Paper Pulp Screening Pressure Screen Basket

Screen Basket for Pressure Screen

The screen basket is installed in pressure screen. It's main function is to screen and filter the fibers in the pulp fiber suspension, remove impurities and non pulp concentrations, thereby improving the quality of the paper. At the same time, the screen basket can also control production capacity and pulp concentration by adjusting the internal and external liquid level difference and the rotation speed of the screen basket.

Screen Basket Type

Accroding to prdoction process ,the screen basket mainly have two types, slot type and drilled hole type screen basket. Drilled hole screen basket is mainly used for coarse screening, slot screen basket is mainly used for fine screening. 

According to the pulp flow method, the screen basket can be divided into inflow screen basket and outflow screen basket, the flange in the outside is outflow screen basket, the flange in the inside is inflow screen basket.
