Segmented knife assembly with replaceable wear segments

A segmented knife assembly for a mixer apparatus, the segmented knife assembly having a front, a rear, and a perimeter with a cutting edge forming a portion of the perimeter of the knife assembly, the segmented knife assembly comprising:

• a support segment positioned toward the rear of the knife assembly for positioning on the auger of the mixer apparatus when the knife assembly is mounted on the mixer apparatus;
• a positioning segment on the support portion and defining a pair of positioning pockets, the positioning pockets being oriented toward the cutting edge of the knife assembly;
• and
• a pair of cutting edge-forming segments each being removably positioned in one of the positioning pockets, each of the cutting edge-defining segments including a cutting edge section to collectively form a portion of the same cutting edge of the knife assembly;
• wherein the positioning pockets and the cutting edge-forming segments are configured such that the cutting edge-forming segments are interchangeable between positions along the same cutting edge.

• a support portion positioned toward the rear of the knife assembly for positioning on the auger of the mixer apparatus when the knife assembly is mounted on the mixer apparatus;
• a positioning portion on the support portion and defining at least two positioning pockets, the positioning pockets being oriented toward the cutting edge of the knife assembly;
• and
• a cutting portion forming the cutting edge of the knife assembly, the cutting portion including at least two cutting edge-forming segments removably positioned in the pockets of the positioning portion such that the cutting edge-forming segments form adjacent portions of the cutting edge;
• wherein at least one aperture formed in each of the cutting edge-forming segments is alignable with a hole in the support portion to permit a fastener to removably mount the segment to the support portion.
