Technology for pulp sheet drying plants
ANDRITZ provides turnkey market pulp drying plants, as well as individual technologies for each market pulp drying/baling process.
A market pulp sheet drying plant usually starts at the high density storage tower directly after the bleach plant of the fiberline.
The pulp sheet drying plant comprises pulp screening/cleaning, dewatering, drying, baling, and finishing operations. ANDRITZ is well equipped to supply individual equipment or turnkey plants.
Modern pulp sheet drying plants are equipped with a screening/cleaning system in order to achieve the highest pulp cleanliness.
Perfect sheet formation and highest wet sheet tensile strength are important factors in the availability and successful operation of a large single pulp drying line. ANDRITZ pulp dewatering technologies include:
- Twin Wire former
- Twin Wire press
- Fourdrinier machine
