Why Choose Tianyou Spare Parts?
Precision manufacturing for ultimate pelleting performance.
Bearing Steel Forging
High-quality bearing steel forging eliminates internal defects for consistent performance.
Precision Assembly
Each assembly is balanced and tested to ensure smooth operation at high speeds.
Sealed Bearing System
Premium sealed bearings protect against dust contamination and reduce maintenance.
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 included in the roller assembly? ▼
The complete assembly includes roller shell, shaft, bearings, seals, and eccentric adjustment mechanism. Ready for immediate installation.
How do I adjust roller gap on CPM pellet mills? ▼
Use the eccentric adjustment mechanism to set proper gap between roller and die. Typical gap is 0.1-0.3mm for optimal pelleting.
Frequently Bought Together
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.
