Abstract
A gas-flow type chipping machine with a rotating beater-wheel system. In order to chip the feed material, this material is delivered axially into the central area of the beater wheel, where it is deflected and moved in a radial direction to the chipper tools that are arranged in a circle around the beater wheel. In order to ensure that the wear is even along the length of the chipper tools, at least two impact surfaces are arranged so as to be axially staggered to the depth of the chipping space, the impact surface that follows in the axial direction of delivery projecting beyond the axial projection of the preceding impact surface. In addition to the foregoing, the present invention discloses a method for optimizing the size and position of the impact surfaces of a chipping machine according to the present invention.
