Abstract

Highly efficient and environmentally friendly mechanical process was developed for the higher recovery rate and productivity in the recycling of waste jelly-filled communication cables. Only the simplest mechanical method was designed and built for a continuous process, further proved experimentally along with the addition of several parts such as brush-type rollers and scrappers. In this process, the recovery rate and productivity were 98% and 55 Kg/hr respectively. This process is thought to be simple but highly advanced method for the commercialization of green process.

폐 젤리충진 케이블로부터 고순도 구리 와이어를 높은 회수율과 생산성으로 회수할 수 있는 친환경 공정을 개발하였다. 두 롤러(roller) 사이에 폐 케이블을 공급해주고 롤러의 밀착 압력이 외피(주로 polyethylene)의 인장강도 이상이 되면 자연스럽게 구리 심선과 외피로 분리되도록 한 단순한 기계적 방법만을 적용한 친환경 공정을 개발하였으며, 연속공정을 위한 세부 요소기술을 접목하고 이를 실험적으로 검증하였다. 연속공정을 통한 구리 와이어 평균 회수율은 98% 이상, 처리속도는 55 Kg/hr이었으며, 상업화 공정을 위한 진일보된 공정으로 평가될 수 있다.
