Definitions

  • the invention relates to a roller mill according to the preamble of claim 1.
  • the shafts of the grinding rollers are supported by means of radial bearings in arms which can be pivoted about horizontal axes within the mill housing, so that the grinding rollers can be moved vertically with respect to the grinding table.
  • the invention is therefore based on the object of designing a roller mill in accordance with the preamble of claim 1 in such a way that a particularly simple and largely standardized design is achieved which can be equipped with a different number of grinding rollers.
  • the shafts of the grinding rollers are each mounted in two self-aligning roller bearings, one of which forms a fulcrum as a fixed bearing, while the other bearing is designed as a vertically movable floating bearing.
  • the bearings therefore have a double function:
  • the two bearings of the individual grinding roller shafts are expediently arranged outside the mill housing, which enables further standardization of the mill housing (regardless of the number of grinding rollers required).
  • the roller mill illustrated in FIGS. 1 to 4 contains a mill housing 1 with a vertical axis 2.
  • a grinding table 3 is rotatably mounted about the housing axis 2 and contains a circular grinding path 3a on which grinding rollers 4 roll.
  • the grinding rollers 4 are rotatable about their axis 5 and are seated on a grinding roller shaft 6, which is supported in two bearings 7, 8.
  • the two bearings 7, 8 are designed as self-aligning roller bearings, so that the grinding roller shaft 6 can perform a tilting movement in addition to the pure rotary movement in these bearings 7, 8.
  • the bearing 7 is designed as a fixed bearing. Its center 9 thus represents a fulcrum for the grinding roller shaft 6.
  • the bearing 8 on the other hand, is moving vertically Lich floating bearing trained. For this purpose it is arranged in a bearing block 10 which is vertically movable in a sliding frame 11.
  • the shape of the slide frame 11 can be seen in particular from FIG. 3: the lower part 11a of the slide frame 11 is cranked outwards, carries the housing of the fixed bearing 7 and is provided with two eyes 11b, via which the slide frame 11 is pivotably mounted on an axis 12 is arranged lower than the fixed bearing 7.
  • the two bearings 7, 8 are arranged outside the mill housing 1.
  • Hydropneumatic springs 13 are arranged between the bearing block 10, which carries the floating bearing 8, and the upper cross member 11c of the slide frame 11, which press the bearing block 10 in the slide frame 11 downwards.
  • the individual grinding rollers 6 are each driven by a motor 14 via a slip-on gear 15, a torsion torque arm 16 being provided to absorb the torque.
  • the grinding table 3 is provided with an additional auxiliary drive 17.
  • the assembly consisting of the grinding roller 4, the grinding roller shaft 6, the bearings 7, 8, the bearing block 10, the sliding frame 11, the hydropneumatic springs 13, a memory 18 for the springs 13, the drive motor 14 and the slip-on gear 15 is as a whole the axis 12 from the mill housing 1 ago swing out.
  • a hydraulic lifting device 19 engages at the lower end of the bearing block 10, by means of which the above-mentioned grinding roller assembly is pivoted about the axis 12.
  • Fig. 1 the left grinding roller assembly is illustrated in the position pivoted outwards.
  • the hydraulic lifting device 19 can also be used to adjust the floating bearing 8 in the vertical direction by forming a stop which limits the tilting movement of the grinding rollers 4 in the direction of the grinding table 3. Due to the design of the bearings 7 and 8 as a self-aligning roller bearing, the grinding roller shaft and thus also the grinding roller 4 can perform a tilting movement in the vertical direction (around the pivot point formed by the center 9 of the fixed bearing 7) in addition to its pure rotary movement, the hydropneumatic springs 13 generate the elastic restoring forces.
  • FIGS. 1 to 4 illustrate how the roller mill according to FIGS. 1 to 4 can be equipped with a different number of grinding rollers (two, three or four) while maintaining the standard construction of the housing and the individual grinding roller assemblies can be.
  • the individual grinding roller shafts 6 are driven by a fixedly arranged motor 20 and a gear 21 via an articulated shaft 21. If the grinding roller assembly is to be pivoted outwards about the axis 12 in the manner already explained, first the PTO shaft 22 removed which the gear be 21 connects to the grinding roller shaft 6.
  • the grinding rollers 4 are loosely rotatable in the bearings 7, 8 with their grinding roller shafts 6, i. H. not driven.
  • the grinding table 3 is provided with a drive device 23 (with gear).
