A biomass pellet mill is a device that converts biomass raw materials into pellet fuel, playing a crucial role in the field of biomass energy utilization.
The working principle of a biomass pellet mill: Biomass pellet mills primarily operate through mechanical extrusion. Raw materials are conveyed into the pelleting chamber, where rotating rollers and a die apply pressure, compressing the material into pellets within the die's orifices. During this process, the lignin in the raw material softens under high temperature and pressure, acting as a natural binder. The resulting pellets are extruded from the die orifices and cut into appropriate lengths.
