Pulp Thickening

Pulp Thickening, Sieve Bend Screen for Pulp Thickening, Wedge Wire Screen for Pulp Thickening, Stainless Steel Wedge Wire Screen, Wedge Wire Screen,Sieve Bend Screen,Wedge Wire 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


Sieve bend screen are widely used for washing and thickening pulp fibre in pulp and paper industries. The sieve bend screens are curved surface, constructed by stainless steel v shape profile wires, the screen slot is narrow in the above and wide in the below, they are oriented horizontally across the direction of flow, the solids are easily separated from the liquid, avoiding clogging and ensure smooth filtration.


Basic Principle


Sieve bend screen is a simple solid-liquid separation equipment, v type wire provides an efficient separation for the solids and the waste water. The pulp fiber enters the headbox, then the fiber overflows the weir, the fiber suspension align themselves in the direction of the flow, relying on centrifugal force and gravity of the water in the sieve bend screen, the water falling through, while the most of fibers that longer than the slot width will be retained on the screen surface and slide down to the bottom of the screen.
