Definitions

  • the present invention relates to roller mills and is particularly concerned with drive means for vertically disposed roller mills. More particularly, the invention relates to drive means for roller mills having a vertical axis, of the type known as resilient rollers and/or resilient force mills. These mills are equipped with a grinding container or vessel or a grinding bed,
  • rollers that roll on this bed which rotate about a stationary axis and are spring biased.
  • the grinding rollers thus are pressedagainst the grinding vessel and the material to be processed is crushed and ground between them.
  • the grinding vessel or bed is driven in a conventional manner by an electromotor with an intermediate special trans mission and rotated, and the rollers that are pressed downwardly from the top are carried along by friction.
  • shocks which are transferred to the special transmission.
  • shocks express themselves on the one hand in axial thrusts against the transmission, while on the other hand torsional or rotary oscillations develop, i.e. loads on the transmission in tangential direction whereby the gears of the transmission are subjected to excessive wear.
  • the invention is based on the problem of eliminating this danger point of the aforementioned mills and to find ways and means how to adapt the drive to the severe operating conditions and to improve the construction.
  • this object is obtained with a drive for roller mills having a vertical axis, in that an area of the outer periphery of the grinding vessel is constructed in the form of the rotor of an electromotor which is surrounded by a stator fixedly mounted in horizontal position in the housing.
  • this form of construction permits an advantageous journalling of the grinding vessel to absorb the axial forces that arise.
  • torsional oscillations and the forces connected therewith can no longer be transferred in tangential direction onto components of the transmission and also axial forces become ineffective with respect to the drive.
  • the drawing shows the lower part of a grinding mill having a vertical axis with the grinding bed and its drive represented in axial section.
  • a grinding bed or grinding vessel 2 is horizontally disposed in the housing 1 of a mill. This grinding vessel 2 is set in motion about the vertical central axis by a drive means. 0n the grinding vessel 2 several grinding rollers 3 roll about their staiffy axles 4, while these axles are under pressure from the of an electromotor. In the embodiment illustrated, the grind ing bed 2 is mounted upon a grinding vessel support 6 having a circular periphery which carries the rotor winding 8 in its lower periphery area 7.
  • the stator winding 9 of this motor is rigidly disposed in housing 1 and surrounds rotor 8 in a horizontally extending area.
  • the grinding vessel support 6 in its turn is journalled in a radial bearing 12 that is mounted in a pedestal 13 of the machine with a plate 10 and an axle stud l1 interposed. Furthermore an axial bearing 14 is disposed between plate 10 and machine pedestal 13.
  • the bearings 12 and 14 may be constructed in any desired and known manner to meet the requirements of the heavy loads.
  • Rotor mill drive in accordance with claim 1 including a base below said rotor having a stud extending downwardly therefrom into said base, an axial bearing between said base and said pedestal, and a radial bearing disposed intermediate said stud and said pedestal.
