Definitions

  • the invention relates to the field of fragmentation machines, also called machines for grinding and / or crushing material, such as ores. More precisely, the invention relates to the field of grinding machines in which the material is crushed between a cone and a frustoconical bottomless tank by setting the tank in motion relative to the cone.
  • the machine comprises a conical head, also called the cone, housed in a tank, a space being defined between the head and the tank.
  • the conical head is in a fixed position relative to a frame, while the tank is positioned on a supporting structure, mounted floating relative to the frame.
  • the supporting structure is movable in a horizontal plane relative to the frame by means of vibrators which are set in motion by appropriate means.
  • the conical head is mounted to rotate freely around a vertical axis relative to the frame, in order to limit the wear phenomena due to movements in a tangential plane between the tank and the head.
  • the height of the cone relative to the tank can be adjusted, so as to adjust the minimum width of the space between the head and the tank, and therefore the maximum size of the ground products.
  • the thickness of the layer of material is deduced therefrom, and therefore the maximum size of the crushed products. By comparing this thickness with a target value, it is possible to adjust the machine parameters.
  • the document EP 0 833 692 describes a system for setting the tank in vibration making it possible to limit vertical vibrations.
  • several vertical vibrator shafts are mounted on a frame supporting the tank, each shaft carrying a vibrator composed of two weights arranged on either side of a base of the frame defining a horizontal plane.
  • the vibrators when the vibrators are rotated, the forces they exert are located in the horizontal plane of the base.
  • the vibration setting system comprises vibrator shafts, generally four, arranged in a square around the tank and the conical head.
  • a first vibrator shaft is coupled to a motor, and the other shafts are driven from the first shaft by a set of pulleys and a belt.
  • the rotation of the vibrators must be synchronized to avoid the appearance of parasitic moments.
  • the vibrator shafts When starting the machine, the vibrator shafts are rotated, their speed gradually increasing to a nominal speed. The material poured between the head and the tank is then crushed. However, without any particular precaution, the vibrations of the tank pass through different frequencies, some of which may correspond to resonant frequencies of the machine, which is detrimental for the machine.
  • phase shifting device to adjust the angular offset of a group of vibrators relative to the other group, in order to modify the amplitude of the resultant of the forces generated by the vibrators.
  • two vibrators are in phase opposition with respect to the two other vibrators so that the resultant of the forces generated by the vibrators is zero: the tank is stationary with respect to the head. Phase opposition is maintained until rated speed is reached. Then, all the vibrators are put in phase, so that the resultant of the forces is maximum, and the tank is set in motion with respect to the head to grind the material.
  • the amplitude can be changed by means of one or two rotary jacks allowing to modify the phase shift of the vibrators of one group compared to those of the other group.
  • the phase shift and the phasing of the vibrators with respect to each other are based in particular on the transmission by the assembly of pulleys and belts, making the adjustment imprecise and unreliable.
  • the wear of pulleys and belts as well as the tension in the belts must be monitored in order to maintain fine adjustment.
  • the belt can also "jump" on the notches of the pulleys, especially as the notches are subject to wear, shifting the angular position of the vibrators relative to each other.
  • the set of pulleys and belts increases the number of parts on the machine, making it more complex, and making maintenance difficult.
  • the hydraulic cylinders for rotating the shafts of the vibrators require a robust seal, both with respect to the pivoting of the shafts, but also with respect to the vibrations of the machine. Many leakage problems can arise.
  • the machine further comprises a device for vibrating the tank relative to the frame in a transverse plane, so that material is ground between the inner track and the outer grinding track by the relative movement of the tank with respect to to the cone.
  • the vibrations to grind the material can thus be adapted online, without stopping the machine, according to the grinding power required to grind the material.
  • the machine thus operates continuously.

  • Each vibrator 8a, 8b, 8c, 8d can be formed of two parts called weights distributed on either side of a substantially transverse plane of the frame 4, so that the vibrations of the tank 3 caused by the rotation of the vibrators 8a, 8b 8c, 8d remain substantially in this transverse plane.
  • Each vibrator 8a, 8b, 8c, 8d is fixed on a shaft 9a, 9b, 9c, 9d with a longitudinal axis vibrator driven in rotation with respect to the frame 4 by a motor 10, including the motors 10 of the shafts 9a, 9b to vibrator are visible on the figure 2 .

As will be explained later, each motor 10 is preferably a reversible motor, that is to say it comprises a motor mode, in which it consumes energy to set the corresponding vibrator in rotation, and a generator mode in which it generates energy by braking the corresponding vibrator.
  • the vibration device 7 can take a multitude of intermediate positions, so as to adjust the amplitude of the vibrations as a function of the required grinding power.
  • the phase shift of the vibrators is carried out two by two.
  • the diagonally opposed vibrators 8a, 8c are in phase with each other, just as the diagonally opposed vibrators 8b, 8d are in phase with each other, while the vibrators 8a, 8c are in phase opposition with respect to vibrators 8b, 8d, that is to say that the phase angle is substantially 180 °.

  • the device 7 for setting vibrations is previously placed in the zero position.
  • An initial grinding power can be determined by the computer 13 as a function of at least one grinding parameter.
  • the initial grinding power determines an initial speed of rotation and an initial phase shift of the vibrators 8a, 8b, 8c, 8d, this initial phase shift possibly corresponding to the maximum position and then to an intermediate position.
  • the control system 11 then gradually increases the speed of rotation of the vibrators 8a, 8b, 8c, 8d until it reaches the initial value.
  • the device 7 for setting vibrations being in the zero position, the tank 3 has little or no transverse displacements with respect to the cone 5. Thus, during the rise in rotational speed, one avoids passing through frequencies of resonance of machine 1 which could degrade it.

  • the grinding power is directly related to the amplitude of the vibrations of the tank 3, which is determined by the phase shift between the vibrators. More precisely, it is the grinding force which depends directly on the phase shift of the vibrators.
  • the required grinding power can be determined in particular as a function of the characteristics of the incoming material and the characteristics targeted for the outgoing material. For example, the greater the size difference between The larger the granules of the outgoing material and the incoming material, the greater the grinding power should be.
  • An example of application relates to mineral processing, that is to say the grinding of ores.
  • the outgoing material has a proportion of granules smaller than a required size, referred to as fines, which is too high. Indeed, fine particles can be detrimental to downstream treatment processes. Thanks to the new machine 1 presented here, the grinding power is adjusted to avoid the production of fines.

By comparing the spectrum of the longitudinal vibrations measured by the sensor with a reference spectrum, it is possible to detect a modification of a parameter. of grinding. A difference between the measured spectrum and the reference spectrum is quantified. It can be, for example, a difference in amplitude, frequency or even a time shift. If the quantified difference exceeds a threshold value, the detection of a modification of a grinding parameter can be confirmed, for example by sending a signal to the device 7 for vibrating, in order to regulate the phase shift of the vibrators.
