Abstract: A mixing apparatus in which parallel augers are located in a box. The upper mixing augers have specially shaped flighting which provides straight edges linked by corners rather than the conventional helical edge. The lower conveying auger is a helically edged auger with notches at intervals along the edge providing radially oriented surfaces which assist in engaging the material.The flighting of the special straight edged augers is produced from a square blank of sheet metal by pressing it into the spiral configuration required and attaching it to the auger shaft. The complete flighting is made up by several such sections joined end to end.
