  • the heat transfer medium is fed from there to the end openings of the grooves of the outer body 38, which is outermost in the axial direction of the rotary body 01, and is introduced into the grooves, after which the heat transfer medium moves the grooves in the direction of the end face 39 of the rotary body 01, at which the heat transfer medium in was passed through the rotating body 01, flows through.
  • the heat transfer medium emerging at the front openings of the grooves of the last outer body 38 in the axial direction of the rotary body 01 can be fed to a channel for the collective removal of the heat transfer medium from the rotary body 01.
  • the grooves, in particular the grooves flowed through by the heat transfer medium can, for. B. have a rectangular cross section (Fig. 12) or a round or semicircular cross section (Fig. 11).
  • the outer body 38 is preferably made of a plastic such. B. manufactured in an injection molding process, for. B. made of a polyamide, and is able to thermally insulate the heat transfer medium flowing through the flow channels 37 preferably against the base body 28.
  • the outer body 38 on the base body 28 is preferably by a material connection, z. B. fixed by an adhesive and attached.
  • the preferably thin-walled cover 36 is, for. B. positively pushed onto the outer body 38 and preferably cohesively on the outer bodies 38 or on the base body 28 or on both. B. attached by welding or gluing.
  • the cover 36 is preferably made of a corrosion-resistant and wear-resistant metallic material.
  • the particular advantage of the rotary body 01 embodied in a layer structure is that no flow channels 37 need to be introduced into the base body 28, as a result of which a complex processing step in the manufacture of the rotary body 01 is eliminated.
  • Some rotating bodies 01 require an arrangement of twenty and more flow channels 37 for effective temperature control of the lateral surface 07 of their bale 02 along the circumference, which in turn z. B. by means of a deep hole with a diameter of z. B. 20 mm to 25 mm in the bale 02 or the base body 28 are introduced.
  • a production of the rotary body 01 is complex and therefore expensive.
