Crown cutters, Concave shredders - areas of application

Cutting crowns are also referred to as shredder crown blades, concave cutters, crown style blade, to name a few. These blades are used in particular for shredding plastics, wood and other waste with slow-running single-shaft shredders. Crown cutters with a pronounced groove achieve the most aggressive cut possible on the material; slanted grooves with a high thread increase the stability and thus the service life of the cutting crown.

Case-hardened cutting crowns offer very high breakage resistance and are optimally suit-ed for shredding material rich in impurities. Through-hardened cutting crowns ena-ble a long service life and first-class performance in the shredder, but their use is limited to low-solids material.

Do you have questions about our crown cutters?

Our extensive range of cutting crowns contains numerous variants, including those with counterbores on both sides, oblong counterbores on one side, through-hole threads, M12-threads, or other counterbores, to name just a few examples.

If you have not found the right cutting crown for your shredder, please contact us. We will be happy to help you find replacement parts for the materials you run with your machine.
