Definitions

  • the invention relates to a mobile or stationary crusher for minerals and / or their bedrock, in particular large pieces according to the preamble of the main claim.
  • a crusher loading device for the cement industry is known (brochure from Westfalia Lünen), in which the goods are placed in a bunker, from which they are brought upwards above the crusher with an inclined feed conveyor, with a corresponding one below this crusher Conveyor belt is arranged.
  • a mobile crusher system with a pre-classifying device is known ("Germanaufaufung-Technik", vol. 22, 1981, number 7, pages 362 to 366, in particular page 5).
  • the material is brought from a receiving funnel onto an obliquely upwardly directed conveyor belt, from the upper end of which the material is brought onto a pre-classifying sieve directed obliquely downwards.
  • a classifying device between the feed hopper and the conveying means that transports the material to the crusher to provide.
  • a so-called bar sizer for coarse separation is also known (Mogensen GmbH & Co KG, Wedel / Hamburg), which has bars parallel to one another, between which spaces form between, on which the oversize grain is retained and moved longitudinally, and the distance between the bars parallel to one another can be varied.
  • the rods have a downward inclination, so that the oversize slides down on the rods, which can also be set in vibration.
  • the object of the invention is to provide a crusher device of the type mentioned at the outset, in which the operating costs, including the wear of the crusher, can be reduced, the dimensioning of the crusher compared to known crusher and overall the size and the operating weight of the device can be reduced, which should be done with technically simple and easy to use means.
  • the invention provides the features of the characterizing part of the main claim. -
  • the features of the subclaims serve to improve and further develop the features of the main claim.
  • the advantage of the crusher device according to the invention can be seen in the fact that only that material (Uberkorn) not falling through the spaces between the parallel rods can be conveyed upwards into the crusher.
  • the fraction to be broken in known devices only makes up 20-50% of the total amount of goods delivered.
  • the device according to the invention therefore provides that only the coarse material remaining on the rods is to be conveyed to the level of the crusher, while the material falling through the interstices of the rods goes directly to a conveyor belt onto which the material coming from the crusher broken good ultimately falls. - During the free fall, the material that is fed into the feed hopper and falls down in the feed hopper is already separated and classified, which is supplemented when the goods hit the rod classifier.
  • the loading device is to be dimensioned smaller in accordance with the small amount of coarse material, just as the crusher needs to have a smaller width and a smaller mouth opening. This not only results in a design saving, but also in energy costs and less wear on the crusher tools during operation. - As the bar classifier in connection with the moving parts on or on the bars the feeding device takes over both the conveying and the classifying, there is a significant saving in terms of overall height, but in particular the overall length of the device.
  • the device according to the invention essentially has the feed hopper 1, the loading device 2 located below the discharge of the hopper, the crusher 3 and the conveyor belt 4, all parts resting on a chassis 5 in the embodiment according to FIG 1 in Fig. 1) a boom belt 6 can be arranged.
  • the loading device which is explained in detail in FIGS. 3 to 8, has the function of a sieve and an upward conveyor in such a way that the oversize grain reaches the belt 4 at 7 and is brought from there to the delivery belt 6 at 8.
  • the coarse pieces are conveyed to the task 9 of the crusher 3 with the aid of the loading device and broken there, after which the broken material falls on the belt 4 again at 10.
  • the loading device 2 only needs to be dimensioned to a lesser extent, since only the oversize, ie the coarse pieces, are conveyed to the crusher, as is the energy requirement the loading device corresponds to the lower material intake.
  • FIG. 2 shows a stationary device. This device can be equated with a device that can be moved on a caterpillar track.
  • the device according to FIG. 2 is distinguished from the device according to FIG. 1 by a lower overall height, since the conveyor belt 4 can be provided either between the supports 11 arranged in pairs at the same height or between the caterpillar tracks.
  • the band 4 can also experience a slight inclination with respect to the horizontal, so that overall, as stated, a lower overall height can be achieved compared to the embodiment according to FIG.
  • the simultaneously acting as a classifying and as a conveyor device 2 has a number of parallel to each other and extending from the lower end 2a to the upper end 2b of the feeding device 2 rods 12, which, for. B. may have the profile of railroad tracks.
  • the upper and lower ends of each rod 12 rest on a crossbar 13; the distance between the rods 12 can be chosen arbitrarily.
  • Spacer 14 is provided, which keeps the upper and lower ends of the rod at a distance from the neighboring rod and further prevents the rod from tilting on the cross member 13.
  • the spacers 14 are preferably designed in grid sizes and releasably connected to an angle piece 15 which is arranged on the cross member 13.
  • each side of the feed device has a U-shaped profile 17, 18, the openings of which are directed towards one another.
  • two U-shaped profiles 19, 20 are provided, the openings of which are facing away from one another.
  • the chains 17-20 can also be designed as Gall chains or link chains.
  • the tabs 31 can be provided with web bars 32, 33, between which a bar 34 is arranged in the plane of the chain.
  • the driver 35 which is arranged at right angles, can then be arranged on this in the form of a pin, a lug or a cross bar.
  • the drive of the chains is preferably arranged between crusher and loading device at about 38.
  • a hollow rod 40 which shows the U-shaped cross-sectional shape and has an upwardly open longitudinal slot 41.
  • the chain 42 is guided in the hollow rod, which can also be a link chain and to which carrier fingers 43 which protrude from the slot 41 and are provided at a distance from one another on the chain are attached.
  • the lower chain run 42a is guided in such a hollow bar 40a.
  • the two legs 44, 45 or 44a, 45a of the hollow rod can each be provided with a cover strip 46, 47 or 46a, 47a, between which the finger 43 or 43a projects.
  • a profile piece 48 connecting and supporting the two hollow bars can be provided between the two hollow bars 40, 40a.
  • the legs 44, 45 are located horizontally, so that the driving finger 43 protrudes laterally from the hollow rod 40.
  • the invention relates equally to an impact roller crusher to which the coarse material is fed from the rods 12 in its lower section.
  • This has the advantage that the coarse does not need to be conveyed upwards and, above all, that the rods 12 serve as counter bearings for the coarse pieces.
  • the webs 16 are designed and arranged accordingly. Even with a crusher with feed hopper, a horizontal and even slightly inclined arrangement of the rods 12 is possible, as with a beater roller crusher, without abandoning the principle of using the rods with their webs or fingers as a means of classification and at the same time as a means of transport.

Abstract

L'installation de concassage décrite comporte un dispositif de chargement permettant de charger un concasseur situé à une hauteur considérable au-dessus d'une trémie de chargement, et un extracteur à bande. Dans le but de réduire les coûts d'exploitation, et par conséquent l'usure du concasseur, d'obtenir un concasseur de dimensions inférieures aux concasseurs connus, et de réduire la taille et le poids en charge de l'installation dans son ensemble, le dispositif de chargement (2) permettant de charger le concasseur(3) comporte des barres parallèles (12) espacées et des traverses (16) ou similaire agencées perpendiculairement au sens longitudinal des barres (12) sur ou contre lesquelles elles glissent, et l'extracteur à bande (4) s'étend jusqu'au-dessous des extrémités des barres situées sous la trémie de chargement (1).
