Definitions
- the invention relates to a method for shredding particular metal-containing solid according to the preamble of claim 1 and an apparatus for performing the method.
- a solid according to the genus so-called large shredders are used, with which the solid is comminuted to a piece size up to 250 mm. Since the solid has a proportion mainly of iron and non-ferrous metals, the comminuted and so far separated material is recycled, typically a smelting furnace.
- the problem described in the generic prior art does not arise in the known from the cited documents method.
- the invention has for its object to further develop a method of the generic type so that the shredding solids are optimized for further use. This object is achieved by a method having the features of claim 1 and by a device for carrying out the method.
- This device has a housing, with a first chamber in which the supplied solid, which is initially precompressed, is crudely crushed or shredded in a first shredding stage, as it were.
- a Granulier founded is arranged by means of the previously coarsely crushed and separated solid is further comminuted, so as to come to a desired piece size, which ultimately in a subsequent material separation as a recovered metal, in particular aluminum , Steel and copper.
- the comminution takes place by means of a positioned in the first chamber grinder and the granulating, which is also designed as a grinder.
- the grinder and the granulator are operated by a common drive, wherein the
- the grinder and the Granulier listening are part of one and the same tool, in which the crushing tools of the grinder of the first chamber and the crushing tools of Granulier listening the second chamber are assigned, each as an area of the common tool.
- the crushing tools of the grinder and granulator may be the same or different.
- the pre-compression of the solid takes place by means of a single or double drive roller.
- the coarsely crushed material through the grinder is discharged by means of a ceiling and / or floor grate and a
- Discharge chute and a Austragsschwingrinne removed wherein the crushed solid separated into a light fraction and a heavy fraction and fed, for example, a magnetic drum and separated into magnetic and non-magnetic material.
- the non-magnetic material is then fed to a screen, the oversize solid being fed to the granulator.
- the light fraction is fed to the granulating device by means of a rotary separator or a cyclone in which both streams of material, that is to say oversize as it were, as well as the light fraction, are further comminuted in a granulation process.
- the mentioned Austragsschwingrinne which removes the material flows from the first and second crushing stage separated, can be part of a
- the device for pulse direction consists of a pressure chamber below a vibrating channel with a grate over which the crushed material is passed.
- the light material guided over the grate is brought by means of an impulse into the field of vision of a viewing hood located above the vibrating channel, within which a separation takes place depending on the speed of vision of light and heavy material.
- Figure 1 shows the inventive method in a flowchart
- Figure 2 shows an apparatus for performing the method in a
- FIG. 3 shows a section through the device of Figure 2 along the line A-A
- Figure 4 shows a section through the device of Figure 2, corresponding to the line B-B
- FIG. 5 shows a device for pulse direction in a schematic side view.
- FIG. 1 shows a flow chart of a method for comminuting, in particular, metal-containing solids, which will be described again below.
- a grinder 2 and a granulator 3 are arranged, wherein the grinder 2 in a first chamber 15 and the
- Granulating device 3 are positioned in a second chamber 17 ( Figure 2).
- a solid for example, a motor vehicle to be scrapped, fed to the grinder 2, this solid can be previously compressed.
- the solid is shredded in the grinder 2 before it reaches a discharge vibrating trough 5.
- the non-magnetic material is separated below a predetermined piece size, while the material is fed to the granulating device 3 above a predetermined piece size.
- the shredder light fraction extracted in the pulse separator 7 is now likewise fed to the granulating device 3, specifically by means of a rotary sieve separator or cyclone 8.
- both material streams are subjected to a granulation process and further comminuted.
- This crushed material is passed to a discharge vibrating trough 6, which is part of a second
- Impulssichters 7 ' is detected in the only dusty and very light material components with low visual speed and deposited in a filter 9.
- the Austragsschwingrinnen 5 and 6 are preferably combined to form a unit, in particular integrally formed.
- the granulated mixed fraction passes through the Austragsschwingrinne 6 to a magnetic drum 1 0, where it is magnetically separated.
- the material mixture passes to a sieve 1 1, in which the larger pieces separated and the granulator 3 are fed again.
- FIG. 2 shows a device according to the invention for shredding metal-containing solids, in particular, with the housing 1, which is subdivided by a dividing wall 12 into a first chamber 1 5 and a second chamber 1 7.
- the granulator 3 is arranged in the first chamber 1 5, the grinder 2 and in the second chamber 1 7, the granulator 3 is arranged. Both the granulator 3 as well as grinder 2 are part of a common tool that is operated by a drive, shredded in the first chamber by the grinder 2 of the solid and in the second chamber 1 7 through the
- Granulating device 3 is granulated.
- each crushing devices such as hammers or similar crushing tools, which are actuated via a common drive 14.
- the supplied solid is first coarsely crushed, this solid is pre-compressed by means of a single or double drive roller 1 3.
- the material shredded in this respect is discharged via a ceiling and / or floor grate 16 and passes via a discharge shaft 25 (FIG. 3) into a shredder discharge 22 of an outlet vibrating channel 21.
- the Austragsschwingrinne 5 the shredded material passes to a magnetic drum 1 0, by means of which the material is magnetically separated
- the granulator 3 i. the second chamber 1 7 is closed by a bottom 1 9, while opposite a ceiling grille 1 8 is provided, the grate openings are sized small, whereby the granulation process is made possible.
- the granulation process can be controlled.
- the finely disintegrated and partially sphered material after granulation is discharged via the ceiling grate 18 and passes via a discharge chute 26 (FIG. 4) to a granulate discharge 23 of the outlet vibrating chute 21.
- the aforementioned pulse direction 7 is illustrated in a schematic view in FIG.
- the pulse direction 7 has a pressure chamber 27, which is arranged below the discharge vibrating channel 5.
- a grate 28 is inserted, which is flowed through at high speed of the pressure chamber 27 outgoing air.
- the material is separated from light and heavy.
- some of the dust generated during shredding is extracted.
