Definitions

  • the invention relates to a device for crushing lumpy material, in particular stone or coal, with a feed device, a rotatably mounted, drivable crushing or beating roller, which cooperates with a baffle or crushing plate for crushing the lumpy material, and with a discharge device , wherein the conveyors run in a substantially horizontal direction.
  • Such flow breakers which can also be designed as mobile devices, generally have scraper chain conveyors. With such devices, the material is fed in the conveying direction of the scraper chain conveyor. It is known to design such devices with a plurality of crushing or beating rollers, which act in succession in the conveying direction, in order to achieve a multi-stage comminution. Apart from the fact that the drive effort and the effort for the storage of a plurality of rollers are correspondingly high in such multi-stage impact roller crushers, there is a major problem that between adjacent webs of the scraper chain conveyor rock plates can form, which as flat plates below the respective impact or crushing rollers leave the crusher uncrushed.
  • the invention now aims to provide a simple device of the type mentioned at the beginning, with which such plate-shaped parts can also be comminuted without any appreciable additional outlay.
  • the invention essentially consists in that in addition to the horizontal feed and feed device in the area of the crushing or beating roller another feed device opens, the axis of which is the axis of rotation of the crushing or Impact roller crosses or cuts.
  • this additional feeding device is oriented essentially perpendicular to the direction of travel and conveying direction of the scraper chain conveyor, and this additional feeding device allows material which has not yet been sufficiently shredded to be further shredded and shredded using the same crusher.
  • a breaker or a baffle plate known per se is advantageously arranged in the region of the mouth of the second feed device.
  • the oversized and thus not sufficiently comminuted parts conveyed away by the scraper chain conveyor in the direction of passage can be separated in a simple manner in a screening device downstream of the removal device, the screen overflow advantageously being able to be fed to the second feeding device via a further conveyor device. All that is required for the pre- and post-comminution is a crushing or beating roller, and the remaining coarse parts can be fed in via the further feed device designed as an inlet hopper.
  • the adjustable breaking comb or the adjustable baffle plate can advantageously be set essentially perpendicular to the conveying direction of the scraper chain conveyor, and can advantageously be adjusted, for example with a hydraulic cylinder-piston unit.
  • a further adaptation to the desired size reduction performance can be achieved in that the mesh size of the screening device is adjustable.
  • the crushing or impact roller works in this design in its lower part facing the scraper chain conveyor as a coarse shredder and in its upper area adjacent to the baffle plate or breaking comb as a secondary crusher or small comminution. Both of these working methods can be carried out with a single crushing or beating roller.
  • a further crushing or beating roller is arranged below the mouth of the further feeding device.
  • the fact that the further crushing or beating roller is arranged below the mouth of the feeding device means that this further crushing or beating roller is not in the main conveying flow but only in the area of the oversize feed. Oversize can therefore be selectively smashed with an optimal effect, and such a device can thus be designed so flexibly that no additional power is consumed when there is less oversize.
  • the further crushing or beating roller arranged at this point can easily be switched off with a correspondingly small amount of oversize, without the conveying flow being inhibited, as a result of which drive power can be saved.
  • the additional crushing or beating roller can advantageously have a smaller diameter than the underlying crushing or beating roller with which the primary comminution takes place. In this way, the remaining grain size after passing through the primary rotor or the main crushing or beating roller can be better taken into account.
  • the design is advantageously made such that the additional crushing or beating roller interacts with a breaking comb or a baffle plate, which (r) from the breaking comb or the baffle plate of the underlying crushing or beating roller is different and separately adjustable.
  • the secondary rotor shreds oversize and the oversize can, depending on the design of the crushing chamber, work against crushing arms, crushing combs or baffle plates and additionally or exclusively against the primary rotor as a counter-impact roller.
  • Such a training also has the advantage that not only a selective re-shredding of already pre-shredded material is made possible, but it can simultaneously process different materials, which have different behavior when crushing or shredding, at the same time, with the additional Materials other than the main feed material are mixed in. It is thus possible to shred the main feed material with the primary rotor located below and, at the same time, to add different material crushed to the main stream of the primary rotor via the second feed device.
  • the design is particularly advantageous in such a way that the further crushing or beating roller is adjustably mounted transversely to its axis of rotation.
  • the distance between the impact circle of the secondary rotor and the primary rotor can be kept adjustable by a simple adjustment device, whereby in connection with an adjustment drive for a breaking comb or a baffle plate, which interacts with the secondary rotor, a double adjustment possibility and optimization of the crushing space in adaptation to the feed material can be made.
  • the secondary rotor can work as an impact or milling drum if the drive is designed accordingly.
  • the crushing tools such as the striking pieces, blow bars and the like of the primary rotor, are formed symmetrically, so that they form a working surface in both directions of rotation.
  • FIG. 1 shows a schematic overall view of the plant according to the invention
  • FIG. 2 shows an embodiment of the crusher with a breaking comb
  • FIG. 3 shows a modified embodiment with an adjustable baffle plate
  • FIG. 4 shows another embodiment with an additional impact roller.
  • a roller crusher 1 is shown schematically, which is designed as a continuous crusher.
  • the material is fed in the direction of arrow 2 onto a scraper chain conveyor 3, the material to be comminuted passing under a crushing roller 4 and being comminuted.
  • the material which may not be sufficiently comminuted, is separated in a downstream sieve 5, the sieve overflow, which contains the oversize, being fed to a further feed device 7 of the roller crusher 1 via a conveyor device, which is indicated schematically by the arrow 6.
  • the axis of this further feed device which is indicated by 8, crosses the axis of rotation 9 of the crushing roller 4, and a separate fine comminution can be carried out with the same crushing roller 4.
  • the fine grain which has the desired grain size, is drawn off as a sieve passage from the sieving device 5 at 10.
  • FIGS. 2 and 3 Detailed illustrations of the flow breaker 1 can be seen in FIGS. 2 and 3.
  • the screen overflow reaches the conveyor device 6 an inlet funnel 11.
  • a breaking comb 12 is provided, which is essentially perpendicular to the conveying direction of the scraper chain conveyor 3.
  • the material which is indicated schematically at 13, is roughly crushed below the crushing roller 4 and discharged to the screening device via the scraper chain conveyor 3.
  • the oversize is finely comminuted between the crushing roller 4 and the breaking comb 12, so that overall a largely uniform grain size distribution corresponding to the requirements can be achieved.
  • an adjustable baffle plate 14 is provided instead of the breaking comb 12.
  • an impact roller 4 is used here, the oversize particles forming the screen overflow being in turn fed by the conveying device 6 to the inlet hopper 11 or the additional further feed device.
  • the direction of conveyance of the scraper chain conveyor 3 is indicated by the arrow 15.
  • the baffle plate 14 is adjustable via a hydraulic cylinder-piston unit 16.
  • the beater roller 4 rotates much faster than a crushing or chisel roller, and especially with such a design it is essential that a protection is provided in the direction of the material feed, for example formed by curb chains 17, which prevents comminuted parts from flying back to the material feed. Also in the beater roller 4 in FIG. 3 there is first a preliminary comminution in the running direction or conveying direction 15 of the scraper chain conveyor 3, whereupon the additional fine comminution takes place between the baffle plate 14 and the beater roller 4.
  • FIG. 4 shows a further embodiment of a continuous crusher 1, the main crushing roller 18 of which is 19 designated axis of rotation is rotatably driven.
  • the conveyor is formed by scraper conveyors, which are indicated schematically at 20 and are arranged on the bottom of a housing 21 for the crusher.
  • the feed material passes through a chain guard curtain 22 and is indicated schematically at 23.
  • the comminuted material in the conveying direction 24 passes through a discharge device 25 onto a sieve, the sieve overflow being returned to the additional feed opening 27 of the flow crusher via an additional conveyor belt 26.
  • a secondary rotor or a further striking or breaking roller 28 is rotatably mounted, the axis of rotation of which is designated by 29.
  • the axis of rotation 29 is adjustably mounted in the sense of the double arrow 30 in order in this way to be able to adjust the normal distance from the axis of rotation 19 of the primary rotor 18.
  • a crushing plate 31 which is indicated by dashed lines, can interact with the primary rotor 18.
  • a crushing plate or a crushing comb which can also be designed as an impact rocker, is provided, which interacts with the further crushing or beating roller and is designated by 32.
  • the adjustment drive for this additional baffle plate or rocker arm is indicated schematically at 33.
  • the drive of the two crushing or impact rollers 18 and 28 can be derived from a common motor 34 via belts.
  • the drive of the additional crushing or impact roller 28 is advantageously formed separately from the drive of the crushing or impact roller 18.
  • Such an additional drive motor is indicated schematically at 35.
  • a chain curtain 36 corresponding to the chain curtain 22 on the entry side is provided in order to provide protection against broken particles flying away.
