Definitions

  • the invention relates to a device for adjusting of the crushing gap on jaw crushers with a fixed one and a swinging jaw, the lower one End of the vibrating crushing jaw over a pressure plate system, an abutment and a sliding one Wedge against the crusher housing, and - around that Secure the printing plate system in its position - by means of Springs that are supported against a traverse by on the lower end of the swinging jaw Retractor bars pressed against the pressure plate system becomes.
  • the invention aims at avoiding the known jaw breakers occurring, described Problems and related difficulties.
  • the relief valve allows for a change of the crushing gap the reduction in pressure in the hydraulic cylinders except for a residual pressure.
  • the adjustment takes place in the jaw crusher according to the invention of the crushing gap in such a way that after a Relief of the hydraulic cylinders by the relief valve is made possible and for relaxation the springs lead, the wedge accordingly - to enlarge of the crushing gap upwards, to reduce the crushing gap down - is moved.
  • the hydraulic cylinders do not serve as springs; she change their position during crushing practically not.
  • an automatic Adjustment of the crushing gap enables that for the displacement of the wedge provided a servomotor is.
  • Hydraulic cylinder in connection with a pressure measuring device, when the lower preload pressure is undershot in the hydraulic cylinders during crushing acts on a pressure generator in such a way that the pressure in the hydraulic cylinders again upper preload pressure reached. So that is constant Maintaining sufficient preload on the Pressure plate system guaranteed.
  • the hydraulic cylinders are equipped with a pressure switch, which falls below a minimum pressure in the Hydraulic cylinders triggers a warning signal so that one manual or automatic pressure increase can be effected can. This avoids that with an enlargement of the crushing gap, the spring tension and thus the residual pressure is reduced to below a minimum pressure.
  • the crank swing crusher shown in FIGS. 1 and 2 has a crusher housing 1, a fixed Jaw 2 and a vibrating jaw 3.
  • the Fixed jaw 2 is fixed to the crusher housing 1 connected while the lower end of the swinging Crushing jaw 3 via a pressure plate system 4 Abutment 5 and a slidable wedge 6 against that Crusher housing 1 supports.
  • the swinging jaw is to secure its position 3 by means of springs 7, which are against a traverse 8 support by swinging at the bottom of the Crusher jaw 3 articulated retraction rods 9 on the crusher housing 1 attached.
  • the - in the drawing in Direction of view of Fig. 1 immediately one behind the other - Retraction rods 9 are through the crossmember 8 passed through.
  • On the jaws 2 and 3 facing away The end of each retraction bar 9 is between the Traverse 8 and a washer 10 each have a spring 7 arranged.
  • the spring 7 is preloaded by means of Screws 11 over the washer 10.
  • the wedge 6 is moved by means of a Adjusting motor 12, which is attached to the crusher housing 1 is (Fig. 1).
  • the springs 7 are biased in that initially a rough setting with the screws 11 made and then the hydraulic cylinder 13 with pressure is applied so that the cross member 8, the springs 7th presses against the disc 10.
  • each hydraulic cylinder 13 stands with a pressure measuring device 17 in connection, which on acts on a pressure generator 18. Furthermore, each hydraulic cylinder 13 with a relief valve 19, a Pressure switch 20, and a directional valve 21 provided.
  • the Relief valve 19 the pressure in the hydraulic cylinders 13 lowered to a residual pressure.
  • the maintenance this residual pressure is very important because that Printing plate system 4 a minimum retraction force in the Retraction bars 9 are mandatory so as not to fall out.
