ZNW series cylinder wire thickener consists of wire mould, pressure device of pressure roll, scraper knife device and driving device, etc.Low consistency stock(0.5~1%)is fed from inlet into its cylinder trough where the stock is attached to the surface of wire mould along the direction of the low-speed rotation of wire mould. The stock water is drained by the level difference(1/5~1/2 cylinder diameter)between inside and outside of cylinder. The filtered stock is carried in the rotating wire cylinder at low speed and further pressed and dewatered to 5~6% by the roll on gravity. The pressed stock is removed from roll by a scraper knife and drop in outlet.Wide adaptability to different kinds of pulps, low consistency dewatering, high dewatering ratio, high output, and using different wire mesh for white water quality control.Output per square meter of wire area will be less 1 ton for masson pine GP, 2 tons or more for chemical pulp and 1.5~2 tons for straw pulp per day.
