Why Choose Tianyou Spare Parts?
Precision manufacturing for ultimate pelleting performance.
Bearing Steel Forging
High-quality bearing steel forging eliminates internal defects and ensures uniform metallurgical structure for consistent performance under heavy loads.
Precision Corrugation
CNC-machined corrugated surface pattern provides optimal material grip and feeding efficiency for consistent pellet quality.
Surface Hardening
Advanced case-hardening process achieves HRC 58-62 surface hardness while maintaining tough core for impact resistance.

Premium Material & Extended Lifespan
Forged from high-grade 20CrMnTi (Alloy Steel), our replacement ring dies and roller shells offer superior resistance against corrosion and abrasive wear during high-temperature pelleting. Processed through advanced vacuum heat treatment, we ensure a uniform hardness (typically HRC 52-56), which maximizes output capacity while minimizing the cost per ton of feed produced.
Frequently Asked Questions
What is the expected lifespan? ▼
