Abstract

Järjestelmä ja menetelmä lämmöneristeen kuitumaisen raaka-aineen valmistamiseksi lämpömekaanisessa prosessissa. Valmistuksessa johdetaan selluloosapohjaista haketta (1) varastoinnista (10) epäpuhtauksien poistoon; erotellaan epäpuhtaudet hakkeesta (20) ja johdetaan puhdistettu hake ilman vesipesua ensimmäiselle jauhimelle (13); suoritetaan hakkeen hiertäminen hierremassaksi ainakin ensimmäisessä jauhimessa (13) ja valitaan jauhatusolosuhteet ottaen huomioon hakkeen kuiva-ainepitoisuus ja tavoiteltu kuitumaisen raaka-aineen kuiva-ainepitoisuus; ja johdetaan hierremassa hiertämisen jälkeen kuitumassan lajitteluun (21), ja sieltä höyrynerotukseen ja sen jälkeen valmiina, tavoitellun kuivaainepitoisuuden omaavana kuitumaisena raaka-aineena (3) varastointiin.
