ISO 9001-Certified Jufeng Paper Grinding Disc Manufacturing Factory Special Report

1. Introduction  

- Function: The Refiner Disc is a critical component in papermaking machinery, utilizing mechanical action (shearing, crushing, stretching) to process pulp fibers, ensuring optimal fiber characteristics for paper quality.  

- Key Feature: Over 100 customizable tooth profiles tailored to different pulps, refining stages, and production requirements.  

2. Types

 -Stainless Steel Welding Grinding Disc: Manufactured by welding process.  

- Milling Discs: Precision-machined for specific applications.  

- Compatibility: Compatible with major brands (Valmet, Andritz, Voith) and diverse machinery models.  

3. Applications

- Used in:  

  - Double Disc Refiners (pulp lines).  

  - High Consistency Refiners.  

  - Defibrators (MDF production).  

  - Heat Dispersers and Deflakers.  

4. Raw Materials 

-Material Type ,Hardness, Properties         

-wear-resistant stainless steel ,  48 - 52HRC 

-Customized for specific needs

5. Key Advantages

- Durability: High wear resistance, impact toughness, and extended service life.  

- Quality Assurance:  

- Pre-shipment tests (hardness, destructive, dynamic/static balance).  

- Strict tolerances (diameter/thickness error <1mm).  

- Customization: Diverse tooth patterns for varied pulp types and refining stages.  

- Packaging:Clearly labeled with specifications and certifications.  

6. Installation & Usage Guidelines

- Bolts: Avoid reusing old bolts; ensure uniform tightening to prevent imbalance.
