Definitions

  • Each crushing zone has horizontal anvil bodies fixed to the container in spaced parallel relation while between the anvil bodies, and in the same horizontal plane, are rows of hammers guided for movement in the horizontal direction for beating against the adjacent sides of the anvil bodies.
  • a vibrator connected to the container supplies the power to move the hammers relative to the anvil bodies.
  • the present invention concerns a crushing device for lumpy and granular material which comprises at least one container which is arranged in a vertical direction and which comprises a plurality of crushing zones arranged in vertically spaced relationship to each other. These crushing zones have associated therewith crushing tools which are driven by a motor, especially by at least one unbalance motor. Furthermore, the present invention concerns a method of operating a crushing device of the above mentioned type.
  • Grinding devices have become known which are provided with a grinding container adapted to be subjected to circular or elliptic oscillations while in the grinding container there are loosely rotatably journalled grinding discs which are parallel to or slightly inclined with regard to the plane of oscillation of said container.
  • the said grinding discs cooperate with partitions fixedly arranged in the grinding container and have a diameter which is somewhat less than the inner diameter of the grinding container. Grinding devices of this type may be subdivided into individual grinding chambers respectively receiving a grinding disc.
  • the said partitions as well as the grinding discs are provided with per forations for the passage of the material to be crushed. With grinding devices of the above mentioned type it is also known to arrange the grinding container in upright condition and to rest the grinding discs on the intermediate walls.
  • an object of the present invention to provide a crushing device of the above mentioned general type which mill overcome the drawbacks outlined above. It is another object of this invention to provide a crushing device which will not only be simple in construction, but can also practically be employed economically for possible crushing operations.
  • FIG. 1 illustrates a longitudinal section through a crushing device according to the invention.
  • FIG. 2 represents a section taken along the line Il-II of FIG. 1.
  • FIG. 3 is a top view partially in section of a crushing zone with crushing tools according to the invention.
  • FIG. 4 represents a section taken along the line IV- IV of FIG. 3.
  • FIG. 5 is a section taken along the line VV of FIG. 3.

  • FIG. 9 is a top view partially broken away of FIG. 8.
  • the crushing device is characterized primarily in that the crushing tools are formed by a plurality of hammer-shaped bodies and cooperating stationary anvil bodies, said hammershaped bodies being formed by a plurality of bodies arranged in the respective crushing zone in and about the same horizontal plane while said hammer-shaped bodies are substantially parallel to each other.
  • the hammer-shaped bodies extend at least in the direction toward the anvil bodies under a minimum of friction and are so journalled thatthe hammer-shaped bodies are adapted to exert beating movements only in an approximately vertical direction upon the beating surfaces of the anvil bodies or beating movements correspondingly directed away from said anvil bodies.
  • the hammer-shaped bodies carry out a predetermined, i.e., directed beating or crushing movement so that the hammer-shaped bodies are able with safety with the required energy to impact against the beating surfaces of the anvil body and evaluation of the crushing surfaces associated with each other is no longer possible. Consequently, the material which is from the top of the device fed into the crushing device can with safety be grasped by'the quickly alternating movements of the hammer-shaped bodies and the material is on the beating surfaces of the anvil body crushed to the respective desired granular size.
  • the material to be crushed can, as a rule in one cycle, be ground to'powder. Since the hammer-like bodies carry out precisely directed beats, the employed driving energy is actually used for the crushing of the material fed into the device so that a device according to the present invention will over heretofore known designs realize a greater output by from 30 to 60 percent so that a correspondingly high degree of efficiency is re alized. As a result thereof, the cost per ton of material to be crushed is, in contrast to heretofore known similar designs, considerably higher than is the case with the present invention.
  • a particular advantage of the crushing device according to the present invention is seen in the fact that it can be employed practically in all industrial establishments.
  • pipe or ball mills have been employed in the cement industry which have a rather low degree of efficiency of approximately 5 percent only.
  • discharge housing For this reason it has heretofore been necessary to feed the raw cement first from a collecting silo through a scale to the mill from which the crushed material is fed to so-called discharge housing. From here, the material which to a great extent was not yet crushed was conveyed to a bucket system from which it was passed to an air sifter.
  • the degree of efiiciency of the crushing device according to the invention is so high that as a rule one single passage of the raw cement through the crushing device will suffice whereby considerable costs per ton of cement can be saved. Even when with the crushing device according to the invention the raw cement is passed through the device according to the invention more than a single time, this will be considerably less expensive than with heretofore known designs.
  • the device according to the invention can with the same advantage also be employed for crushing sand, fireproof clay, minerals, limestone, coal chemicals, slag, abrasives, colored minerals, quartzite, or the like.
  • the same can be built rather small, for instance, for use in a laboratory, it can be employed in connection with the manufacture of tablets, in other words, in the pharmaceutical industry.
  • a very important advantage also consists in that the hammer-like bodies which at a high sequence operate back and forth carry out, for instance, a plurality of beats per minute and can also be employed for intermixing substances filled into the device. Consequently, the crushing device according to the invention can advantageously be used also in the chemical industry, for instance, when making synthetic materials, and can furthermore be used in the paint industry for the crushing of paint additives.
  • At least one anvil body is arranged on each side of the hammer-shaped body.

  • the container wall of the crushing device may be used for connecting the anvil bodies.
  • the anvil bodies are formed in the shape of rods and have their upper marginal sections which face the hammershaped bodies slanted.
  • this makes it possible to employ structural standard material for the anvil bodies, and on the other hand, in view of the slanting of the anvil bodies, the advantage is obtained that material dropping upon the anvil bodies will pass toward the sides into the gaps between the anvil bodies and the hammer-shaped bodies.
  • the anvil bodies as well as the hammer-like bodies are preferably made of steel, especially hardened steel while the anvil bodies and the hammer-shaped bodies are at those ends thereof which face each other machined, for instance ground. In this way the charged goods can be crushed particularly finely, for instance, to a pulverous form.
  • the hammer-shaped bodies have those marginal portions thereof which-face the slanted portions of the anvil bodies, slanted in such a way that the hammershaped bodies in the direction of movement thereof have a substantially conical design.
  • the slanted portions of the hammershaped body extend up to the central upper width range thereof in such a way that in said intermediate width range of the hammer-shaped bodies there remains an approximately horizontal guiding surface.
  • a guiding element especially a pipe or shaft which is in a friction-free manner journalled in antifriction bearings and is rotatable about its longitudinal axis, said pipe or shaft extending over the total width of a row of hammer-shaped bodies.
  • These guiding elements will prevent the hammer-shaped bodies during the beating operations from escaping or deviating in upward direction or from edging relative to the beating path of the anvil bodies when the material is crushed.
  • these guiding elements can particularly easily move so that for the acceleration of the hammer-shaped bodies a correspondingly small impulse is required.
  • the guiding element may at its end ranges be joumalled in antifriction bearings associated with the container wall while the end sections of said guiding element protrude from the container and are held by screws or the like.
  • the anvil bodies can be disassembled from the container, for instance, for purposes of repair. It is merely necessary to loosen the holding screws and pulling the same out of the container.
  • vIt is particularly advantageous to rest the hammershaped bodies on preferably two spaced easily rotatable tubular supporting and guiding elements which extend over the total width of the respective row of hammer-shaped bodies and have their end sections protrude from the container while being held by screws or the like.

  • the guiding bearings extend over all crushing zones, they can relatively quickly be assembled, and for purposes of repair or the like can likewise quickly be disassembled.
  • a further advantage consists in that a correspondingly low number of individual elements is necessary. Consequently, it is merely necessary to keep in stock only a correspondingly small number of individual elements for cases of repair.
  • the width of the hammer-shaped bodies is considerably less than the length thereof and amounts, for instance, to from one-fifth to one-third of the length.
  • the hammer-shaped bodies have a weight of from 1 to 10 kilograms.
  • the crushing tools of one or more crushing zones are removable in such a way that within this range a free space remains.
  • this design of the crushing device according to the invention makes possible to reduce the output possibility of the crushing device by removing some crushing tools.
  • it is possible, depending on the material to be crushed to provide a free space approximately in the central range of the height of the container so that the material already treated in the upper crushing zones will be able particularly easily to distribute itself over the entire inner cross section of the container and therefore simultaneously over the lower crushing zones.

  • the material to be crushed is primarily under the influence of the gravitational force moved through the air gaps or crushing zones which form between the anvil bodies and the hammer-like bodies in view of the quick alternating beating.
