A demonstration at a commercial wood pelleting plant in the United States shows that LignoBond® 870L increased production rate, reduced power consumption and improved pellet durability.
LignoBond 870L performance at a wood pelleting plant
Key takeaways:
- Production rate increased by 21%
- Amperage reduced; power consumption reduced from 101 kWh/ton to 81 kWh/ton
- Pellet durability (PDI) increased from 96.5 to 96.9
Press amperage: 1 of 2 motors
Monitoring of production began at 09:30. Feeder-screw speed was at 38-Hz, kWh/Ton was 99.9 and pellet durability was 96.4. LignoBond 870L was first applied at 09:56 at a rate of 0.73% liquid on fibre. There was an immediate drop in amperage from 167 to 139, kWh/Tons dropped to 83.3 and pellet durability increased to 97.2. Water addition was stopped at 10:06 with very little change. At 10:22, production rate was increased by 21% (46-Hz), which reduced the dosage of LignoBond 870L to 0.60%. Pellet durability reduced slightly to 96.9 and kWh/Ton dropped to 80.8. LignoBond 870L feed was shut off at 10:37. Amperage increased to 173, kWh/Ton increased to 103.4 and pellet durability was lowered to 96.5.
