1. Core Compression Components

These are high-wear parts essential for the actual pellet formation and extrusion process.

• Ring Die / Flat Die:
  • Premium alloy or stainless steel dies featuring customized compression ratios for different biomass raw materials (sawdust, rice husk, straw).
• Roller Assembly:
  • Complete heavy-duty roller units designed to withstand high pressure and ensure uniform material distribution.
• Roller Shells:
  • Available in dimpled, straight-grooved, or helical-grooved patterns to maximize grip and friction on specific biomass types.
• Roller Shaft / Eccentric Shaft:
  • High-tensile steel shafts that support the roller assembly and allow precise gap adjustment between the roller and the die.

2. Cutting & Discharge System

Parts responsible for sizing the finished pellets and clearing them out of the pellet chamber.

• Pellet Cutting Knives / Blades:
  • Adjustable, wear-resistant steel blades used to control the exact length of the extruded biomass pellets.
• Knife Holders:
  • Heavy-duty brackets that lock the cutting blades firmly into position.
• Deflector / Discharge Scraper:
  • Internal scrapers that sweep the hot, formed pellets out of the machine casing toward the discharge chute.

3. Power Transmission & Drive Train

Components that transfer power from the main motor to the pelletizing assembly.

• Main Shaft & Gearbox Gears:
  • Precision-ground helical or spur gears designed for low noise, low vibration, and maximum torque transfer.
• Drive V-Belts & Pulleys:
  • High-strength, anti-static belts and balanced pulleys for belt-driven pellet machines.
• Flexible Shaft Couplings:
  • Heavy-duty elastomeric or grid couplings used to connect the electric motor to the gearbox while dampening shock loads.

4. Bearings & Sealing Solutions

Critical parts needed to maintain smooth rotation and protect internal components from abrasive biomass dust.

• Main Shaft Bearings:
  • Premium double-row spherical roller bearings built to handle extreme axial and radial loads.
• Roller Bearings:
  • High-temperature cylindrical or tapered roller bearings packed inside the roller shells.
• High-Temperature Oil Seals:
  • Specialized fluororubber (Viton) seals designed to keep lubrication inside the gearbox and keep fine wood/husk dust out.
• O-Rings & Gaskets:
  • Custom-fit sealing kits to prevent oil leaks across the machine body.

5. Fasteners, Structural & Safety Components

Hardware required for machine assembly, calibrations, and safe operations.

• Die Clamp / Wear Rings:
  • Segmented or single-piece heavy rings that securely lock the ring die onto the driving rim.
• Shear Pins / Safety Pins:
  • Mechanical protection pins designed to snap instantly if an uncrushable object (like iron pieces) enters the machine, preventing catastrophic motor damage.
• Adjusting Bolts & Nuts:
  • High-grade thread fasteners utilized for precise roller-to-die gap calibrations.
