Definitions

  • the invention relates to a jaw crusher with vertical or horizontal loading of the crusher chamber, which narrows in the direction of material flow, and which is formed between two crushing jaws, at least one of which is provided with a crushing stroke drive which engages on the rear side of the crusher jaw facing away from the crushing chamber.
  • a known jaw crusher of this type (DE-PS 38 03 496) has a crushing jaw rocker suspended at one end in the crusher housing and having an eccentric drive as the crushing stroke drive.
  • Such an eccentric drive consists of an electric motor built on the crusher, which rotates an eccentric shaft via a belt drive, which is provided with large flywheels arranged on the side. Starting from the eccentric shaft, the circumferential movement is converted into a back and forth movement with which the crushing jaw rocker is acted upon via a pressure plate.
  • Such an eccentric drive has proven itself for breaking hard rock and for crushing recycling material. Due to the selected drive, however, a correspondingly stable design and foundation are necessary.
  • the great powers of the Eccentric drives driven by centrifugal masses also require complex overload protection in order to prevent the system from breaking due to force when the crushing jaw swing is blocked. Finally, because of the many exposed moving parts, this form of drive is of operational reliability that can be improved.
  • Jaw crushers with a hydraulic drive are also known (DE-AS 11 29 040). Overload protection is of course also required here. Because of the hydraulic drive, an overpressure valve serves as overload protection, which automatically reduces the pressurization when an overload is detected and then follows a new breaking stroke.
  • jaw crushers double rocker crusher, DE-OS 16 07 610
  • both crushing jaws delimiting the crushing space are designed as crushing jaw rockers.
  • the elements of the power transmission from one jaw to the other can be used for overload protection.
  • Such jaw crushers are used for pre-crushing and post-crushing.
  • correspondingly expensive drives were previously considered necessary, because otherwise the necessary refractive powers could not be applied.
  • the drives lead to corresponding sudden stresses on the mechanically moving parts, which in turn have to be diverted into the housing and the housing foundation.
  • Correspondingly stable and then complex designs are required.
  • the object of the invention is to design a jaw crusher which is particularly suitable as a secondary crusher in such a way that the stress on the housing and the foundation is reduced so that the crushing result remains the same, so that civils can be found here with a simpler and lighter design.
  • This object is achieved by the invention characterized in the claims.
  • the invention is based on the surprising knowledge that when using a crushing stroke drive consisting of two vibrators mounted side by side and transversely to the direction of material flow on the back of the crushing jaw, a crushing result that is at least satisfactory for secondary crusher is achieved with considerably smaller impact loads.
  • the use of two vibrators is suitable to allow such coordination and superimposition that, on the one hand, sufficient refractive power is ensured for the respective breaking process, but, on the other hand, the stress on the housing is caused by the introduction at different points of, if necessary, different forces with different vibration patterns and foundation can be reduced so that a considerably lighter design is sufficient.
  • This requires the use of more than one vibrator. Because the vibrators can work together with regard to the refractive power, but with regard to the load on the housing and the foundation, the variety of design options with two vibrators can result in considerably more favorable conditions.
  • one of the two vibrators directly in the area of the outlet gap of the crushing chamber, where the greatest crushing forces are to be applied.
  • the other vibrator is expediently arranged next to the material flow direction.
  • the two vibrators are each provided with an independently adjustable unbalance. In this way, optimization can be easily achieved by appropriate setting by appropriate adjustment of stroke frequency and stroke amplitude of the individual vibrators, which act on the crushing jaw at different points with different leverage.
  • a further advantage is obtained when the crushing jaw is suspended in the housing via springs with adjustable spring forces. Because in this case there is another possibility to intervene in the vibration behavior of the jaw crusher via the springs and their reaction forces to the refractive forces exerted by the vibrators.
  • the springs also have the advantage that in a certain, relatively large refractive power range, overload protection with the corresponding design effort is not required. By opening the crushing jaws against the spring forces and expanding the crushing chamber, unbreakable material can escape and leave the crushing chamber without destroying the jaw crusher.
  • the closed design of the vibrators also brings safety-related advantages. Exposed belt drives and mechanically moving parts as in conventional eccentric drives no longer occur here. It is also obvious that because of the possibility of controlling the vibrators according to frequency and amplitude when designing the jaw crusher as a horizontal crusher, the drive by the two vibrators can be used not only for the application of the crushing forces, but also for the crushed material to transport the corresponding amplitude overlay through the crushing chamber, i.e. to ensure the flow of material. Furthermore, due to the drive by the two vibrators, feed chute and discharge chute, insofar as they are integrated in the system, can also be used for screening due to the vibrating drive, without the need for separate sieve constructions.
  • one or a plurality of movable crushing jaws can additionally be acted upon by a hydraulic cylinder.
  • the entire crushing jaw is adjusted with the vibrators built on its back.
  • the hydraulic cylinder can only serve to adjust the crushing gap according to the requirements of the material to be manufactured.
  • the crushing power of the vibrators can also be increased according to requirements by additional hydraulic cylinders acting on the crushing jaw. It is of course possible to provide a conventional overload protection by pressure limitation with the help of a pressure relief valve. If the movable crushing jaw is designed as a crushing jaw swing, then a hydraulic cylinder is sufficient. With more complex storage of the crushing jaw in the housing, several hydraulic cylinders can also engage on one and the same crushing jaw.
  • a jaw crusher 10 is here in an embodiment with a vertical crushing chamber 12 and an overhead loading mouth 14.
  • a crusher jaw 18 is fixedly mounted in the crusher housing 16.
  • this jaw 18 can be moved in the Crusher housing 16 suspended and provided with the vibrator drive explained here only for the other jaw 20.
  • the jaws 18 and 20 are provided with replaceable wear parts 22. They are arranged in such a way that the crushing chamber 12 narrows in the direction of material flow, that is to say from top to bottom, and reaches the narrowest point in the region of the outlet gap 24 located below.
  • the movable crushing jaw 20 in turn has wear parts 22 on its side facing the crushing chamber.
  • vibrators 26 and 28 On the back there are two vibrators 26 and 28.
  • the construction of such vibrators is known. They essentially consist of an electric motor, the two shaft ends of which are guided out of the housing and provided with unbalance weights. The unbalance weights are interchangeable and their relative position can be adjusted on the shaft. If the same unbalance weights are arranged diametrically opposite each other on both shaft ends, the vibrator runs unbalanced.
  • the shaking frequency and shaking stroke can be influenced by adjusting the angular position of the radially arranged weights. Both are transferred directly to the movable jaw 20 via the vibrator housing of the vibrators 26, 28.
  • the vibrator 26 is placed on the crushing jaw 20 directly in the area of the outlet gap 25 in such a way that the shaft of the vibrator lies parallel to the level of the crushing jaw 20, but transverse to the direction of crop flow through the crushing chamber 12.
  • the second vibrator 28 is arranged directly next to the vibrator 26, but is located from the exit gap 24 in the direction of the loading mouth 14. It is thus offset from the direction of the crop flow. Otherwise, its arrangement corresponds to that of the vibrator 26.
  • the connecting line of the shafts of the two vibrators 26 and 28 is therefore parallel to the crushing jaw 20.
  • the vibrators can be of different sizes, but are preferably the same, as indicated in the figure Size selected for both vibrators 26 and 28. It is obvious that the vibrators influence the movement behavior differently due to their different points of attack on the jaw 20. It is also obvious that the vibrators 26 and 28 can be adjusted independently of one another, so that this already provides options for setting the refractive power, the breaking stroke and the breaking frequency, as well as for directional superimpositions in the direction of crop flow, which provide support for the conveyance. This is of little importance in the case of vertically situated crushing chamber 12. However, it can replace its own conveyor, for example a chain conveyor, with the crushing chamber 12 lying horizontally.
  • the crushing jaw 20 is suspended in the crusher housing 16 by means of two spring assemblies, namely a spring 30 and a spring 32. These springs can also be adjusted by appropriate pretensioning (as indicated in the figure) and thus provide an additional possibility of influencing the vibration behavior of the crushing jaw 20 Influence of the drive of the vibrators 26, 28.
  • the spring 30 acts in a direction of action which represents the extension of the connecting line of the shafts of the two vibrators 26 and 28.
  • the spring 30 is parallel to the jaw 20 behind this. It is arranged above the vibrators 26, 28, as the figure shows.
  • the other spring 32 engages with the perpendicular direction of action on the crushing jaw 20 in such a way that it is perpendicular to the center of the connecting line of the shaft axis of the vibrators 26 and 28. Their point of attack on the crushing jaw 20 is thus, as can be seen in the figure, on the back of the crushing jaw between the vibrators 26 and 28.
  • the springs 30 and 32 are present in pairs, so that they are on the side outside the crushing chamber reach past this. In this way it is also possible to arrange the spring 32 in the manner shown in the figure so that it also reaches past the crushing jaw 18 on the outside and is thus arranged laterally outside the crushing chamber 12 starting from the crushing jaw 20. Both springs 30 and 32 or the majority of the corresponding springs are supported on the crusher housing 16 accordingly.
  • the figure further shows that the crushing jaw 20 has at its lower end a bend 34, on which the piston rod 36 engages a hydraulic cylinder 38, which is provided with a power connection 40 for supplying power to the valves integrated in the hydraulic cylinder 38.
  • the hydraulic cylinder 38 is horizontal, as shown in the figure. If the crushing jaw 20 is designed as a crushing jaw rocker with a suspension at its upper end, the crushing jaw 18 can thus be moved towards the crushing jaw 20 by the hydraulic cylinder 38 and thereby reduce the outlet gap 24 or increase the crushing force on the material to be crushed which is guided through the crushing chamber 12 .
  • the hydraulic cylinder 38 thus produces a basic setting which overlays the breaking action of the two vibrators 26 and 28.
  • hydraulic cylinders 38 are also provided and can act on the jaw 20 at appropriate points. It is also obvious that the hydraulic cylinders 38 can be provided in the usual way with an overload protection in the form of a pressure relief valve.
