Abstract

The cutter has a rotor with axially parallel vanes and a cutting ring with blade packets dividing the circumference. Each blade packet has a support block to support the blade with it's cutting edge axially parallel and toward the rotor. The wearing surfaces (10.1) of the support blocks (10) are smooth and, with the radius, form an angle which is less than 90 degrees in the direction in which the rotor (1) runs off. The wearing surface is formed on a wearing plate (10.2) fixed to the support block. The wearing surface is produced by welding re-surfacing and then grinding to a smooth surface. The wearing surface is produced by vaporising or coating, especially to produce a ceramic or chromium coating.
