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
- Casting Discs: Manufactured via casting processes.
- 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
Alloy ,62 HRC (High wear resistance)
Cast Iron (Chrome-Coated) High chromium, durable
17-4PH Stainless Steel , 37–42 HRC (Precipitation-hardened)
Medium Carbon S.S. , 52–55 HRC
High Carbon S.S.,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.
- Handling: Use care during transport; clean installation surfaces.
- Operation:
- Avoid running without gaps.
- Remove debris from slurry to prevent damage.
- Halt operation if automatic controls fail.
- Installation Order:
- Follow numbered sequence (clockwise) for balance.
- Do not mix disc groups (thickness variations between groups).
