| 20090110766 | Coupling for Pelleting Mill - A pelleting die assembly includes a tubular die that is rotated by a quill flange. During rotation, particulate material inside the tubular die is extruded through extrusion holes by rollers inside the tubular die. The die is coupled to the quill flange by a flat, annular disc having one side attached to the die by bolts and an opposite side attached to the quill flange by other bolts. The bolts extend axially through the annular disc and face in opposite directions. The annular disc may include grooves to allow cyclic deflection of the die in a radially outward direction while reducing cyclic loading and strain on the quill flange. | 04-30-2009 |
