Abstract

Fremgangsmåte og anordning for styring av separatorer som brukes til å separere fibersuspensjoner, er vist. I et system hvor minst en separator brukes til å separere en fibersuspensjon i fraksjoner inneholdende komponenter av matesuspensjonen, benyttes sensorer til å generere informasjon relatert til et karakteristikon hos minst en av de fraksjoner som dannes. Den således genererte informasjon blir så brukt til å styre separatorenes driftsparametere. Ifølge ytterligere utføringsformer av oppfinnelsen, gir sensorer informasjon til å kontrollere som i sin tur styrer separatorene.The method and apparatus for controlling separators used to separate fiber suspensions are shown. In a system where at least one separator is used to separate a fiber suspension into fractions containing components of the feed suspension, sensors are used to generate information related to a characteristic of at least one of the fractions formed. The information thus generated is then used to control the separator operating parameters. According to further embodiments of the invention, sensors provide information to control which in turn controls the separators.
