RECYCLED AGGREGATE PRODUCTION SYSTEM USING CONSTRUCTION WASTE, FOR RECYCLING CONSTRUCTION WASTES IN RECYCLABLE CONDITION THROUGH CRUSHING, SELF-SELECTION AND SCREENING

摘要

PURPOSE: A recycled aggregate production system using construction wastes is provided to prevent the destruction of the nature and the waste of resources due to the reclamation of the construction wastes and to recycle the screened recycled aggregates in recyclable condition through crushing, self-selection, screening and drying. CONSTITUTION: A recycled aggregate production system using construction wastes comprises a hopper(100) through which the construction wastes are fed to a first crusher, a first crusher(200) crushing the construction wastes in the size less than 200mm, a metal separator(300) separating metals from the firstly crushed wastes, a first screen(400) screening the wastes 40-50mm of aggregates from earth according to the grain size, a second crusher(500) crushing the 40-50mm of aggregates in the size less than 40mm, a second screen(600) screening the aggregates having size less than 25mm from the aggregates discharged from the second crusher, a drying unit(700) drying the aggregates using hot air, and a third crusher(800) sampling the aggregates of the size less than 5mm.
