Definitions

  • the invention relates to a crushing rotor having a crushing rotor, a crushing plate and an endless conveyor that feeds the crushed material and passes over the crushing plate.
  • Crushing plants of this type which are also referred to as continuous crushers, generally have a horizontally arranged endless conveyor which simultaneously sweeps over the crushing plate.
  • the endless conveyor is designed as a chain or web chain conveyor.
  • the invention has for its object to provide a crushing plant which is versatile in use with a simple structure. This object is achieved with the features of the characterizing part of claim 1.
  • the invention has the advantage that manufacturing and maintenance costs can be saved to a considerable extent by combining different parts, namely the feeding and feeding device with the crushing rotor.
  • a continuous crusher that already has an increasing feed section of its endless chain conveyor is previously known from GB-OS 2 079 624.
  • this crusher is not provided with a crushing plate, but with a crushing roller opposite the crushing rotor, which is arranged in the lower region of the crushing rotor and at the same time serves as a deflection roller for the chain belt.
  • the present invention makes no use of these features.
  • the endless conveyor is a slat conveyor or the like, since in this way functional reliability and low wear of the system can be guaranteed.
  • the feed section can advantageously also be designed as a steep conveyor section, whereby a further reduction in the dimensions of the plant is achieved.
  • the feed section as well as the falling part of the conveyor section can, if necessary, be adjustable to adapt to different operating conditions.
  • the invention also relates to a method for operating the crushing plant, which consists in that the endless conveyor is briefly stopped when a certain predetermined crushing pressure is exceeded.
  • This method has the advantage that a larger refractive power can be effective during stopping. It is particularly advantageous if the stopping is controlled by a drive motor power control.
  • Two exemplary embodiments of the invention are shown schematically in the drawing explained in more detail below. Show it:
  • Fig. 2 shows a part of such a plant in the crushing area also in vertical section on a larger scale.
  • the crushing plant has a housing 1 which forms a feed hopper 2 in the feed area and the side walls 3 and the end wall 4 of a breaker part in the crushing area.
  • the feed section 5 of an endless conveyor 6 is arranged, which is guided with a falling part 7 in the area of the side walls 3 over two deflection rollers 8 and 9.
  • Support rollers 10 are arranged under the upper run of the feed section and 8 support rollers 11 are arranged under the common lower run of the endless conveyor 6 in the deflection area under the upper transfer roller.
  • a crushing rotor 12 Arranged between the side walls 3 is a crushing rotor 12 provided with hammers, which is opposite a crushing plate 13 extending between the deflection rollers 8 and 9.
  • the crushing rotor 12 is horizontally displaceable in order to be able to set different crushing gaps.
  • the crushed material is fed in the area of the feed hopper 2 onto the feed section 5 of the endless conveyor 6 and moves in the direction of the arrows over the deflection roller 8 in order to then fall into the crushing gap 14 formed between the crushing rotor 12 and the crushing plate 13. In crushed form, the crushed material is then fed via a chute 15 to a conveyor belt conveyor 16.
  • the endless conveyor 6 has a closed belt consisting of a suitable wear-resistant material. All soft to medium-hard materials suitable for a hammer crusher can be considered as crushed material.
  • an adjustable scraper 17 and 18 is arranged in the lower region on the circumference of the deflecting roller 9 and the crushing rotor 12.
  • the structure of the crushing plant according to Fig. 2 is the same as in the previous embodiment. Instead of a hammer crusher rotor, however, a crushing roller 20 provided with teeth 19 is used as the rotor.
  • the crushing roller 20 is also arranged to be horizontally displaceable and is thereby adjusted by a hydraulic lifting cylinder 22 acting on its bearings 21.
  • a plate belt made of steel plates is used in this crushing plant, which is provided on both sides with teeth which engage in corresponding teeth of drive wheels 27, as indicated by chain lines 23.
  • the crushing plate 13 ' is fastened to a substructure 24 which connects the bearings 25 and 26 of the deflecting rollers 8' and 9 'and thus forms a particularly rigid frame for the endless conveyor 6'.
  • the deflection rollers 8 'and 9' are each provided with a hydraulic motor as a drive unit, the speed of which can be infinitely adjusted until it comes to a standstill.
  • a drive motor power control ensures that the continuous conveyor is briefly stopped when a certain predetermined crushing pressure is exceeded, as can occur when the crushed material is too large or too hard.
  • the feed conveyor 5 is designed to rise, in particular if the subject of the invention, as preferred, is designed as a mobile crushing plant.
  • the bunker 2 can then be carried out in a simple manner without the interposition of a conveyor belt by dump trucks, front loaders, backhoe excavators or similar transport units. With this type of loading, the removal of the crushed material from the bunker can be evened out by changing the speed of the endless conveyor.
  • the feed path can also be designed to be angle-adjustable - right down to the horizontal - and possibly also have one or more stages.
  • the chassis When designed as a mobile crushing plant, the chassis can preferably be dismantled or can be designed as a self-propelled transport unit which raises the plant and can also move other devices (so-called semi-mobile plant).

Abstract

Une installation de concassage comportant un rotor de concassage (12), une plaque de concassage (13), ainsi qu'une convoyeuse sans fin (6) amenant le matériau à concasser et balayant la plaque de concassage (13) possède une structure particulièrement simple, la convoyeuse sans fin (6) formant au moins un parcours de transport (5) et ensuite, dans la zone de la plaque de concassage (13), un parcours de transport incliné. La convoyeuse sans fin (6) a ainsi la forme d'une convoyeuse à tabliers fermée. L'installation de concassage fonctionne en premier lieu de telle façon que la convoyeuse sans fin (6) s'arrête temporairement en cas de dépassement d'une pression de concassage prédéterminée.
