Abstract
In a mixing device adapted to mix materials flowing therethrough from an inlet end to an outlet end in which there are provided agitating elements as on a rotating shaft, there is provided an internal recycling means to impel a portion of the material, flowing from the inlet end toward the outlet end, countercurrently to the main flow, i.e., toward the inlet end to effect an in situ recycle. There is disclosed a pelleting apparatus having a horizontally-disposed substantially cylindrical shell, a rotating, pin-equipped shaft, inlet and outlet means for feeding material to be pelleted and pelleting liquid into and through the device, the shaft having mounted thereon, at least over a length thereof, at least one reverse-flight or blade adapted to cause motion toward the inlet end of the device of a portion of the mass being pelleted.
