut toolholder have round edges and a smooth surface and use countersunk screws. This optimises flow and reduces swirling, and there is more space between the blades As a result, particles do not accumulate. For some products, new designs can increase throughput, making it possible to invest in smaller pelletizers and save costs.
The BKG HiCut design is compatible with all existing granulator systems and the tool holder can be fitted with angled inserts and right-angle inserts.
