Pressure Screen for Wood/Straw Pulp Processing

China Leizhan M.C Pressure Screen is international advanced paper pulp screening equipment. Our company adopts advanced technics and designs this new type pulp mid consistency screening equipment. It is used for wood/straw pulp hot screening and chemical, paper pulp coarse and fine screening.

Usage of M.C. Pressure screen

Pressure screen serve to filter out contaminants and foreign matter as well as separate the fibres. The aqueous fibre suspension is pumped through the screen at pressures and temperatures of approx.

This pressure screen has better adaptation, less power &water consumption and high efficiency when compared with common low consistency pressure screen.

Operating of Pressure Screen

ZNS Pressure screen screens paper pulp continuously with pressure in a sealed room. During operation, pulp flows along tangential direction into separation chamber which is on the top of the machine. Heavy impurities are separated in the effect of centrifugal force, then will subside in Heavy slag tank and be deslagged from heavy slag mouth. Pulp overflow round-shape flash board and flow to the screen space between screen basket and turbine. Eligible fiber flow through screen basket and expel from accept mouth. Unqualified fiber will subside to the tank bottom and discharged from slag pipe. Dilution pipe is installed Right in front of slag pipe, it is used to adjust tailing pulp consistency. Many raised impellers are welded on turbine inside screen basket , when rotating, the impellers will generate negative pressure, which can clean the screen basket and prevent jam of it .
