Abstract (en)

[origin: WO9901610A1] The invention relates to a device for dehydrating solid-based liquid suspensions, specially fiber-based suspensions. The suspension is dehydrated between two bands (4, 5). A dehydration zone is configured as a wedge-shaped area. The invention is chiefly characterized in that the upper and/or lower deflection roller (21, 22) is designed as a tightening roller at the beginning of the wedge.
