Extrusion International 6-2022

44 Extrusion International 6/2022 K 2022 Solutions for Polymer Processing PEARLO ® X- Series The PEARLO ® X Series Underwater Pelletizer has been specially designed to process spherical pellets at high rates and with low production cost. This most efficient and auto - mated system can be used in the production of raw materi- als, like polyolefins, large capacity compounding and high rate engineering plastics. The PEARLO ® X Series can reach production rates of up to 80.000 kg (176,000 lbs.) an hour. The operational benefits of the PEARLO ® X-Series in- clude liquid-heated die plates with a diameter that more than 2,000 holes can be provided. The die plates include tungsten carbide nibs for resistance against wear and cor- rosion. The cutting tools and the cutting chamber have been revised to optimize the cut, pellet cooling and pellet shaping as well as the thermodynamic conditions. The cut- ting chamber has a unique two-piece geometry allowing good access and easy start up. Water flow into the cutting chamber is optimized throughout a bidirectional orienta- tion ensuring excellent cooling and pellet extraction even on sticky and low viscosity grades or difficult to process modern materials at high rates. This feature provides ho- mogeneous pellet heat history and crystallization as all pellets experience the same residence time in the cutting chamber. The cutter hub is a self-aligning design which al- lows for optimum misalignment compensation. The cutter blades are designed for sequential cutting reducing pellet sticking further and allowing a blade tip speed of 30 m/s. Comprehensive recycling solution MAAG’s expertise in downstream equipment enables the company to meet the rigorous demands of the virgin polymer industry. MAAG Group's downstream equipment recycling sys- tems help users to quickly and efficiently remove heavy contaminants such as paper, aluminum and wood to pro- duce reusable pellets. MAAG equipment is the right choice for mechanical, chemical and advanced recycling. MAAG Downstream Equipment recycling systems are co- ordinated to each other, and can be operated via our pro- prietary control system. Dry Cut Strand Pelletizing for demanding pelletizing applications At this year's K in Düsseldorf, three exhibits from the field of dry cut strand pelletizing will be exhibited at the MAAG booth. The focus is on simplified handling and pro - cess optimization – which should make the production of plastic granules even more sustainable. As a flexible all-rounder for masterbatch and compound - ing applications, a further developed PRIMO S under the name SI, will be on display. The machine comes with a re- vised base frame, which simplifies the integration of down - stream equipment and machine handling. With the open design, the area under the machine is completely visible and accessible from all sides. The cutting head, as a unit with the base plate, drive and sound insulation hood now sits directly on four custom-made vibration dampers. Thus, the entire cutting head including attachments is complete- ly decoupled from the base frame. In addition to the base frame, the acoustic hood has also been revised. As a result, the entire machine looks slimmer and the noise level is fur- ther reduced. The granulator is driven by an intelligent gear motor with integrated frequency converter and mini-PLC. Under the name EBG, MAAG is presenting a strand pel- letizing system for highly filled, hydroscopic and water-sen - sitive compounds. EBG scores with a high degree of auto- mation, gentle material processing and excellent product quality. With a third exhibit, MAAG allowed its customers to im- merse themselves in the virtual world through an AR model of a JSG900 pelletizing system. Die plates for highest quality requirements For the first time, a complete AMN Central Injection Sys - tem (CIS) consisting of a 1500 mm diameter die plate with a central water injection and sword shaped knives will be dis- played at the MAAG Group booth at K-Show. CIS was de- signed to improve pellet cooling and ejection; and is an ef- fective solution for high melt index or peroxided polymers. Centrifugal Drying Innovation The eXsoTM centrifugal dryer now includes additional features that add value and improve performance for dry- ing underwater and wet cut strand pellets. The innovative design of the eXso dryer includes features and enhancements that were developed to increase reli- ability, reduce changeover time and improve product qual- ity. A defining feature is its 3-door housing, which allows greater access and visibility to the interior of the unit. This allows for faster and more effective cleaning and lowers the risk of cross-contamination. In addition, eXso required 23% less floor space compared to centrifugal dryers of sim - ilar capacity.
