Next, the operation and effects of the shredding / selecting device for construction waste according to the embodiment of the present invention configured as described above will be described.

First, when construction waste is input to the first shredder 110 through the first hopper 112, the construction waste is shredded by the first shredder 110 to discharge the first waste through the outlet of the first shredder 110. Foreign matter contained in the construction waste shredded by the first shredder 110 while being discharged onto the conveyor 120 and transported by the first discharge conveyor 120 (for example, a relatively large and long metal and waste wood) Etc.) are manually removed and dropped onto the 40 mm metal wire mesh 221 of the first sorter 130.

However, the belt 141 is suspended between the first driving wheel 140b fixed to the rotating shaft 140a of the first driving motor 140 and the first driven wheel 143 provided on the first eccentric shaft 142. As the first driving motor 140 rotates clockwise in FIG. 5, the first driving wheel 140b fixed to the rotation shaft 140a of the first driving motor 140 is clockwise in FIG. 5. Rotational force of the first driving wheel 140b is transmitted to the first driven wheel 143 through the belt 141 so that the first driven wheel 143 rotates clockwise in FIG. 5. The first sorter 130 swings while drawing an oval in a clockwise direction so that the aggregate and the foreign matter slide down.

Accordingly, the aggregate having a particle size of 40 mm or less in the shredded construction waste dropped from the first discharge conveyor 120 on the 40 mm metal wire mesh 131 of the first sorter 130 is the 40 mm metal wire mesh 131. ) 8 mm metal wire mesh 132 installed below the 40 mm metal wire mesh 131 so as to fall down, and fine powder having less than 8 mm of grain size and residing soil passes through the 8 mm metal wire mesh 132 to collect the fine powder Collected in the hopper 133 is discharged to the stone powder / xantho collection position by the stone powder / xantho conveyor 240 through the outlet of the stone powder / xantho collection hopper 133.

In addition, among the aggregates having a particle size of 8 mm to less than 40 mm that do not pass through the 8 mm metal wire mesh 132, an aggregate having a particle size of less than 8 mm to 25 mm is a 25 mm metal wire mesh 134 installed under the 8 mm metal wire mesh 132. It is collected in the first aggregate collection hopper 135 by passing downward to the bottom, and the particle size is less than 8mm to less than 25mm by the first aggregate discharge conveyor 250 through the outlet of the first aggregate collection hopper 135 Aggregate having a particle size of less than 25 mm to less than 40 mm that is discharged to an aggregate collection location and that does not pass through the 25 mm metal wire mesh 134 is collected in the second aggregate collection hopper 136 and the second aggregate through the discharge port.
