Press roll pair - for dewatering cellulose etc

摘要

Press roll pair is connected downstream of a dewatering press in which cellulose or other fibrous material supported on a sieve or between two sieves is passed between horizontally supported roll pairs. At least one roll of the press roll pair is provided with continuous grooves running from one end of the roll to the other and inclined to the roll surface generator. In particular the grooves intersect each other.
