Why Choose Tianyou Spare Parts?
Precision manufacturing for ultimate pelleting performance.

Deep Carburization
Advanced carburizing heat treatment achieves HRC 58-62 surface hardness while maintaining a tough inner core, providing extreme wear resistance against abrasive wood fibers.

CNC Gun Drilling
Precision gun-drilled holes with controlled geometry ensure consistent pellet density and maximum throughput for hardwood and softwood biomass pelleting.

Reinforced Blank Forging
High-pressure forged blanks eliminate internal metallurgical defects, preventing catastrophic die failure during high-pressure biomass compression.
Premium Material & Extended Lifespan
Forged from high-grade X46Cr13 (Stainless 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
Can this stainless steel die handle wood pellet production? ▼
Yes, X46Cr13 stainless steel is specifically chosen for biomass applications due to its superior corrosion resistance against wood resin and acetic acid.
Is this die compatible with CPM 7722-7? ▼
Absolutely. Our dies are reverse-engineered to match both CPM 7722-6 and 7722-7 specifications with precision clamp mounting.
Precision. Hardness. Lifespan.
The Ring Die is the core of any pellet mill. A poor quality die means blocked holes, high energy consumption, and frequent downtime. Tianyou Machinery delivers OEM-quality replacement parts that match the exact specifications of major European and Chinese brands, but at a 30-50% lower cost.
