Claims (7)

1. Fremgangsmåde til behandling og til genindvinding af fibre til papirfremstilling eller fremstilling af isoleringsmateriale fra et fiberholdigt materiale, navnlig fra gammelt papir, hvor det fiberholdige materiale ved en stoftæthed på 40 % til 99 % nedbrydes i et tværstrømsnedbrydningsaggregat under en kontinuerlig slagpåvirkning.
2. Fremgangsmåde ifølge krav 1, kendetegnet ved en stoftæthed af fibermaterialet, som skal nedbrydes, på mindst 50 % til 95 %, og særligt foretrukket fra 80 % eller 85 % til 95 %.
3. Fremgangsmåde ifølge krav 1 eller 2, kendetegnet ved, at fugtigheden af fibermaterialet, som skal nedbrydes, og/eller temperaturen og/eller støvudviklingen ved nedbrydningen af fibermaterialet styres eller reguleres ved hjælp af indsprøjtning via dyse eller indsprøjtning af vand.
4. Fremgangsmåde ifølge ét af kravene 1 til 3, kendetegnet ved en udskillelse af smudsfraktioner, navnlig af tungt smuds og let smuds, under eller efter nedbrydningen.
5. Fremgangsmåde ifølge krav 4, kendetegnet ved en efter udskillelsen anbragt udblødning i en udblødningsbøtte.
6. Fremgangsmåde ifølge ét af kravene 1 til 5, kendetegnet ved, at fibermaterialet, som skal behandles, tilsættes kraftfiberpapir, som nedbrydes sammen med det øvrige fibermateriale.
