I. Summary
1. Function:
PL multi-disc filter mainly suit to:
(1) Recovery white water during paper-making
(2) Thicken pulp during pulp-making
2. Accommodation and advantage
   This machine can help you gain good economical benefit and social benefit.
   If used in white water recovery, it can not only recovery fiber from the white water, but also make water recycle so that reduce the water consumption and eliminate the pollution of white water drainage.
   If used in pulp thickening, it can make clean filtrate recycle and reduce water consumption.
   ---- Compact structure, lower space limit, and high produce capacity
   ---- Simple fan-like structure, changeable filter area and changeable output
   ---- High automation degree, reliable and easy operation
   ---- High filtrate clarity, filtrate recycled, save water resource
   ---- Lower energy consumption and high fiber yield
3. Structure principle
The disc axle on vat is comprised of hollow axle and disc flakes fixed on the hollow axle. Each flake is made up with fan-like plates, which connect with channel in axle through short tube. Division section of distributing valve corresponds to channel of main axle that formed filtrate passage.
