Abstract
코팅된 폐지 펄프 재고 재생 공정으로부터의 배출 스트림에서 과립 물질을 제조하는 방법에서, 펄프 재고는 체별되는데 배출 스트림이 체를 통과하고 긴 섬유가 체상에 잔류하여 종이 제조에 사용된다. 배출 스트림내의 고체 물질은 부유기(18)에 의해서 분리된다. 배출 스트림으로부터 수분이 제거되어 배출 스트림의 점조도가 조형용 진흙(40)의 점조도로 증가된다. 배출 스트림이 집괴기(46)로 이동하여 거기서 불규칙적이나 대략 구형인 균일한 과립을 형성한다. 그 후 과립은 건조기(50)내에서 건조되어 95%를 초과하는 고체 함량을 가지게 된다. 이 방법 및 장치에 의해 형성된 과립 물질의 공정 방법을 수행하는 장치 및 성질이 또한 명세서에 개시되어 있다.
