Engineering Case Study
A biomass energy company in Eastern Europe developed a pellet production plant using forestry residues as raw materials.

The plant installed two industrial wood pellet machines supplied by Shandong Changsheng Machinery, each equipped with a 560 mm ring die and a 160 kW motor.

The complete pellet production line included raw material crushing, drying, pelletizing, cooling, screening, and automatic packaging systems.

After commissioning, the plant achieved a stable pellet output of approximately 6 tons per hour. Pellet density and durability met international biomass fuel standards, and production waste was significantly reduced.

This project demonstrated the importance of proper equipment configuration and engineering design in biomass pellet production.
