Smart Molding International 3-2022

40 peripherals & automation smart_molding international 3/2022 F or industries from chemical and plastics to food and pharma- ceutical as well as recycling and battery compound manufacturing, Coperion and Coperion K-Tron provide a variety of innovative technologies to fit the specific needs of countless ap- plications. At this year's booth, Coperion was presenting the proven WZK two-way diverter valve that has impressed us- ers for over 60 years with its reliability, serviceability, and versatility for use in a wide variety of applications. Further- more, Coperion K-Tron was introducing the new ProRate PLUS line of feeders as well as the high-precision K3-V100 vibratory loss-in-weight feeder and the K3 pharma feeder with the P10 sani- tary vacuum sequencing receiver. In the open area between Halls 4, 4A and 3A, Coperion provided an- other opportunity for attendees to get to know their broad spec- trum of rotary and diverter valves by visiting the Coperion Show Van. They could also experience the ad- vantages in safe and economical bulk material handling equipment Coperion has to offer. 60 Years of WZK Two-Way Diverter Valve: Often Copied, Never Equaled As a highlight at Powtech, Coperion was presenting the proven WZK two- way diverter valve. Thousands of these valves have been used over decades and still to this day, impresses us- ers with its compact and serviceable construction that is suited for a wide variety of applications. It is designed for an operating pressure of up to +5 barg and can be used both for dilute or dense phase conveying lines as well as for gravity pipes. Its aluminum housing with stainless-steel pipe inserts keeps its weight low, making installation easy. To ensure straightforward operation, the diverter valve offers quick access to its internal parts, an advantage not only for maintenance tasks, but also for making cleaning easy. The gentle deflection angle (+/-35°) and more even cross section provide gentle product conveying. Moreover, the WZK is equipped with pressure-as- sisted seals, assuring that the diverter is sealed from one channel to the other as well as to the outside. With its one- of-a-kind construction, the seal adjusts to the conveying pressure with no need for additional utility air. Furthermore, it is suited for use in ATEX zones. New Efficient Solution for Simple Feeding Applications: ProRate PLUS Feeder Line Coperion K-Tron was introducing a representative of the new ProRate PLUS feeder line at the show. This new gravimetric feeder line is a depend- able, high-performance and efficient solution for feeding pellets and other free-flowing bulk materials in plastics applications, offering a good price- performance ratio as well as short lead times. The ProRate PLUS single screw feeders can be installed as individual units or in groupings of up to six feeders around a single process intake, depend- ing upon the recipe. Its unique design enables very compact, space-saving configuration so that up to six feeders can be grouped together within a ra- dius of 1.5 meters around one extruder intake. The three feeder models — PLUS-S, PLUS-M and PLUS L — cover a broad spectrumof feeder performance. Depending upon the material, the Proven, successful technology and a new feeder line: Coperion and Coperion K-Tron at Powtech 2022 At this year’s Powtech (27- 29 September 2022, Nuremberg, Germany), Coperion and Coperion K-Tron were presenting versatile bulk material handling and feeding solutions. The proven WZK two-way diverter valve has been impressing users for over 60 years with its reliability, serviceability and versatility in use (all pictures: Coperion)
