1. Wood Waste Processing Line Introduction

2. Full Workflow of Wood Waste Pellet Line with Hammer Mill

1. Raw Material FeedingChain plate feeder transports large wood scraps, logs and pallets uniformly to primary shredder. Blockage and overload protection ensure stable continuous feeding.
2. Primary Coarse ShreddingBig wood blocks are cut into 2–5cm wood chips via wood shredder, lowering feeding pressure for the follow-up hammer mill.
3. Fine Crushing by Wood Hammer Mill (Core Section)Pre-shredded wood chips enter industrial hammer mill. High-speed alloy hammers strike materials to produce uniform sawdust of 3–10 mm. Replaceable screen mesh adjusts finished particle size to match pellet mill requirements.Built-in dust removal system controls flying sawdust; wear-resistant hammer pieces extend service life for long-shift operation.
4. Sawdust DryingWet sawdust from hammer mill usually contains 30–50% moisture. Rotary dryer reduces moisture to 12–18%, the ideal range for pellet molding.
5. Pellet MoldingQualified dry sawdust is sent to ring die pellet mill, extruded into solid cylindrical fuel pellets under high temperature and pressure.
6. Cooling & ScreeningHot soft pellets pass through counter-flow cooler to reduce temperature and hardness. Screener removes powder and unqualified broken pellets for reprocessing via hammer mill.
7. Finished Product Storage & PackingQualified wood pellets are stored in silos, then automatically packed into ton bags or small retail bags for delivery.

3. Core Function of Hammer Mill in Pellet Manufacturing Line

1. Standardize Raw Material Particle SizePellet machines cannot process oversized wood chunks. The hammer mill breaks materials into consistent fine sawdust to guarantee smooth extrusion and high pellet forming rate.
2. Improve Drying EfficiencyFine sawdust has larger contact area with hot air in dryers, cutting drying time and lowering fuel consumption of the whole line.
3. Reduce Wear Loss of Pellet Mill DieUniform small particles avoid uneven friction inside the ring die, greatly extending die service life and lowering spare part replacement costs.
4. Flexible Compatibility of Raw MaterialsOne industrial wood hammer mill handles mixed wood waste: pallets, branches, bark, waste furniture and wood offcuts. Factories can collect multiple waste materials to cut raw material costs.

4. Matching Hammer Mill Capacity for Different Pellet Lines

• Small pellet plant (0.5–1t/h finished pellets): 2–5t/h wood hammer mill
• Medium biomass factory (2–5t/h pellets): 8–15t/h heavy-duty hammer mill
• Large industrial pellet line (8–15t/h pellets): Double rotor large output hammer mill with double feeding ports

5. Supporting Auxiliary Equipment Matching Hammer Mill

• Magnetic separator: Remove iron nails, screws from waste pallets before hammer mill to protect hammers and screen from damage
• Pulse dust collector: Collect sawdust dust generated during hammer milling, meet EU environmental emission standards
• Conveyor belts & screw conveyors: Automatic closed material transportation to save labor cost
• Cyclone separator: Separate light impurities mixed in sawdust after hammer mill

6. Investment & Business Advantages of Complete Wood Waste Line

1. Low Raw Material CostWood waste is industrial and agricultural residual waste with low purchasing price; many factories accept free waste wood delivery.
2. High Market DemandWood pellets are widely used for household heating, boiler fuel, power plants and animal bedding, with stable export demand to Europe, Southeast Asia and North America.
3. Short Payback PeriodThe matched hammer mill ensures high line operation rate and low maintenance cost. Most medium-sized pellet factories recover investment within 1–2 years.
4. Environment-Friendly Circular EconomyRecycling wood waste into biomass fuel reduces landfill waste and replaces fossil fuels, complying with global carbon neutrality policies.

7. Wood Waste Processing Line Common FAQ

1. Can one hammer mill process both dry and wet wood waste?Standard hammer mills fit materials below 25% moisture. Super wet wood needs pre-drying before crushing.
2. How often to replace hammer mill wear parts?Alloy hammers work 800–1200 working hours under normal wood waste processing conditions.
3. Is CE certification available for the whole wood processing line?All hammer mills and complete pellet production lines support CE, ISO export certification for overseas recycling and biomass factories.
4. Can we expand line capacity later by upgrading hammer mill?The production line reserves installation space. Customers can replace higher-output hammer mills without rebuilding the whole layout.
