Product Description

The Sizing Roll is an essential component in paper pulp stock preparation, designed with a specialized stainless steel shell for exceptional flexibility and durability. Its advanced construction features a uniform modality, a large tapping area (up to 50%), and a specially designed buffer layer that effectively disperses stress and resists mechanical shock during operation.

This innovative roll design ensures efficient dehydration with relatively low nip pressure, preventing dandy marks and paper sheet crushing. As a result, the paper sheet quality is significantly improved, and felt longevity is extended. Additionally, the Sizing Roll offers a longer grinding cycle, along with excellent wear and chemical resistance, making it an ideal choice for consistent and reliable performance in paper-making processes.

Product Advantage

  • Enhanced Paper Quality: Prevents dandy marks and sheet crushing for high-quality paper production.

  • Efficient Dehydration: Large tapping area and low nip pressure optimize dehydration without compromising sheet integrity.

  • Durable Design: Stainless steel shell ensures flexibility, uniformity, and resistance to wear and chemicals.

  • Stress Resistance: Buffer layer disperses mechanical stress and shock for smooth operation.

  • Extended Lifespan: Prolongs felt life and reduces maintenance needs with a longer grinding cycle.

  • Cost Efficiency: Durable construction and reduced downtime improve operational efficiency.
