Application:

　　ZNX series inclined screw thickener is a gravity-filter. It lifts stock through a rotating screw roll inclined about 60° in the pipe-shaped filter drum. It is used for thickening and washing in low consistency and medium consistency range of waste paper pulping process and it is also suitable for thickening and washing pulp such as sulfate wood pulp, mechanical pulp, and chemi-mechanical pulp, etc.

　　Design Features:

　　ZNX series inclined screw thickener consists of screw roll，brush,screen,frame, inlet and outlet device as well as the driving device, etc. Pulp enters to the screen basket via level-regulating box from lower part of thickener.The white water is draining out through screen as a result of increased pressure and level difference between inside and outside of the screen when the screw is rotating.The thickened paper stock is shredded by blades on upper end of the screw and discharged out of the trough.The white water is collected in the filter tank and flows out of the white water outlet.

　　The capacity and outlet consistency of the inclined thickening can be varied with the size of screen holes, the length and pitch of the screw and rotation speed, etc. In general, while handling with waste paper pulp, the thickener shall keep the screen holes at ɸ1.5～ ɸ2mm，inlet consistency is 2～4% and outlet consistency is 10～12%

　　Simple structure; easy, safe and reliable in operation and maintenance,high capacity and less area requirement.

　　The inclined screw thickener's output or consistency can be changed by means of the level box's pulp consistency and the pulp level difference.The inclined screw thickener's output or consistency can be changed by means of the level box's pulp consistency and the pulp level difference.
