Hellweg Maschinenbau Proves Granulator Performance at Fakuma
Hellweg Maschinenbau demonstrated its granulators at Fakuma by successfully size-reducing difficult polymers and rubber compounds. The true scissor-cut technology delivered homogeneous, high-quality regrind.
Roetgen/Germany, October 2026. At Fakuma 2026, Mark Hellweg, Managing Director of Hellweg Maschinenbau, had made an unusual offer to visitors at short notice: “From numerous trials in our technical centre and our experience with our customers’ materials, we know that our granulators can handle (almost) any challenge,” he said. “Anyone who would like to see this for themselves is invited to bring samples of their ‘problematic’ material to our stand to test them.”
The positive response, despite the very short lead time, highlights the importance of the topic. The result is indeed impressive. “By the end of the trade fair, the score was 8–0 in favour of our mills!” Hellweg summarises. Eight visitors to the stand had brought material that they considered difficult to granulate and were eager to see how it would fare in the milling process. On eight occasions, the material disappeared into the hopper of the fully operational MDSi 230/150 mill within seconds. Immediately afterwards, it collected in a tray, each time forming uniformly granulates with a particle size of 2 mm. This even worked with particularly elastic TPE. The team received a soft NBR rubber compound only after the trade fair had closed. This could also be shredded without any problems – no pre-treatment, no addition of release agents, no additional, energy-intensive cooling. Score: 9–0!
Hellweg knows why: “The key lies in our consistent use of genuine shear cutting to treat the feed material. All interested parties were able to take home an ideal, homogeneous ground material with a narrow particle size distribution, a minimal proportion of fine particles and a uniform, smooth-edged geometry, regardless of whether it was TPE, EPS, rubber, nylon or even foam. Our shear-cut granulators handled all tasks with ease.” For Hellweg, it goes without saying that such trials can also be offered at any time in Roetgen.
Prospects look brightening
Following a slow start to the current financial year – typical for this industry – Mark Hellweg is sensing an upturn following Fakuma. His takeaway from the trade fair: “After investment decisions were put on hold for months, companies are starting to invest again. We are seeing rising demand for energy-efficient granulators and smart monitoring systems that help reduce downtime and operating costs. And our order intake gives us reason to hope that, despite the weak start, we will at least be able to maintain 2025’s turnover.” For 2027, he anticipates that the combination of deferred investments and growing demand could support a recovery.
