According to the present invention, when the waste asphalt crushed in the crusher is separated and discharged by softening AP oil (Asphalt oil) in a dryer, cooling of the circulating ascon to cool the softened AP oil on the surface of the separated aggregate discharged Apparatus, in particular, to collect the waste asphalt packed on the road to separate the separated aggregate heated and separated in the dryer to prevent re-bonding of the softened AP oil during cooling, as well as the separated aggregate separated and discharged from the dryer It relates to a circulating ascon cooling apparatus that enables the mass production of recycled aggregate and circulating ascon by cooling the separated aggregate in the amount of.

In general, asphalt paved roads have different sizes of aggregates mixed with AP oil depending on the surface layer and substrate.

Therefore, as described above, in case of repairing or repairing for a long time, the paved asphalt had to be separated from the road surface and disposed of.

As the above-mentioned waste asphalt has a great impact on environmental pollution, although the government has made various efforts to promote the recycling business from private operators, the construction company that paves the asphalt road recycles the waste asphalt or waste asphalt. It is a situation to avoid using aggregate.

In other words, when new aggregates and recycled aggregates are mixed in a certain ratio, the waste asphalt is collected and crushed to about 25 cm for primary crushing, and then crushed for surface layer of 13 mm or less and base layer of 19 mm to 40 mm for secondary crushing. When the recycled aggregate is mixed with new and AP oil to produce ascon, the aggregate recycled from waste ascon is not a perfect new aggregate but contains AP oil, and many aggregates are mixed and mixed. Since the quality of the malignant aggregate is degraded, when mixing with new aggregates, the porosity increases, as well as the quality of the new ascon occurs.

Therefore, suppliers or contractors who supply new materials do not trust the use of recycled aggregates that recycled waste asphalt, thereby avoiding the use of waste, resulting in an increase in waste asphalt and waste asphalt, resulting in enormous capital costs for disposal. It damages and adversely affects the surrounding environment.

Particularly, in the case of suppliers supplying new goods, even if the recycled aggregate recycled waste ascon is used, if the quality of the product is guaranteed, it can not only save a lot of costs, but also collect the profits generated from collecting the waste asphalt and produce new goods. It can generate huge profits from the raw material cost which is saved while reducing the cost, so it can have the effect of gaining profits for both environment, supply, and profit. Therefore, it is required to request that the products produced by recycling waste ascon be used in manufacturing new materials. do.

Accordingly, in the 'circulating ascon production apparatus and method thereof' filed by the applicant on February 04, 2005, the waste asphalt is separately collected as shown in FIG. 1, and the shredder 1 is shredded to an appropriate size. In the process of classifying for surface layer, it is heated in the dryer (2) to soften the AP oil of the waste asphalt, and the cold air is blown to the separated aggregate which is transferred to the vibration conveyor (3) to prevent re-bonding of the softened AP oil. Although the method of the present invention has been prevented from re-bonding the softened AP oil even by the applicant of the above application, as the amount of the separated aggregate that is discharged in a large amount and the separated aggregate to be cooled largely contrasted, the softened AP oil is rapidly There has been a need for an equal amount of separated aggregates to be cooled and discharged by cooling and cooling aggregates to be cooled.

That is, since the time required for cooling the separated aggregate heated and discharged is longer than the time required for heating, heating and cooling are imbalanced with each other, resulting in a decrease in the production of circulating ascon.

The present invention devised by the above-mentioned needs and demands enables the cooling of the heated separated aggregate discharged by being heated in the heating dryer during the manufacturing process of the circulating ascon and the discharge of the separated aggregate from the heating dryer at least at the same time. By allowing all the separated aggregates to be cooled down and sorted, the purpose is to enable the discharged separated aggregates to be rapidly introduced into the cooling process.
