Definitions

  • the invention relates to a hard comminution process, in particular for ore, lime and rock crushing plants, in which novel comminution techniques are introduced and accomplished with various devices.
  • Single-swing or double-swing jaw crushers, double toggle-jaw crushers, impact crushers and hammer crushers are known as hard crushers.
  • Design types are the cone crusher, impact crusher and
  • the invention aims in particular for hard comminution to achieve a significantly higher throughput at the same cost and the task is to greatly reduce the investment and operating costs per ton of throughput with a throughput comparison.
  • the movable crushing jaw is fastened as an overhead design in a double-acting pendulum lever, the crushing process taking place when the pendulum is raised and lowered, thereby achieving an additional output.
  • the circular and crescent-shaped design of the crushing tools on the material to be crushed initiates a cutting and splitting process with particularly good pull-in capacity, which likewise enables a higher throughput with less drive energy.
  • the fixed crushing jaw was provided with a gap diarrhea, which enables a pre-screening and immediate separation of the crushed material to be split, combined with a significantly higher throughput.
  • the toggle lever arrangement, pressure eccentric and flywheel masses used in the crusher construction are replaced by a hydraulic pressure cylinder device, which reduces the disadvantages of the unbalanced masses and the weight of the comminution machine.
  • Figure 1 shows schematically as a side view in section and plan the hard comminution machine according to the invention
  • 2 shows the same hard comminution method according to the invention in another embodiment as a side view and partly in section and plan.
  • a crushing jaw pendulum lever which carries out pendulum or wobble movements and thereby advantageously pulls in and crushes the material to be crushed with the cutting-like crushing tools.
  • the pressure and squeeze force is generated by a hydraulic pressure cylinder device -2 on the upper end of the rocker arm -1.
  • the crushing pressure is alternately caused by the hydraulic pressure cylinder device -2, so that the movable crushing jaw -3- performs a double-acting breaking action around the pivot bearing -4.
  • There is also a vibrator unbalance machine -5 at the upper end of the pendulum lever. attached, which gives the movable crushing jaw —3— the necessary excitation frequency for the gap process.
  • the vibrator unbalance machine -5 arranged above has the advantage that the excitation frequency in the area of the crushing jaw is -3 harder.
  • the arrangement of the rotary bearing —4— approximately in the middle of the movable crushing jaw —3—, as well as the squeezing and splitting pressure caused by the hydraulic pressure cylinder device —2— and by the vibrator unbalance machine —5—, enable a high crushing performance.
  • the circulating bearing —8— with the worm gear —9— has to be mentioned additionally for the circulating breaking process.

Abstract

Un aspect essentiel d'un procédé de concassage de matières dures qui permet de réduire de manière significative les coûts d'investissement et d'exploitation par tonne produite est la mâchoire mobile à double action (3) du concasseur, reliée à un levier oscillant (1) qui reçoit le cylindre de compression hydraulique (2) ou l'agencement connu de levier à genouillère générateur de la pression d'écrasement et le moteur déséquilibré (5) générateur de la pression de clivage. Un autre aspect significatif de l'invention est l'agencement d'ouvertures (7) en forme de fentes dans la mâchoire fixe (6) du concasseur, orientée à 40° environ, qui servent à cribler les matières concassées.
