Refiner filling wear directly impacts pulp quality consistency and maintenance downtime. Rapid bar edge rounding in steep-taper refiners leads to wider gaps, higher power draw, and unrefined stock passing through the system.
Metallurgical Performance Comparison:
| Feature | Standard Cast Iron / Steel | HUATAO High-Chromium Alloy |
| Surface Hardness | 40 – 45 HRC | 52 – 56 HRC |
| Bar Edge Retention | Moderate (prone to rounding) | Superior (sharp edge profile throughout life) |
| Corrosion Resistance | Low | High (resistant to recycled pulp chemicals) |
| Replacement Cycle | 6 – 8 Months | 10 – 14 Months |
By upgrading to HUATAO Claflin 101 fillings, mills achieve longer run times, fewer scheduled turnarounds, and lower annual cost per ton of pulp.
HUATAO supplies OEM conical refiner plates for pulp and paper mills, offering customized materials, refining patterns and wear resistance for reliable pulp refining performance.
