Hereinafter, after selecting the recycled aggregate by the particle size, it will be described an embodiment of the present invention that can be measured at a predetermined ratio to be mixed according to the site conditions.

In the yard, the recycled aggregates, which are selected by waste concrete or waste ascon, which are construction wastes in advance, are processed by particle size. In other words, waste concrete and waste ascon, which are the construction waste collected at the construction site, are shredded and produced using known techniques. That is, the coarse aggregate that is primarily crushed in the jaw crusher and passed through the primary screen is crushed in the second double jaw crusher and passes through the secondary screen, and the foreign matter sorting device sorts the foreign matter by blowing or water treatment.

In this way, the aggregates passed through the third impact crusher, cone crusher, or roll crusher after screening Schiropol or wood and other foreign matter by the third screen to produce aggregates for each particle size to be mixed in the yard.

Therefore, the circulating aggregate may be transported on the conveyor, which is the transport means 10 of the present invention, or transferred to the sorting means 20 by using a heavy machinery such as a fork lane.

The circulating aggregate is sorted by the particle size through the sorting means 20, that is, a plurality of the plurality of stacked and vibrated sorting screen (21, 22, 23) by receiving the power of the motor. That is, since the primary sorting screen 21 is composed of 25mm housing, the circulating aggregates having the particle size of the circulating aggregates are 25mm or more, and the following are passed through the lower portion. Therefore, the recycled aggregates of 25mm or more sorted to be transported to the regeneration means 70 consisting of a conveyor belt to be used again by shredding the wearing size to fit the site conditions.

In addition, the circulation aggregate of 25 mm or less passing through the primary sorting screen 21 is sorted by the secondary sorting screen 22 mounted on the lower portion again. That is, since the secondary sorting screen 22 is made of 13mm, the circulation aggregate of 25mm to 13mm is sorted by the secondary sorting screen 22, and the circulation aggregate of 13mm or less passes through the secondary sorting screen 22. do. Therefore, the circulating aggregate sorted by the secondary sorting screen 22 is transferred to the circulating aggregate box 41 by the guide means 31 along the connecting means 80 composed of the conveyor belt.

That is, since the tertiary sorting screen 23 is composed of 8mm, the 13mm to 8mm circulating aggregate is sorted by the tertiary sorting screen 23, and the circulating aggregate of 8mm or less passes through the tertiary sorting screen 23. do. Therefore, the circulation aggregate sorted by the tertiary sorting screen 23 is transferred to the guide means 32 along the connecting means 81 constituted by the conveyor belt to convey the circulation aggregate box 42.

In addition, the circulation aggregate of less than 8mm screened by passing through the tertiary sorting screen 23 is immediately transferred to the circulation aggregate 40 along the guide means (30).

As described above, the circulation aggregates of 25 mm to 13 mm and the recycling aggregates of 13 mm to 8 mm and 8 mm or less, which are stored in the circulation aggregate boxes 40, 41 and 42, respectively, are weighed by a predetermined weight so as to be mixed at a predetermined ratio. It is metered by (90) (91) (92).

At this time, when the circulating aggregate stored in each circulating aggregate box 40, 41, 42 is completed by the meter 90, 91, 92 by a predetermined amount circulating aggregate circulating aggregate at the same time (40 After transporting the recycled aggregate to the recovery means (60) consisting of a conveyor belt while the guide means (20) (31) (32) transferred to (41) (42) stops rotating in the forward direction and rotates in the reverse direction. To transfer to the transfer means 10 again, the above-described operation is repeated to transfer to the circulation aggregate box 40, 41, 42.

On the other hand, the circulation aggregates of 25 mm to 13 mm, 13 mm to 8 mm, and 8 mm or less, respectively, measured in the circulation aggregate boxes 40, 41 and 42 are transferred to the mixing means 200 through the discharge means 50 made of the conveyor belt. After being manufactured by mixing with recycled aggregate, cement, and conmix emulsified asphalt, it is transported to the site and can be used by mixing the recycled aggregate uniformly measured by particle size in the field.

In addition, the circulating aggregate boxes (40) (41) (42) when the measurement is completed by the size of the particle size is stored in the reverse rotation of the guide means 30, 31, 32 were rotated forward again and selected by the particle size size circulation Aggregate is transported back to the circulation aggregate box 40, 41, 42 along the guide means (30) (31) (32) to repeat the metering by a predetermined amount.

In addition, the circulation aggregate measured by the particle size is discharged to the discharge means 50 and transferred to the mixing means 200 and undergoes the screening process again in the reselection screen 100 formed on the mixing means 200. In other words, when the recycled aggregates are waste asphalt, aggregated together, the particle size is larger than that of the selected recycled aggregates. Therefore, the selected recycled aggregates are supplied only to standardized recycled aggregates.

The re-selected circulating aggregate is transferred to the aggregate storage bin 120 by the transfer means 110 and stored for mixing with cement and asphalt mixed asphalt.

In addition, the cement stored in the silo 130 for mixing with the circulating aggregate is supplied to the cement reservoir 140 by a screw conveyor and stored while being weighed to be mixed with the circulating aggregate, and at the same time mixing with the circulating aggregate and cement The conmixed emulsion asphalt is also weighed in the conmixed emulsion asphalt meter 150, 151, 152, and then stored in the conmixed emulsion asphalt storage container 160. At this time, a plurality of conmixed emulsion asphalt meters 150, 151 and 152 are installed to measure conmixed emulsion asphalt in order to smoothly supply the conmixed emulsion asphalt to the spiral mixer 170.

As described above, the circulating aggregate storage container, cement storage container, and condensed emulsion asphalt storage container weighed and stored in the recycled aggregate, cement, and conmix emulsion asphalt are supplied to the spiral mixer 170 to be mixed and manufactured. The prepared mixture is supplied to a truck for use on site.
