Definitions

  • Processing plant in particular crushing plant, in particular rock crusher, with a feed unit that can be filled with material to be crushed, with a screening unit having a pre-screen being arranged behind the feed unit or in the feeding unit in the conveying direction, with the pre-screen being able to be set in oscillating motion by means of an oscillating drive, and with part of the supplied material being fed to a subsequent process unit, in particular a crushing unit, via the screening unit and another part being screened out in the screening unit.
  • Such treatment plants are used for various purposes. They are used, for example, to screen out rock material in crushing plants. Such crushing plants can be used for crushing rock material and can be used either as mobile or as stationary plants.
  • the material to be crushed is fed into the system via the feeding unit.
  • Excavators are usually used for this purpose. Starting from the feed unit, the material to be shredded is conveyed to the screening unit with a conveying device.
  • the screen unit can have different designs. Designs are known in which the screen unit forms a simple conveying trough which is provided with openings in order to achieve a screening effect (grate trough). Furthermore, constructions are already known in the state of the art in which a screen deck is used as a circular or elliptical vibrator.
  • One or more additional screen levels are installed below a conveyor chute.
  • the rock material is fed to a crushing unit via a conveyor.
  • the crushing unit can be a jaw crusher.
  • the upstream unit grate channel or screen
  • part of the material fed in is screened out, this screened-out fraction is bypassed in the crushing unit bypassed so that it does not burden the crusher.
  • Sidebands are usually used for this.
  • the user now has the opportunity to choose whether he wants to run one or the other mode of operation. To do this, he has to set an adjustable flap of the conveying device either to the bypass position or to the conveying position.
  • Such a plant is from DE 10 2017 112 091 A1 known.
  • EP 0 382 922 A2 discloses a jaw crusher with a crushing aggregate. Crushed material can be fed to this crushing unit via a crushed material feed device.
  • the crushed material feed device has a feed hopper 20 and an oscillating conveyor associated therewith.
  • a bar screen is arranged downstream of the vibrating conveyor in the transport direction. With the bar screen, a rock fraction can be screened out of the supplied material in front of the crushing unit. The rock fraction, which was fed to the crushing unit via the bar screen, is crushed there and placed on a discharge belt. The material screened in the bar screen area is also fed onto the discharge belt.
  • a crushing plant that works in a similar way is out DE 41 38 597 A1 known.
  • a jaw crusher is used as the crushing unit, to which the material to be crushed can be fed via a feed conveyor.
  • the feed conveyor has a Ground on, which can be in the form of a bar grating.
  • another screen is arranged, which is part of the feed conveyor.
  • the bottom and the other screen are excited with a vibration exciter so that material can be screened out.
  • a first rock fraction is screened out in the area of the bar grate and a second rock fraction is screened out in the area of the further screen.
  • the first rock fraction reaches a crusher discharge belt.
  • the second rock fraction is crushed in the crushing unit and then also reaches the crusher discharge belt.
  • This object is achieved in that another screen is arranged in front of the screen unit in the conveying direction and is driven by a vibration exciter, and that a control device is provided by means of which the vibration drive and the vibration exciter are controlled separately from one another.
  • the screening unit is preceded by a further screen results in an effective enlargement of the total available screen area. This increases the dwell time of the filling material in the screen area, which makes improved screening possible.
  • the screening process is significantly more effective and the load on the downstream process unit is therefore lower.
  • the different excitations can be selected in such a way that they develop an optimal screening effect adapted to the respective filling material.
  • any type of unit with which a screening effect can be achieved can be used as a preliminary screen or as an additional screen. Accordingly, roller grates, grate channels or the like can also be used in particular for this purpose.
  • a transport section of the feed unit in particular a feed chute, is arranged in the conveying direction before the further screen, and that the transport section can be made to vibrate independently of the pre-screen, preferably of the vibration exciter. Accordingly, the transport section and the preliminary screen can be optimally adjusted to the tasks to be performed by these structural units.
  • the vibration of the transport section can be designed in such a way that an optimal conveying effect and an even distribution of the material fed in is achieved. Accordingly, the vibration of the pre-screen can be designed for optimized screening.
  • the feed unit and the further screen can form a structural unit which is connected to the vibration exciter and is driven by it to generate vibratory movements. Accordingly, the feed unit and the additional screen can be driven by a common vibration exciter. In addition, these assemblies can then be combined to form a compact unit.
  • the vibration drive and the vibration exciter are controlled by the control device in such a way that the pre-screen and the additional screen and/or the pre-screen and the transport section of the feed unit each perform an oscillating movement, with the oscillating movement of the pre-screen and the oscillating movement of the additional screen or the oscillating movement of the pre-screen and the transport section differing in the form of excitation, excitation intensity, excitation direction and/or excitation frequency.
  • This makes it possible to set the pre-screen and the transport section or the pre-screen and the additional screen individually and suitably for the upcoming screening task.
  • a processing plant according to the invention can be such that the additional screen is driven by a linear vibrator in order to set the additional screen into linear vibrations or into essentially linear vibrations in the conveying direction.
  • an oscillation that supports the conveying effect is set with the additional screen and the transport section of the feed unit that is optionally coupled thereto. In this way, the transport of the filling material to the preliminary screen can be supported or effected.
  • the pre-screen pre-screen to be driven by a circular vibrator in order to set the pre-screen in circular vibrations or rotating vibrations and for the screen surface of the pre-screen to run inclined in the conveying direction, with the screen surface of the pre-screen preferably forming an angle in the range between 6° and 10° with the horizontal.
  • the circular vibrations or the rotating vibrations lead to an optimized screening effect in the area of the preliminary screen.
  • the screen surface of the pre-screen is inclined relative to the horizontal in accordance with the above information.
  • the angular range specified above has proven to be particularly advantageous when used in rock crushing plants.
  • a processing plant can be designed in such a way that the feed unit has a feed section with a base, which is in particular part of a feed chute, the base being merged into the screen surface of the additional screen, that the additional screen is interchangeably coupled to a mechanical interface of the feed unit by means of a fastening section, and that the interface is equipped to accommodate a closed base instead of the additional screen.
  • the treatment plant can be adapted to the desired application as a kit, depending on the task at hand. If a filling material is fed in that requires an intensive screening effect to relieve the downstream process unit, the additional screen can be installed.
  • the feed unit has side walls that delimit a conveying chute laterally and in the conveying direction, and that the side walls extend at least partially in the conveying direction to the side of the additional screen in order to delimit a continuous transport area.
  • a compact design can also be realized as a result.
  • the additional screen has a free end that faces the pre-screen, that the pre-screen has a feed area that faces the free end of the additional screen, that the feed area is offset downwards in the direction of gravity, forming a step compared to the free end of the additional screen, and that the height of the step is preferably at least 50 mm, particularly preferably in the range between 50 mm and 500 mm.
  • the filling material is circulated during the transition from the further screen to the pre-screen, thereby further improving the screening effect.
  • a conceivable variant of the invention is such that a diverting element is arranged in the direction of gravity below the further screen, by means of which the partial fraction screened out by the further screen can be transported away, that the diverting element is preferably set in oscillating motion together with the further sieve by the vibration exciter, and that the diverting element is preferably designed as a chute, for example made of rubber material.
  • the sieved fraction of the filling material can be reliably transported away from the working area of the further sieve via the deflection element. In particular, this prevents the machine from being impaired by dirt.
  • the diversion element can be set in an oscillating movement together with the further screen, a transport movement induced by the oscillating movement can also be used for transport on the diversion element. Since a common vibration exciter is used, the number of parts is reduced. In addition, the diverting element then does not have to have a particularly strong inclination to support the transport effect, so that a low overall height can be achieved. A simple construction results when using a chute made of rubber material as the discharge element.
  • a further embodiment of the invention can be such that an additional screen deck is arranged below the pre-screen, in particular below an upper deck of the screen lining of the pre-screen, to which the fraction screened by the pre-screen (upper deck) is at least partially fed, and that a transport section for discharging the material screened by the additional screen deck is arranged below the additional screen deck.
  • additional screen deck With the additional screen deck, another fine sub-fraction can be screened out of the material that has already been screened, which can also be separately conveyed out of the working area of the machine.
  • the discharge element extends below the further screen and the preliminary screen. In this way, the material screened out by both screens can be discharged together via a single discharge element.
  • the deflection element has an end section which is guided to the lower screen deck in order to direct the material screened out by the further screen to the screening area of the lower screen deck.
  • the material screened out by the further screen can then be subjected to a further screening process on the lower screen deck in order to be able to screen out a fine partial fraction here as well.
  • the preliminary screen has a discharge area at its end facing away from the further screen, which is led to a crushing unit of a crushing plant, the crushing unit preferably having a stationary crushing jaw and a movable crushing jaw opposite it, and that a crusher discharge belt or another suitable means for transporting away the material crushed by the crushing unit is arranged below the crushing unit.

  • the coarse rock material is broken in the converging fissure.
  • the crushed and crushed rock material leaves the crushing unit 40 on the bottom side and falls onto a crusher discharge belt 60 due to the force of gravity.
  • the crushed rock material is discharged via the crusher discharge belt 60 and piled up next to the crushing plant 10 .
  • a magnetic separator 61 is provided on the crushing plant 10 in the area of the crusher discharge belt 60 . This is arranged above the material flow, which is guided on the crusher discharge belt 60 . Metal parts in the material flow are magnetically attracted by the magnetic separator 61 and separated from the material flow.

  • a preliminary screen 32 e.g. upper screen deck
  • Part of the rock material is screened out. These are pieces of rock which, because of their size, do not have to be sent through the crushing unit 40 since they are already of a size which roughly corresponds to the size of the rock which is broken by the crushing unit 40 .

  • the filling material is circulated here, which leads to an improved screening effect in the subsequent screening process on the pre-screen 32.
  • the preliminary sieve 32 is preferably set in torsional vibration with the vibration drive 38 . A good screening effect is achieved in this way. Due to the inclination of the pre-screen 32 relative to the horizontal, a transport effect is supported, as has already been described above.
  • Another partial fraction is screened out of the filling material. This screened-out partial fraction falls onto the screening element of the screening lower deck 34. Another screening process takes place here, as has already been explained above.
  • the additional screen 24 can be dismantled. In the process, it is detached from the mechanical interface 26 and removed. Instead of the additional screen 24, a closed base can then be attached to the mechanical interface 26. This closed floor then guides the filling material directly onto the pre-screen 32.
  • a control device is provided. With this, the preliminary sieve 32 and the further sieve 24 can be controlled separately from one another using the vibration drive 38 and the vibration exciter 25 . In this way, a significantly improved screening effect is achieved.
