Biomass pelletizing technology can densify loose biomass, significantly improve the performance of biomass products as an effective way to use biomass energy. However, the short life of the key part—biomass loop-die becomes the constraint of the biomass pelletizing development, so it is significant to study the biomass pelletizing technology and the fatigue life of the loop-die.

生物质固体成型技术使松散的生物质致密化,能显著提高生物质制品的性能,成为规模化利用生物质能源的一种有效途径,但是生物质固体成型机理的不完善和成型机械的使用寿命短,尤其是关键零部件——环模使用寿命短,成为制约生物质固体成型技术发展的瓶颈,开展生物质固体成型机理和环模寿命研究对开辟生物质新能源的利用具有十分重要的意义。
