Disc Filter

ZNP Series Disc Filter Application ZNP Series Disc Filter is mainly used to wash and thicken pulp in pulping and papermaking process. It works by level difference of stock between inside and outside of disc wire. The pulp at consistency of 0.8 1.2% enters the vat then attached to disc sector, filtrate is guided by hollow shaft and discharged out at two ends. Stock attached on sector is knocked off by high-pressure shower. The thickened stock at consistency 3 4% flows over the plate of adjusting valve then into discharge chamber where it is let out. The rotation speed of main shaft can be adjusted for required outlet consistency and capacity. Advantages of ZNP Series Disc Filter Less space required. Sector is made of stainless steel with good corrosion resistance. Due to the structure of disc sector, the filtering area is large, allowing large volume filtrate handled. Filtrate consistency is lower than cylindrical wire thickener. Mechanical maintenance and spare parts preparation is easier.
