Abstract

노후된 콘크리트폐기물의 수거과정(1)과, 상기의 수거과정(1)에서 크라셔를 부착한 포크레인 등으로 상기의 수거콘크리트에서 철근 및 기타 잡철을 분리하는 제 1 잡철분리과정(2)과, 상기의 잡철분리과정에서 철근등의 잡철이 제거된 폐콘크리트를 분쇄기(36"X46"JAW)를 투입하여 분쇄시키는 1차분쇄과정(3)과, 상기의 1차분쇄된 폐콘크리트가 이송수단(콘베이어)에 의해 이동되는 과정에서 혼입되어 있는 철근토막이나 기타 잡철물을 제거하는 제 2 차 잡철제거과정(4)과, 상기의 2차 잡철제거과정(4)은 콘베이어로 이동되면서 일정 부위의 콘베이어 위에 설치된 고성능의 전자석에 의해서 잡철물 등을 제거하는는 전자석 철편제거과정(5)과, 상기의 철편제거과정을 거치고 콘베이어로 이송되는 폐콘크리트에서 재차 잡철 등을 제거하는 수작업에 의한 잡철제거과정(6)으로 이루어진다. 상기의 2차 잡철제거과정(4)에서 잡철이 완전히 제거된 상대의 분쇄된 폐콘크리트에서 일정규칙 이하의 크기를 갖는 골재를 출하시키고 일정 규격 이상의 골재는 선별하여 재차 분쇄할 수 있도록 하기 위하여 철망의 구멍크기가 규격화되어 있는 스크린을 이용하여 선별하는 스크린선별과정(7)과, 상기의 스크린선별 과정에서 선별된 골재를 일정크기의 세골재로 하기 위하여 재차 분쇄하는 2차 분쇄과정(8)과, 상기의 과정에서 2차분쇄된 골재를 크기별로 선별하는 선별과정(9)으로 콘크리트 재생골재가 생산되는 것을 특징으로 하는 콘크리트 폐기물을 이용한 재생골재 생산방법에 관한 것이다.A first step of separating iron (2) to separate the reinforcing bar and other scrap metal from the collected concrete by using a process of collecting old concrete waste (1) and a fork crane having a crusher attached to the collecting process (1); The primary grinding process (3) of grinding the waste concrete from which the scrap iron such as rebar is removed in the process of separating the scrap iron is added to the grinder (36 "X46" JAW), and the first milled waste concrete is conveyed by means of conveying means (conveyor). The second scrap iron removal process (4) for removing the reinforcement fragments and other scrap metal that is mixed in the process of moving by the) and the second scrap iron removal process (4) is moved to the conveyor on the conveyor Electromagnet scrap removal process (5) for removing the miscellaneous metals by the high-performance electromagnet installed, and the miscellaneous iron by manual work to remove the scrap iron again from the waste concrete to be conveyed to the conveyor through the above iron strip removal process It consists of a coarse process (6). In the secondary debris removal process (4), the aggregates having a size less than a predetermined rule are shipped from the crushed waste concrete of the counterpart in which the debris has been completely removed, and the aggregates having a predetermined size or more are selected to be crushed again. A screen sorting process (7) for sorting using a screen having a standardized hole size, a second milling process (8) for crushing again to make the aggregate selected in the screen sorting process into fine aggregates of a predetermined size, and It relates to a method for producing recycled aggregate using concrete waste, characterized in that the recycled aggregate is produced as a screening process (9) for selecting the secondary milled aggregate by size in the process of.
