Shredder solutions

Herbold Meckesheim, Hall 9– Booth B34

For use in plastic recycling plants, the demand for powerful shredders has grown. Especially those that can process entire bales at the beginning of the reprocessing chain. Modern washing plants in particular, such as produced by Herbold Meckesheim, require sophisticated shredder technology to be able to process high throughputs and challenging feed materials. At the same time, the machines should be largely wear-resistant and as simple as possible to operate and maintain.

An example of a modern solution in recycling lines is the single-shaft shredder 60/210 from Herbold Meckesheim, which handles high throughputs and entire bales of plastic and is suitable for both dry and wet size reduction. It is claimed to combine a robust and durable construction with a maintenance-friendly design thanks to good accessibility through a large double-wing door and a hydraulically swing-away grinding chamber trough. In many washing plants, the EWS 60/210 serves as the first process stage. A special feature of the single-shaft shredder is the externally mounted and wear-protected rotor, which allows individual knife configurations in the cassettes and is equipped with screwed-on armour plates, making time-consuming hard facing obsolete. In addition, the rotor consists of  also replaceable stator knives, and a second row can be fitted as an option. Thanks to its large flywheel masses, the double-sided belt drive is energy-efficient and requires little maintenance without a failure-prone gearbox. An overload clutch is used to protect against extraneous matters, which might cause damage to the machine.

Another example is the double-shaft shredder DWS 45/160 by Herbold Meckesheim. Due to a large contact surface of the rotor, the machine has a salient ingestion performance and is appropriate for materials that could only be fed in batches with traditional shredders, such as big-bags or large voluminous containers. The shredding of the material, whether in dry or wet operation, to a uniform and constant granular size is determined by the selection of the screen.
