Nordson launched BKG® Particle dryer makes its first user Domo Engineering Plastics GmbH To reduce maintenance time 70% As much as possible, thus improving the production efficiency.
This particle dryer, designed to work with Nordson's BKG® granulation system, incorporates the latest design to significantly reduce the time and costs associated with replacement of 'worn' parts, and responds comfortably to people filling glass fiber and Challenges arising from the increasing use of other abrasive materials. Nordson will introduce this dryer at the NPE2018 show (W2525 booth).
BKG® Particle dryer
This dryer design reduces the number, complexity, and cost of components that are subject to wear, making them easier to service for maintenance or replacement. Although the overall appearance and footprint of the new dryer is similar to that of a standard BKG dryer, The output is also quite good, but the configuration of the wearable components is quite different. The new design simplifies maintenance and requires only one person to perform maintenance tasks, which can reduce production downtime.
Matthias Köhler, Operations Manager, Domo Engineering Plastics GmbH, Prömitz, Germany, stated: 'Our maintenance time has been reduced by up to 70%. Now that we can determine the specific maintenance intervals, we are able to plan in advance and anticipate downtime. Time. 'Domo is the first user of the new particle dryer and installs it on an existing underwater pelletizing line for processing a wide range of polyamide 6 compounds (glass fiber content up to 50%).
Rotor in the pellet dryer
Frank Asmuss, Nordson’s global product manager for BKG granulators, presented a series of design enhancements to reduce wear or simplify maintenance:
● Particle inlet. Frank Asmuss said: 'One of the results of the new design based on the fluid simulation is that the inlet now enters the dryer housing along a tangent line, reducing the impact on all parts of the lower dryer section and allowing quick access to the rest. All wear parts. '
● Rotor. Thanks to the optimized particle inlet, the rotor, especially the lower part, is simplified, and by reducing the influence of abrasive particles, the wear is also reduced to a minimum level. Other measures taken to reduce or eliminate the wear caused by the particle flow include the use of new The cover design and countersinking of the screw head. Frank Asmuss said: 'In the standard dryer, the disassembly and reassembly of the rotor takes 10 hours, and the new design reduces this time to about 3 hours.'
● Particle outlet. The new design reduces the parts that are subject to wear and makes it easier to service. The disassembly/reassembly time has been reduced from 6 hours to 1 to 4 hours.
Frank Asmuss commented: 'These changes we made to the design in order to reduce wear and tear significantly reduce the overall cost per ton of glass fiber filled products. Together with shorter maintenance times, the dryer's overall operating costs are significantly reduced. This is a great advantage for our customers. '
