Extrusion International 1-2020

41 Extrusion International 1/2020 to cleaning procedures is reduced to a minimum thanks to the intelligent machine design. Versatile size reduction system with interchangeable grinding elements With the Ultraplex 1000 UP fine impact mill, HosokawaAlpinewill launcha ver- satile mill for the size reduction of soft materials to 3.5 Mohs’ hardness. De- pendent on the feed material, the fine impactmill canbe equipped simply and quickly with different, interchange- able grinding elements. “Flexibility in production plays an increasingly im- portant role. The interchangeability of the grinding elements is a significant advantage for users”, reasons Bernd Kneisl, Operations Director of the Recy- cling and Granulator Division in Hoso- kawa Alpine’s process technology busi- ness segment. Equipped for any task: The 1000 UP can be employed as a beater mill without sieve but with beater disc, swing beater or plate beater grind- ing unit for operation with grinding tracks or sieve rings. In the plastics industry, this versatile mill can really show its true mettle above all when it comes to the fine grinding of poly- amide, PVC PTFE or PE. Dependent on the grinding element, fineness values in the range of approx. 50 µm to 5 mm are achieved. Just as ex- tensive as the equipment of the fine impact mill are also the available de- signs: dependent on the customer’s individual requirements, the 1000 UP can be delivered with a cast housing made either of mild steel or stainless steel. Universal in use and compact in design Hosokawa Alpine will also estab- lish the Polymer-Line PL-XS 45/100, a compact granulator for the eco- nomic size reduction of large-volume and bulky plastic products. Thanks to its special cutting chamber ge- ometry, the granulator has excellent product intake and size reduction properties. “The ingenious cutting chamber design also ensures quiet machine operation, as the result of which the instances of feed product being ejected from the machine are reduced to almost zero”, says Jörg Krause, Head of Engineering of the Recycling and Granulators Division of Hosokawa Alpine’s process technol- ogy business segment. Low-dust comminution: Another highlight of the Polymer Line is the hydraulic opening mechanism for optimum access to the cutting cham- ber. The cross-scissor-cut rotor devel- oped by Hosokawa Alpine guaran- tees energy-efficient and low-dust comminution. The optional sound insulation reduces the noise emis- sion during operation. Due to their characteristics, the mills of the PL-XS product line can be used both as an- cillary mills and as central mills. The manifold possibilities of adapting the machine to the respective feed prod- uct emphasise the universal applica- tion.
