Definitions

  • the present invention relates to the field of roll mills, in particular of high-bed roll mills. It relates to an arrangement with a roller and a drive for a roller mill.
  • Roll mills are used for grinding materials, in particular ores, cement or other hard and brittle materials. They are particularly energy efficient compared to other mill types.
  • a roller mill comprises two counter-rotating rollers 1, which are for example mounted horizontally rotatably in a frame.
  • One of the two rollers 1 is displaceable orthogonal to the axial direction of the roller 1.
  • the other of the two rollers 1 is not displaceable in this direction.
  • This displaceable roller 1 is pressed by a spring system on the non-displaceable roller 1. Material is filled from above between the rollers 1, guided by the rotation of the rollers 1 down and crushed by the resulting between the rollers 1 wedge.
  • the rotation of the rollers 1 is usually carried out by separate drive.
  • Fig. 2 shows a roll mill with two indirect drives.
  • Each drive has a motor 91, which is connected by means of a propeller shaft 92 and a planetary gear 93 with the roller.
  • DE 4110643 describes a roller mill in which a roller is driven by a gearless electric motor.
  • a rotor of the electric motor is arranged coaxially around a shaft of the roller and rotatably connected to this shaft.
  • a stator of the electric motor is externally coaxially arranged around the rotor so that a radial air gap between the rotor and the stator is formed.
  • the stator is attached to the corresponding bearings of the rollers. Due to the connection of the stator with the bearing of the roller, no relative movements occur between the rotor and the stator.
  • this has the disadvantage that the stator belongs to the dynamic system, which system is coupled to the spring system, and therefore the weight of the dynamic system is considerably increased. This results in additional dynamic loads, which require further reinforcements of the system.
  • Object of the present invention is to provide an arrangement for a roll mill which allows a reduction in the weight of the dynamic system.
  • the object of the invention is that the arrangement comprises a roller and a drive.
  • the drive comprises a rotor with poles and a stator with stator windings.
  • the rotor is rotatably connected to the roller.
  • the stator is arranged offset to the rotor in the axial direction so that an air gap in the axial direction of the roller results between the stator and the rotor.
  • the stator windings and the poles are arranged in a plane orthogonal to the axial direction of the roller on facing sides of the stator and the rotor.
  • This arrangement of the drive may alternatively be referred to as transversal flux machine. This has the effect that a movement orthogonal to the axial direction of the roller has no influence on the axial air gap between the rotor and stator.
  • a first preferred embodiment relates to an arrangement with a drive, which drive has two axial air gaps.
  • a drive which drive has two axial air gaps.
  • either the rotors or the stator can be laterally bordered by the respective other counterpart in the axial direction. This allows a more compact design and a higher portable box and moment.
  • the two drives can also be arranged on opposite ends of the roller mill.
  • a drive can be provided on both sides of a roller.
  • the poles of the rotor can be formed either by permanent magnets or by electrical excitation. LIST OF REFERENCE NUMBERS 1 roller 2 wave 3 camp 4 rotor 41 rotor frame 42 Pole 5 stator 51 stator 52 stator core 53 stator windings 90 engine 91 propeller shaft 92 planetary gear
