The is a device that recycles wood chips, corn stover, wood shavings, bark and waste materials from lumber mills. After being processed into pellet fuel for combustion by this production line, Zhang Sheng biomass pellet machine effectively solves the shortcomings of difficult pelletizing and poor effect of crude fiber of straw and other materials. The formed pellet fuel has the characteristics of high burning value, high density, green environmental protection and convenient transportation. The volume of the pellets after molding is 1/8 of the volume of the raw material, the density is 0.8-1.5, and the calorific value can reach 3400~6000 kcal. Biomass pellet machine is a new type of bioenergy equipment, it effectively treats various waste materials and is a good choice for turning waste into treasure.
