The returning operation of the sorting belt 237 is performed during the sorting operation by the above operation, so that when the sorting of the sorting belt 237 occurs, the sorting belt 237 is returned to the original position without stopping the operation .

Operation of the apparatus for producing recycled aggregate according to one embodiment of the present invention will now be described.

According to the embodiment of the present invention as described above, the construction waste firstly crushed while passing through the jaw crusher 10 passes through the screen 14 and passes through the first conveying conveyor And the construction waste having a predetermined particle size or more filtered through the screen 14 is discharged through the first belt conveyor 25 disposed between the trommel 30 and the jaw crusher 10, 30).

In the middle of the first belt conveyor 25, a contaminant conveying conveyor 26 for conveying contaminants separated and sorted by an operator is arranged so as to intersect. A waste transportation vehicle enters the ground on the side of the outlet end of the contaminant conveying conveyor 26 (28).

So that the contaminants discharged through the contaminant conveying conveyor 26 can be immediately loaded into the contaminant collecting tank 28 or the waste conveying vehicle entered into the contaminant collecting tank 28.

The magnetic separator 20 is disposed on the line of the first belt conveyor 25 located between the jaw crusher 10 and the trommol 30 to separate and sort the iron foreign substances contained in the firstly crushed construction waste.

Therefore, the construction waste, which is a crushed material supplied to the trommel (30), does not contain iron foreign matter, that is, reinforced steel when the concrete is laid.

When the magnitude of the construction waste supplied to the magnetic force selection unit 20 is equal to or greater than the set value, an operation signal is transmitted from the control unit 700 according to the magnitude signal transmitted from the sensing unit 276 and power is supplied to the adjustment motor 274 .

When the adjusting motor 274 is driven, the power of the adjusting motor 274 is transmitted to the slide bar 272 by the driven gear 274a and the follower gear 272b.

At this time, since the rotation of the slide bar 272 is restricted by the protrusions 272a inserted into the first protruding / retracting link 254 and the second protruding / retracting link 256, the main gear 274a And the adjusting motor 274 are rotated, so that the connecting pipe 252 rotates.

When the connecting pipe 252 is rotated, the first up / down link 254 and the second up / down link 256 are coupled to the upper and lower ends of the connection pipe 252 by the first screw thread 254a and the second screw thread 256a, Is inserted into the connecting pipe (252).

As the length of the mounting part 250 is shortened, the mounting frame 234 is elevated, so that the gap between the magnetic force selecting part 20 and the first belt conveyor 25 is widened, 1 < / RTI > belt conveyor 25 as shown in FIG.

The iron foreign substance passing through the gap between the magnetic force selecting section 20 and the first belt conveyor 25 is attached to the bottom surface of the sorting belt 237 by the magnetic force provided from the electromagnet 20a, The foreign matter of the iron is moved to the outside of the first belt conveyor 25 by the pressing belt 237a which is moved in the lateral direction by the rotation of the driven roller 238. [

The foreign matter moving to the outside of the first belt conveyor 25 is caught by the end of the mounting frame 234 and can not rotate like the sorting belt 237 but falls outside the first belt conveyor 25.

Thereafter, when the size of the construction waste passing through the first belt conveyor 25 becomes small, the control motor 274 is rotated in the reverse direction according to an operation signal transmitted from the sensing unit 276 through the control unit 700, 250 to reduce the distance between the magnetic force sorting unit 20 and the first belt conveyor 25.

Therefore, it is possible to prevent the malfunction that the magnetic force is not transmitted to the iron foreign substance passing through the magnetic force selecting unit 20, and the foreign matter of the iron is passed without being bonded to the magnetic force selecting unit 20.
