The arcuate segments are laid in an end-to-end fashion to form an annulus with the outside diameter of the annulus having a radial extent greater than the radial extent of the annular carrier. A support shoulder extends axially outward from the annular carrier to contact the surface of the arcuate segments defined by the inside diameter of the annulus. The arcuate segments may be removed and sharpened, whereafter shims are inserted between the arcuate segments and the annular carrier to properly space the segments from an adjacent shearing wheel. Optionally, arcuate segments may be mounted to both side faces of the annular carrier. | |
