Why Choose Hongyue 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 High Chrome Alloy, 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
Is this matrix suitable for 8mm industrial wood pellets? ▼
Yes, this matrix is gun-drilled with 8mm holes and a custom compression ratio tailored for industrial sawdust and biomass pellet production.
Does this fit the Andritz Sprout PM30? ▼
Absolutely. Our replacement matrix is manufactured to accurately match the mounting dimensions of both Andritz LM26 and PM30 equipment.
Why Material Matters
The lifespan of a ring die is determined by its material composition and heat treatment. We use only certified X46Cr13 stainless steel and 20CrMnTi alloy steel, processed through vacuum heat treatment to ensure uniform hardness and maximum wear resistance.
