High-Grade 20CrMnTi Alloy Steel ConstructionForged 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).Frequently Asked Questions (FAQ)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.

Our high-performance LSH-700 vertical ring die mold spare parts are specifically designed and manufactured to withstand extreme pressure, high temperatures, and severe mechanical abrasion encountered during hardwood, softwood, and agricultural residue pelletizing processes.Crafted from top-grade forged alloy steel (20CrMnTi, 42CrMo) or premium stainless steel, each ring die undergoes advanced CNC gun-drilling and automatic countersinking processes. This guarantees mirror-smooth inner hole finishes, preventing material clogging, lowering power consumption, and ensuring rapid, uniform pellet extrusion from the very first run.Key Features & Technical AdvantagesSuperior Material & Forging QualityWe use high-purity forged alloy steel blanks with dense internal structure and zero porosity. Compared to ordinary cast materials, our forged ring dies offer significantly higher tensile strength and fatigue resistance under high-impact conditions.Precision CNC Drilling & Smooth Hole FinishEquipped with multi-spindle CNC gun-drilling machines, all die holes are precision-drilled with exact tolerance. The high-polish inner surface minimizes friction between raw materials and hole walls, ensuring smooth discharge, high compression efficiency, and reduced power consumption per ton of pellets.Advanced Vacuum Heat TreatmentUtilizing state-of-the-art vacuum heat treatment furnaces and carburizing technology, our ring dies achieve a balanced hardness profile:Surface Hardness: HRC 58–62 for maximum wear resistance.Core Toughness: High impact ductility to prevent cracking or fracturing during heavy-duty operations.Customized Compression Ratios (L/D Ratio)Different raw materials (pine, oak, eucalyptus, sawdust, rice husk, bagasse, or agricultural waste) require precise compression ratios. We provide custom-tailored hole diameters (3mm to 12mm) and effective compression lengths to optimize your specific pelletizing process.Double-Row / Reversible Design FlexibilityMany of our vertical ring die models feature a symmetrical double-row hole design. Once one side experiences wear, the die can be turned over for continued operation, effectively doubling its service life and reducing spare parts maintenance costs.Applications & SuitabilityOur alloy steel vertical ring die spare parts are widely used in commercial biomass pellet plants, wood processing facilities, forestry waste recycling units, and biofuel energy manufacturing plants.
