Vertical Ring Die for Wood Pellet Mill Alloy Steel Ring Die Mold Spare Parts

Vertical Ring Die for Wood Pellet Mill Alloy Steel Ring Die Mold Spare Parts

Premium alloy steel vertical ring die for LSH-700 wood pellet mills. Engineered with high-carbon alloy steel, customized compression ratios, and precision vacuum heat treatment to maximize service life and pellet production output. Ideal replacement wear parts for biomass pellet machines.

As the core wear component of a vertical wood pellet mill, the Vertical Ring Die directly determines the density, glossiness, and output efficiency of the final biomass pellets, as well as the overall operation cost of the pellet production line. 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.

1. Superior Material & Forging Quality

   We 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.

2. Precision CNC Drilling & Smooth Hole Finish

   Equipped 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.

3. Advanced Vacuum Heat Treatment

   Utilizing 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.

4. 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.

5. Double-Row / Reversible Design Flexibility

   Many 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.

Our 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. They perform exceptionally well with:

• Hardwood & Softwood Sawdust

• Wood Shavings & Timber Residues
