Abstract
A mixer for mixing and processing materials comprises a mixing chamber with a mixing space therein, an elongated rotatable mixing shaft extending through the mixing space, and a drive apparatus for rotating the shaft. At least one mixing element is coupled to the elongated shaft for being rotated to mix material. A chopper assembly comprises a chopper shaft and at least one chopper blade coupled to the shaft to be rotated thereby for chopping material being mixed in the mixing space. The chopper blade comprises an elongated blade body with at least one cutting edge, and an edge plate is formed of a wear resistant material and mounted to the cutting edge of the chopper blade to overlie the cutting edge, the edge plate being wider than the cutting edge to prevent premature wear of the cutting edge.
