"SHANGHENGDAmachinery manufacturing co., LTD". is one of the first Chinese companies to initiate its own research capabilities in biomass pellet technology. Due to a lack of experience in biomass pelletization, most Chinese companies are completely dependant on outdated technology derived from machinery designed to produce grain feed. Disadvantages of these machines include high speeds of
rotation, low output, low pellet density, high mechanical losses, and high manufacturing costs. Some of these problems persist within the industry in China to the present day.
