Abstract

Laite, joka sisältää onton lieriömäisen rungon, ensimmäisen ja toisen liikkumattoman samankeskisen rengasmaisen lajittelusihdin, jotka on järjestetty rungon sisään, ja rungon sisällä roottorin, joka on sijoitettu sihtien väliin lietteen johtamiseksi ensimmäisen sihdin läpi ja sitten toisen sihdin läpi, roottorin toimiessa pyörimällä. Massaliete kulkee keskistä pääsisääntuloputkea pitkin, radiaalisesti ulospäin ja sen jälkeen ylöspäin pitkin roottorin sisäpuolta, edelleen sisäänpäin karkeasihtirummun läpi, ja sen jälkeen roottorin pään ympäri kulkeakseen roottorin ulkopinnan ja hienosihtirummun sisäpinnan välistä. Sen jälkeen massaliete kulkee lopuksi ulospäin hienosihtirummun läpi. Karkea rejekti, kuten oksat ja muu karkea aines, kerätään karkealajittelukammion päässä ja johdetaan pois lisäkäsittelyä varten. Hienorejekti kerätään vastaavasti hienolajittelukammion päässä johdettavaksi myös pois erikseen lisäkäsittelyä varten.
