Definitions

  • the present invention relates to a method for separating feed material, the feed material having at least one ferromagnetic material fraction and one non-ferrous material fraction (that is, a non-ferrous, in particular metallic, material fraction and / or a non-ferromagnetic material fraction).
  • the aforementioned material fractions are to be understood in particular as comprising iron-containing and / or ferromagnetic or non-iron-containing feed material particles or components.
  • the aforementioned ferromagnetic feed material particles and / or constituents of the ferromagnetic material fraction do not have to consist of a ferromagnetic material, but can in particular have this.
  • a conveying flow which is made up of the material fractions to be separated off and the "residual fraction", is guided through the individual process steps in the conveying direction.
  • the conveyed flow is fed to a first separation of a first ferromagnetic material fraction, in particular by means of a first magnetic separation device.
  • the conveying flow is then fed to a second separation of a second ferromagnetic material fraction from the conveying flow, in particular by means of a second magnetic separation device. Accordingly, a two-stage separation of the ferromagnetic material fractions is provided.
  • the present invention relates to a device for performing the aforementioned method, the device having a first magnetic separation device for separating a first ferromagnetic material fraction and a second magnetic separation device for the second separation of a second ferromagnetic material fraction.
  • the device known from practice for performing the method is bulky and ultimately takes up a lot of space, so that sufficient space is required for the known device.
  • the object of the present invention is to avoid or at least substantially reduce the aforementioned disadvantages of the prior art.
  • the aforementioned object is achieved, in particular, at least essentially in that a redistribution and / or a rearrangement of the material of the conveying flow takes place between the first separation and the second separation.
  • a redistribution of the material of the conveying flow is to be understood in particular in such a way that the material of the conveying flow is mixed between the first separation and the second separation. Ultimately, the material of the conveying flow can be “turned inside out”.
  • a conveying device can preferably be provided for feeding to the first separation, wherein the conveying device can transfer the conveying flow to a further conveying device.
  • the conveying device can transfer the conveying flow to a further conveying device.
  • a redistribution and / or a rearrangement of the material of the conveying flow can take place through the design and / or the arrangement of the conveying device and the further conveying device.
  • those "lower" components of the material of the conveying flow which at least essentially face the conveying device can at least partially in the "upper" area of the conveying flow - seen in cross section, in particular transversely to the conveying direction - on the other Be arranged conveyor.
  • a rearrangement of the material of the conveying flow can contribute to the fact that at least one "lower" layer, in particular the bottom layer, of the conveying flow conveyed along the conveying device becomes an "upper” layer, in particular the uppermost layer , of the conveyed flow along the further conveying device after transfer to the further conveying device.
  • the lower layer can face the conveying device - viewed in cross section, in particular transversely to the conveying direction - while the upper layer - seen in cross section, in particular transverse to the conveying direction - can face away from the further conveying device.
  • the center plane can run centrally through the cross section of the delivery flow.
  • the center plane is oriented, at least in sections, along the conveying direction and / or divides the conveying flow, in particular along the conveying direction, into an upper and a lower part.
  • the central plane is preferably perpendicular to the cross section of the conveying flow, which is oriented transversely to the conveying direction.
  • the layers can also be intermixed during the redistribution, with the aforementioned redistribution basically remaining.

It is preferred that the conveying flow is guided as a single conveying flow, at least in the area between the first and the second separation and / or at least in sections within the process. This is advantageous for a simple process that results in a high degree of efficiency for the second separation.
  • the redistribution and / or the rearrangement preferably does not take place in and / or not in the vicinity of and / or not with the aid of sieving, sifting and / or eddy current separation (or a corresponding means, a corresponding device and / or a corresponding one Device for performing the respective process step) instead. It can also be provided that, for example, immediately before and / or after and / or during the redistribution and / or the redeployment, no comminution of components of the conveying flow is provided.
  • the redistribution or rearrangement can thus be carried out in a very repeatable and defined manner if the aforementioned influences are deliberately kept away in order to make the result of the first and second deposition at least essentially predictable and / or continuous.

  • a redistribution and / or redeployment Processing of the material of the conveying flow in particular a mixing and / or reversal of the material flow, those ferromagnetic constituents and / or particles of the material of the conveying flow that could not be separated by the first separation due to their lower arrangement facing the conveying device can be removed from of the second deposition.
  • the method according to the invention enables high ecological compatibility. A renewed passage of "the residual fraction" of the conveyed material that has not been separated can be avoided.
  • the “remaining fraction” is made up of the unseparated - “remaining” - material fraction. Non-ferromagnetic metal components can subsequently be removed from the “residual fraction” resulting after the first and second separation.
  • a targeted recovery of the metallic components can be made possible, which in particular enables a high degree of purity of the various metallic components. So far, this has not been possible in the prior art. If a metallic separation took place at all, this was due to legal requirements and / or the separation of contaminants. Otherwise, the contaminants would impair subsequent process steps. In connection with experiments according to the invention, however, it was possible to demonstrate that the targeted recovery of valuable substances as such can be used profitably.
  • the efficiency of the ferromagnetic separation of the ferromagnetic material fractions from the feed material is preferably increased by up to 70% compared to the prior art.

  • the second ferromagnetic separation in particular small parts that are smaller and / or lighter than the larger components of the conveying flow separated with the first separation can be separated.
  • the second deposition preferably takes place via a contact surface.
  • the second ferromagnetic separation is advantageously designed in such a way that the ferromagnetic components of the conveying flow which cannot or only incompletely be recorded by the first separation, in particular by means of the first magnetic separation device, can be separated in a targeted and targeted manner. This ultimately increases the degree of separation of the ferromagnetic material fraction, in particular with only a single process run.
  • the redistribution and / or the rearrangement of the material enables a compact design of the device performing the method to be ensured.
  • the space required for the device performing the method can be reduced by at least 20% and / or by up to 60% compared to systems known from the prior art. A compact arrangement of the device is thus preferably made possible.
  • the feed material is fed into a metering hopper device.
  • the feed material is added before the first separation.
  • the feed material can be temporarily stored in the dosing bunker device - that is to say stored or bunkered - and in particular also be fed to the first separation in adjustable fractions.
  • the feed material can be fed not only from above, but alternatively and / or cumulatively from the side of the dosing hopper device, whereby under "side" the longitudinal extent of the driving performing device is to be understood.
  • the feed material can be fed to the dosing hopper device in different ways.

  • a metering means for example a slide and / or a metering roller.
  • the conveying flow is fed to the first separation via a conveying device.
  • An acceleration belt can be provided as the conveying device.
  • the delivery flow can be transferred from the metering device to the delivery device.
  • the conveying flow can be equalized in the conveying direction by means of the conveying device, whereby in particular a material separation of the conveying flow takes place. As a result, the degree of separation of the first separation can be increased.
  • the conveyed flow is preferably weighed at least in certain areas on the conveyor device, in particular with a belt scale.
  • the measurement results can be used to control and / or regulate the method and / or the device.
  • the speed of the conveying device is preferably greater than the speed of the metering device, in particular by at least 20% between 100% and 500%. Accordingly, the conveying flow can be "accelerated" by being transferred from the metering device to the conveying device.
  • the conveying device is operated at such a conveying speed that when the conveyed material of the conveying flow is thrown off, a trajectory parabola between 5 and 50 cm, in particular in the horizontal direction, is brought about.
  • the metering device preferably has an, in particular controllable, belt speed of approx. 0.01 m / s.
  • the conveyor device can furthermore preferably have a belt speed of greater than 1 m / s, preferably between 2 to 4 m / s, more preferably between 2.5 to 3 m / s.
  • the conveying flow can be fed to the second separator via a further conveying device, preferably a vibration trough.
  • the further conveyor device can vibrate and / or oscillate.
  • the further conveyor device can also be designed as a conveyor belt.
  • the further conveying device which is preferably designed as a vibrating chute, can be provided for the continuous feeding of the second magnetic separating device performing the second separation.

  • the other, further components of the conveying flow are then namely arranged closer to the further conveying device after the redistribution and / or the reallocation. This mode of operation causes the second deposition to work more effectively due to the preferably provided redistribution and to deposit better than would be the case without redistribution and / or without redistribution.
  • the redistribution and / or redistribution of the delivery flow according to the invention is understood in particular to mean a particularly structured and repeatable redistribution and / or redistribution.
  • an arrangement of the at least two conveyor devices with respect to one another and / or a guidance of the conveyor flow on and / or between the conveyor device and the further conveyor device is provided.

  • the redistribution or the rearrangement represents a step in the method according to the invention that is repeatable. This means that the redistribution or rearrangement always causes the same change in the material arrangement within the cross section of the conveying flow, in particular transversely to the conveying direction, if the state before and after are compared. In particular, this naturally applies to the case that the cross section of the incoming conveying flow, in particular transverse to the conveying direction, has at least essentially a constant or continuous structure when it is observed or viewed over time at one point by a conveying device.
