Pellet Mill Roller Accessories

Product Introduction

This pellet mill roller is specially designed for various ring die and flat die pellet mills, focusing on three core needs: wear resistance, high efficiency and stability. Selected high-quality alloy and cast iron materials, combined with precision structural design and professional heat treatment technology, it is suitable for processing various raw materials such as sawdust, palm kernel shell, straw and organic fertilizer, greatly improving pellet forming efficiency and equipment service life, and is a key upgraded component for industrial granulation production lines.

Core Advantages

• Top-Tier Material · Super Wear Resistance——Selected high-quality base materials such as GCR15 bearing steel and 20CrMn alloy steel, processed by carburizing heat treatment and quenching low-temperature tempering, the hardness reaches HRC60-65, the wear resistance is 3 times higher than that of ordinary carbon steel rollers, the service life is up to 800-1500 hours, easily handling wear challenges of various raw materials.

• Precision Pattern · Wide Adaptability——The surface adopts honeycomb, scallop and corrugated multi-pattern design. Honeycomb pattern ensures uniform wear of ring die, scallop pattern prevents side slipping of aquatic feed, corrugated pattern enhances traction of biomass raw materials; precision eccentric shaft design supports free adjustment of roller-ring die gap, compatible with 350-1250 type pellet mills, direct installation without modification.

• High Efficiency & Energy Saving · Output Improvement——Uniform arrangement and optimized mechanical structure ensure stable operation without vibration, greatly increasing the effective pressing area, pellet forming rate exceeds 95%, and equipment energy consumption is reduced by 15-20%; tapered roller design reduces resistance and prevents material slipping, output is 20% higher than ordinary rollers, significantly reducing unit production cost.

• Modular Design · Easy Installation & Maintenance——Compact and lightweight structure, modular design does not require professional tools, one person can complete replacement in 15 minutes; equipped with automatic lubrication interface, regular lubrication can maintain optimal performance and reduce maintenance frequency; accessories are in stock all year round, key wearing parts can be pre-stocked to effectively shorten downtime.

• Corrosion & Impact Resistance · Harsh Condition Adaptation——High chromium cast iron and cemented carbide materials have excellent corrosion resistance, suitable for processing impurity-containing or corrosive raw materials such as organic fertilizer and chemical materials; alloy steel material combines strength and toughness, can withstand impact loads of frequent start-stop, supporting 24-hour continuous high-intensity production.

Product Details & Craftsmanship

• Material Processing Technology

Raw materials are strictly tested and screened for composition, and vacuum smelting technology is used to remove impurities to ensure material purity; precision processing by CNC lathes, with dimensional tolerance controlled within ±0.02mm to ensure perfect fit with pellet mills; surface carburizing heat treatment, uniform hardened layer depth (2-3mm), consistent hardness distribution, avoiding excessive local wear; finally, ultrasonic flaw detection and dynamic balance testing are performed to ensure no internal cracks and operational jitter.

• Key Details Display

① Roller surface pattern: Processed by precision milling technology, pattern depth 1.5-3mm, enhancing material grabbing force; ② Bearing mounting position: High-frequency quenching treatment, hardness HRC58-60, extending bearing service life; ③ Sealing structure: Double oil seal design, preventing dust from entering the interior, protecting bearings and eccentric shafts; ④ Connection interface: Standardized thread design, compatible with mainstream pellet mill brand interfaces, strong versatility.

• Quality Inspection Standards

Each batch of rollers undergoes triple quality inspection: ① Material composition testing (spectral analyzer): Ensuring materials meet standards; ② Dimensional accuracy testing (coordinate measuring machine): Verifying key dimensional tolerances; ③ Performance testing (simulated working condition testing machine): Continuous operation for 24 hours at 80℃ high temperature and 20MPa pressure, testing wear amount and stability, and only leaving the factory after passing.
