Definitions

  • the invention relates primarily to an extrusion mill with a frame, a stationary extrusion roller frame installed within the frame, supporting at least a single extrusion roller with a drum shaped die installed around the extrusion rollers, which is rotated relatively to the extrusion roller frame by means of a driving mechanism.
  • a known extrusion mill concept features an extrusion roller frame which is generally stationary within the extrusion mill frame.
  • the extrusion rollers rotate around generally stationary extrusion roller shafts which are supported by the extrusion roller frame.
  • the extrusion rollers cooperate with a drum shaped die installed around the extrusion rollers.
  • the drum shaped die is rotated by means of a driving mechanism.
  • a gear or pulley is installed at the circumference of the drum shaped die, which engages with a pinion shaft or belts, installed in the extrusion mill frame which is driven by a motor.
  • the die is generally supported by bearings, installed around the generally stationary extrusion roller frame or in the ,partly surrounding, stationary extrusion mill frame. Seals are applied between various relatively to each other, moving parts of the extrusion mill.
  • the invention foresees in an extrusion mill of described type at which these disadvantages in a simple, though effective manner, are eliminated.
  • the extrusion mill according the invention features the characteristic of a driving mechanism which integrates the stationary housing of an electrical motor with the stationary extrusion mill frame and rotary shaft of the electrical motor with the rotary die support.
  • the described construction according the invention leads to a number of important advantages.
  • the electrical motor stator and rotor interact in principle without friction, which obsolete the need of lubrication. Complicated lubricant seals are no longer required. A minimum wear takes place which limit maintenance efforts to an absolute minimum.
  • the extrusion mill according described invention does not suffer from transmission losses because a transmission as applied at known extrusion mill concept is not applied. Because of this, an extrusion mill according the invention can increase performance at identical energy consumption.
  • the stationary extrusion mill frame can be integrated with a stationary motor component.
  • the generally stationary extrusion roller carrier can be integrated with the stationary motor component as well.
  • the extrusion roller frame is considered to be generally stationary relatively to the extrusion mill frame, while the die is rotating around the extrusion roller frame , relatively to the extrusion mill frame.
  • the die it is possible to give the die a stationary position and have the extrusion roller frame (together with the supported extrusion rollers) rotating relatively to the die and extrusion mill support frame.
  • an alternative construction of the extrusion mill is mentioned with a stationary mill frame, a rotary extrusion roller frame which supports at least a single extrusion roller with a stationary drum shape die, surrounding the extrusion roller, were the roller frame rotates relatively to the die by driving means which integrates the stationary and rotary component of an electrical motor and extrusion mill.
  • the die can be executed as stator, yet the possibility exists to execute the extrusion mill frame as stator.
  • typical characteristic of the extrusion mill according the invention is a construction with a limited number, simple components, which makes it possible to keep the manufacturing cost of the extrusion mill according the invention low.
  • the partly drawn extrusion mill in the diagram is equipped with a mill frame 1 and an installed, stationary extrusion roller frame 2.
  • the stationary roller frame is shaped like a tube by means of any known process to allow installation of not displayed lines, required for controlling the extrusion roller 3 at the front end of the roller support frame 2.
  • the extrusion rollers rotate around the roller shafts 4.
  • the extrusion roller frame 2 is surrounded by the drum shaped die 5 at the position of the extrusion roller 3.
  • the drum shaped die extension 6 is supported by support points in the mill frame 1.
  • Bearings 7 are sketched in the diagram between die extension 6 and mill frame 1.
  • bearings 8 are placed between inner circumference die extension 6 and outer circumference extrusion roller frame 2 for a stable die support.
  • An axial bearing 9 and seal 10 are part of the construction.
  • an electrical coil 11 is mounted which makes the die extension 6 function as the rotor in an electrical motor.
  • electrical coil 12 is installed at the inner side of the mill frame 1, which makes the mill frame function as the stator in an electrical motor.
  • the combination of mill frame 1 and die extension 6 with die 5 forms in principle an electrical motor at which die extension 6 with die 5 functions as the electrical motor shaft. In this fashion, die 5 can be directly driven in a simple way.
