Definitions

  • the main shaft of a typical cone crusher is bearing-mounted below the crushing cone only.
  • the main shaft of the crusher is further supported at its upper end to the frame by means of an upper thrust bearing. It is this subtype of a cone crusher that is normally called a gyratory crusher.
  • the gyratory crusher can normally be adjusted by means of a hydraulic system in such a way that the main shaft can be moved in the vertical direction with respect to the frame of the crusher. This makes it possible to change the setting of the crusher in such a way that the grain size of the crushed material corresponds to the grain size desired at each time, and/or to keep the setting constant as the crushing blades are worn.
  • the adjustment may also be made by lifting and lowering the upper frame of the crusher and the crushing blade mounted on it, in relation to the lower frame of the crusher and the main shaft which is stationary with respect to the lower frame in the vertical direction.
  • the power input in the actuator and/or the crushing force is determined continuously, and the cycle frequency of the crushing means is controlled continuously.
  • the arrangement of adjusting the frequency is substantially not dependent of the stroke of the crusher.
  • the adjusting arrangement according to the invention can be applied in various crushers, such as, for example, crushers with long and short strokes.
  • Fig. 3 shows graphs illustrating how the crushing force depends on the cycle frequency of the crushing cone
  • Fig. 4 shows graphs illustrating how the production of the crusher depends on the cycle frequency of the crushing cone
  • a cone crusher unit 1 shown in Fig. 1 comprises a vertical eccentric shaft 2 and an oblique inner hole fitted therein.
  • a main shaft 3 is fitted in the hole inside the eccentric shaft 2, and a supporting cone 4 is often mounted on the main shaft 3.
  • a means called an inner crushing blade 5 and used as a wearing part has been mounted to the supporting cone 4.
  • the supporting cone 4 is surrounded by the frame 6 of the crusher, on which has, in turn, been mounted a means called an outer crushing blade 7 and functioning as a wearing part.
  • the inner and outer crushing blades 5, 7 together form a crushing chamber 8, in which the feed material is crushed.
  • the power input in the actuator 10 and/or the crushing force are determined continuously, and the rotation speed of the actuator 10 and thereby also the cycle frequency of the crushing cone 4 and the inner crushing blades 5 is controlled continuously.
  • continuous determination and continuous control refers advantageously to determination and control several times a second.
  • the power input in the actuator 10 and/or the crushing force are determined continuously as a chain of events repeated at regular intervals, wherein the interval between the moments of single determinations may be 1 to 10 seconds.
  • the rotation speed of the actuator 10 is continuously controlled in a chain of events repeated at regular intervals, wherein the intervals between the moments of single controls may be 1 to 10 seconds.
  • the aim is to find the lowest possible cycle frequency of the crushing cone 4 with the power input of the crusher, because in this way, a high production of crushed material is typically achieved.
  • the highest available power of the actuator is determined, and the cycle frequency is adjusted in such a way that the crushing force and/or the power of the actuator 10 correspond substantially to said highest available crushing force and/or power.
  • the solution of adjusting the frequency of the crushing cone 4 can also be combined with other control arrangements, such as the adjustment of the settings.
  • changing the settings of the crushing blades will affect the power input in the actuator and/or the crushing force of the crushing unit 1.
  • the cycle frequency of the crushing cone is changed, if necessary, to correspond to the changed settings when the settings are changed.
