LSH-560 Pellet Mill Roller Assembly | 20CrMnTi Wear-Resistant Roller Shell & Shaft
The LSH-560 Pellet Mill Roller Assembly is a vital, heavy-duty replacement spare part designed specifically for 560-type vertical and horizontal ring die pellet machines. Engineered for demanding biomass pelletizing environments, this complete roller assembly features a high-grade 20CrMnTi alloy steel structure, precision spline shaft, and deep straight-groove roller shell.
Whether processing hardwood saw dust, softwood shavings, crop straw, or rice husks, the LSH-560 roller assembly provides superior grip, minimizes slippage, and delivers maximum pressing force for consistent, high-density pellet production.

Forged from premium 20CrMnTi alloy steel, this roller assembly undergoes advanced carburizing heat treatment to achieve an extreme surface hardness of 58–62 HRC. This process ensures high surface wear resistance while retaining a tough core to absorb heavy operational shocks without cracking or breaking.
2. Optimized Straight-Groove Anti-Slip DesignThe outer roller shell features precision-machined straight grooves that firmly grip raw materials (sawdust, wood chips, agricultural residue). This non-slip traction prevents material buildup, enhances compression efficiency into the ring die holes, and significantly raises hourly output.
3. Precision Heavy-Duty Splined ShaftEquipped with a standard precision splined shaft end, the assembly delivers uniform torque distribution under high load conditions. It eliminates rotation slippage, reduces vibration, and guarantees stable mechanical alignment during high-speed pressing.
4. Dust-Proof & Long-Lasting Structural SealDesigned with heavy-duty side retaining plates and dust-tight seals, the assembly effectively prevents fine biomass dust and abrasive grit from penetrating internal bearings. This prolongs grease life, extends bearing maintenance cycles, and lowers overall operational downtime.
Applications & Raw Material CompatibilityCompatible Equipment: 560 Series Vertical / Horizontal Ring Die Wood Pellet Presses, Biomass Granulators, Feed Mills.
Suitable Raw Materials: Pine, Beech, Oak, Mixed Sawdust, Wood Shavings, Bamboo Powder, Straw, Rice Husk, Peanut Shells, and EFB (Empty Fruit Bunches).
Q1: How often should the LSH-560 pellet mill roller assembly be replaced?
A: Service life depends on material abrasiveness and operating hours. Thanks to the 58–62 HRC hardness of 20CrMnTi steel, our rollers typically offer extended service life compared to standard carbon steel alternatives under normal biomass pelletizing conditions.
Q2: Does this assembly come fully built and ready for installation?
A: Yes, the LSH-560 roller assembly comes complete with the splined shaft, roller shell, end covers, and internal locking components for fast and easy direct replacement.
