Paper/cardboard suspension dewatering device comprises formed roller (apart from open roller) opposite to the roll of second roller in its filtering direction where the lateral sides of formed roller and first roller are at a distance

摘要

The jet material exhibits a thickness of (8-25 mm). The formed roller (16) is designed such that two filters (7, 9) are led (after passing it) across the first roller (3). The roller has more zones in a range of 50-90%. The distance (A1, A2) between rollers (3, 4, 16,) is adjustable and the sieve size screens are attached to suction and blowing zones. The impinging line of the jet material lies on the second filter after flow line of the roller.
