Hellweg is showcasing updates to its grinding equipment at prs Europe.  

Its established wet grinder, traditionally used for film recycling, achieves high quality particle size distribution and geometry for non-wovens, textiles and pulp materials.

A new advanced closure and operating concept enables the machine to be closed and locked hydraulically, saving time during maintenance.

All Hellweg grinders can be fitted with a smart control system which monitors power consumption, motor speed and bearing temperatures. The smart control system can optimise motor load and throughput.  The service life of blades, screens and V-belts are also recorded.

One of the newest developments is a smart sonic add-on module. The module uses built-in ultrasound to measure the material flow into the feed system, to ensure consistency. Energy consumption is lowered while the quality of the ground product improves.

The smart flow module, a throughput measurement system that uses microwave technology, is a maintenance-free sensor that measures the flow of bulk material.

The smart control system determines the machine’s current output in mass ground per hour and grinding output, providing data that can be used to plan maintenance work, and avoid unplanned downtime.

Hellweg’s grinders can shred all types of plastic as well as textiles, cosmetics and food products. The grinders can reduce dust and fine particle content by up to 90%, claims Hellweg. The grinding process uses up to 75% less electricity than conventional mills.

Managing Director, Mark Hellweg says: “Stringent recycling requirements and the tight supply of virgin plastic make the availability of regrind a crucial factor for the recycling cycle. The quality of the regrind is a key determinant of the cost-effectiveness of its use. Hellweg’s mills have traditionally set the standard in terms of productivity, energy efficiency, low dust emissions and the ideal geometry of the regrind for further processing. At prs Europe, we will be demonstrating how the use of state-of-the-art grinding technology can help recyclers capitalise on the current circumstances.”
