Sharpening of cutting rotors is the key process in terms of the service life of the rotor. The operation time of a cutting rotor between two sharpening procedures, its overall service life, and the quality of the pellets is heavily dependent on precision sharpening. Having more than 70 years’ experience in pelletizing, and handling over 6,100 rotors a year, we are the world’s leading supplier in the rotor sharpening sector. In addition, more than 35 grinding machines at various global locations guarantee short throughput times for our customers. The sharpening serviced we offer guarantees the same optimum tooth profile as on the original rotor. Maintenance costs are significantly reduced, as the longer service life of the rotor and cutting blade minimizes downtimes for adjustments.
