Saveall/Thickening

Saveall/Thickening, Wedge Wire Screen for Fiber recovery, Wedge Wire Screen Tube for Pulp Thickening, Wedge Wire Screen for Fiber Fractionation, Drum Screen for Pulp and Paper

Objective


Pulp is commonly made from wood or recycled fibre, there are many stickies, plastic, specks shives, bark fragments and debris in pulp fibre. In order to enhance the quality of pulp destined for a wide range of pulp and paper products, washing and thicking pulp fibre is a essential process in pulp and paper production.


Solution


Wedge wire screen tube is a kind of pressure screen basket, it is one part of the paper pulp pressure screen. The pressure screen baskets are mainly used for pulp thickening in the pulp and paper making process. The screen made of v shape wire, the slot is narrow in the above and wide in the below, thus enables the water for easy through the slit, and can be separated qualified fiber from the impurities and fiber bundles effectively, thus improves the screening efficiency and quality of the pulp.


Basic Principle


Fiber suspension enters pressure screen baskets, under the rotating function of pressure screen baskets and centrifugal force effect, removing suspended solids from water. The filter operate under pressure, which forces water through the slit, while the fiber larger than wide of the slots are blocked on the screen surface.


Benefits


High fiber recovery efficiency

Promotes good fiber and rejects separation

Low maintenance requirements and costs

Long service life

Less loss of fiber


Application


Fiber recovery: rich white water

Pulp thickening: cleaner rejects

Fiber fractionation
