Abstract

Et apparat for fremstilling av et granulat fra brukt termoplastisk materiale, såsom plastfolie, og et vannholdig tilsetningsmateriale, såsom sagmugg. Apparatet omfatter en med kniver (9, 30) forsynt istykker- skjæringsenhet (1) for termoplasten, en med istykkerskjæringsenheten (l) kommuniserende skrueekstruderenhet (2) til plastifisering avtermoplasten samt en granule- ringsenhet (3). Istykkerskjæringsenhetens (1) kniver (9), som er roterende, er anbrakt på en i et avlangt kammer (7) montert sylinderenhet (8). Knivenes (9) festepunkter ligger fortrinnsvis på minst en skruelinje på sylinderenhetens (8) overflate. Istykkerskjærings- enheten (1) er montert parallelt med og utenfor skrue- ekstruderenheten (2), slik at sistnevnte kan avgi varme til førstnevnte. Istykkerskjæringsenheten (1) har minst to temperatur- og/eller fuktighetsfølere (I5a - 15g) i kammeret (7) og har dessuten varmereguleringsorganer som styres av temperatur- og/eller fuktighetsfølerne (15a - 15g), for sikring av en rolig fordampning av vannet i tilsetningsmaterialet, slik at sistnevnte er tørt når det passerer fra istykkerskjæringsenheten (1) over i skrueekstruderenheten (2). Skrueekstruderenhe- ten er forsynt med minst to termostatstyrte (19a, 19b, 19c) varmebånd (18a, 19b, 18c). Herved oppnås en meget pålitelig fremstilling av granulatet uten risiko for dampeksplosjoner i skrueekstruderenheten.
