ZNP Series Disc Thickener For Paper Pulping Line

The disc thickener is an essential unit for processing low consistency pulp, ideal for washing and thickening applications in recycled fiber lines. This disc thickener uses a multi‑disc design that significantly increases filtration area without requiring large floor space. Available with disc diameters of 2500mm or 3500mm and disc counts from 8 to 16, the disc thickener offers nominal areas from 60 m² up to 240 m². The stainless steel filter screens resist corrosion and abrasion, providing extended operational life. Its rational design for pulp cleaning and stripping prevents screen blockage, ensuring consistent dewatering performance.
