Abstract
The pellet mill includes a ring die having die openings and rollers within a die cavity defined by the ring die whereby material fed to the die cavity and in the nips between the rollers and ring die is extruded through the openings to form pellets. The roller shafts are cooled by a water injector comprised of a tube disposed within and spaced radially from the interior surfaces of a bore through the roller shaft. A fitting at one end of the tube has an inlet for supplying cooling water to the interior of the tube. A return passage for the heated cooling medium is provided in the annular space between the tube and the bore terminating in an outlet in the fitting. In this manner, the roller bearings and lubricant are cooled.
