QR class | Shredder for inhouse plastic recycling

Trouble-free shredding of recyclable materials with the QR class

The QR-class is a new generation of extremely reliable and versatile high-performance single-shaft shredders. These products are all about the trouble-free shredding of recyclable materials. With the QR class, operators can be sure of avoiding unscheduled downtime as these machines do what they were built for - the reliable shredding of material.

The QR class was developed and realised over a two-year period, in cooperation with users from industry and commerce.
This cooperation has resulted in a new series of single-shaft shredders that leave nothing to be desired. In addition to the
robust, universal cutting unit, indestructible body and reliable, completely maintenance-free pusher technology, the technical
highlights of this product also include a resilient drive system that comes with a safety coupling. In contrast to standard
units, the QR class does not require a shaft stub, as the gears are integrated in the rotor. This results in a significant
reduction of repair efforts. Yet another outstanding technological feature is the multi-functional flap that allows quick and
easy access to the cutting chamber for the efficient emptying of the hopper and removal of foreign objects.

Furthermore, the pusher may be cleaned in an ergonomic and safe position. The simple operation is based on a high-resolution
touch-screen display, intelligent pusher controls, long maintenance intervals and the quick and safe access to all
machine components. All these factors combined make operation and maintenance of these units as easy as never before!

And with our 2-year full warranty*, you have complete peace of mind when it comes to ensuring the smooth operation of your unit.

Single-shaft shredding system

Single-shaft shredding systems can be almost universally used and are able to process a broad range of different materials. Depending on the model, they are equipped with a ram system that pushes the material against the rotor with the replaceable cutting inserts. An easily replaced perforated screen defines the desired granulate size.
