Why Do Identical Pellet Machines Have Different Output Capacities?
As biomass energy gains momentum, pellet machines are widely adopted for fuel production. However, users often face inconsistent outputs with the same model. Here’s why capacity varies and how to optimize performance.
1. Mold Running-In Process
New pellet machine molds require proper breaking-in:
- Grind with oil: Use oil-treated materials (e.g., sawdust mixed with 10-15% moisture) to smooth the ring-die’s surface.
- Adjust roller gap: Ensure the roller and die gap is optimized for even pressure distribution. Tighten bolts after adjustment.
- Monitor: A well-calibrated mold stabilizes output within 20-30 minutes of initial use.
2. Material Specifications: Size & Moisture
- Particle size: Raw material must be smaller than pellet diameter (e.g., ≤6-8mm for 8mm pellets).
- Moisture content: Maintain 10-15% moisture—excess causes clogging; too little reduces binding efficiency.
- Consistency is key: Inconsistent feedstock leads to erratic output.
3. Compression Ratio & Die Maintenance
- Match compression ratio: Each material (e.g., wood, straw) requires a specific die compression ratio. Test during machine commissioning.
- Avoid material swaps: Changing feedstock without adjusting the die ratio disrupts production.
- Replace aging dies: Worn dies cause irregular pellet discharge. For example, a Model 560 die lasts ~1,000 hours.
