Twin wire press upgrades

  • Conversion from low-consistency (LC) to medium-consistency (MC) headbox for an increased production rate.
  • Self-adjusting floating wedge section compensates variations in the pulp feed, such as flow or consistency swings, thus ensuring a higher production rate.
  • Stainless steel dewatering boards minimize the risk of deformation and plugging of the plates and keep the operational performance of the press up. With the ANDRITZ Fishbone design the open dewatering area is even increased.
  • Upgrade of the S-section to a press nip for higher dewatering capacity and higher wire life time.
  • Wear-resistant stainless steel-clad rolls are virtually maintenance free. Grooved rolls can be installed for higher dewatering demands. Read more
  • Split press section ensures self-adjusting pressure distribution across all press nips for optimum dewatering.
  • Replacement of the stiff press water doctor with a new, flexible, and exchangeable design provides easy maintenance and blade exchange.
  • Drive roll press nip results in increased final dryness and minimizes the risk of wire slipping.
