Description
Claims (1)
- 폐지를 조펄프화하기 위해 비이터를 사용하고 본문에 상술한 바와 같이 장치상의 특징을 갖는 1차 선별기에서 펄프화되지 않은 섬유물질과 다량의 가벼운 이물질이제거되고 하이드로 사이클론을 이용하여 무거운 이물질이 제거된 반스터프를 보조회로로 보내어 진동선별기를 거친다음 2차 선별기의 배출관이 1단계에서의 진동선별기보다 작은 구멍을 갖는 다음 단계의 진동선별기로 연결되어 여기서 나오는 반스터프가 본문에 상술한 바와 같은 장치상의 특징을 갖는 하이드로 사이클론에 연결되어 다단 선별 및 이물질 제거를 수행할 수 있으며 분리된 섬유질이 다시 처리공정으로 순환되는 것을 특징으로 하는 폐지처리 방법.
