Apparatus and Method for Producing Recycled Aggregate Using Waste Road Pavements

摘要

The present invention is a recycled aggregate using a closed road pavement that can reduce crushing time, increase crushing efficiency, and simplify and simplify pulverization facilities, and increase size by pulverizing waste concrete and/or waste ascon in a cooled state. It relates to production equipment and production methods. The method for producing recycled aggregate using waste road pavement according to the present invention comprises: a first pulverizing step for reducing the waste road pavement to a size suitable for secondary crushing treatment; A second pulverizing step of second pulverizing the first pulverized aggregate obtained from the first pulverizing step by a low-temperature freezing pulverization method in which the first pulverized aggregate obtained from the first pulverization step is pulverized in a cooled state using low temperature brittleness; And an aggregate classification step of receiving the pulverized aggregate by the secondary pulverization, sorting by size, and discharging the recycled aggregate.
