Parameter
Product Photo



The rollers of a twin-roll pulp washer are essential components that directly influence the machine's pulp washing efficiency, squeezing performance, and durability. These rollers are designed to work under high-pressure conditions, ensuring effective washing and dewatering of pulp in the papermaking process.
Structure and Features of the Roller:
Core Material:
- Made of high-strength steel or corrosion-resistant alloys, ensuring durability and stability in harsh operating conditions.
- The material is resistant to wear and corrosion from chemicals used in the pulp washing process.
Surface Design:
- The roller surface is typically grooved or perforated to facilitate liquid drainage during the dewatering process.
- High-precision finishing ensures uniform pressure distribution and effective pulp squeezing.
Hollow Structure (Optional):
- Some rollers have a hollow structure to allow internal liquid flow for temperature control or filtrate discharge.
Bearings and Seals:
- Equipped with high-performance bearings to support smooth rotation.
- Seals prevent contamination and ensure consistent operation under high pressure and moisture.
Roller Size:
- The dimensions, including diameter and length, are customized based on the capacity and design of the twin-roll washer.
Functions of the Roller:
Pulp Washing:
- The rollers help in removing residual chemicals and impurities from the pulp by applying pressure and facilitating the flow of clean washing water.
Dewatering:
- They effectively squeeze the pulp to remove excess water, preparing it for further processing.
Filtrate Separation:
- The grooved or perforated surface of the rollers allows the filtrate (extracted liquid) to flow through and be collected for reuse or disposal.
Mechanical Support:
- The rollers provide stable mechanical support to the pulp washer, ensuring consistent operation.
Applications:
- Pulp and Paper Industry:
Used in the washing and dewatering of chemical pulp, mechanical pulp, or recycled fibers. - Bleaching Process:
Essential in removing bleaching chemicals and improving pulp quality.
Key Advantages:
- High durability and wear resistance for long service life.
- Efficient dewatering and washing to enhance pulp purity.
- Low maintenance requirements due to robust design.
- Customizable surface patterns for different pulp washing needs.
