Abstract
The developing history and current research status of biomass compressive shaping technology was described in this thesis and all kinds of equipment for biomass formation were also compared. On the basis of analysis on forces exerted on flat die and rollers, main technical parameters of flat die pellet mill were calculated by applying simplified force model, Through the design of the power to determine the motor selection, For the rolling device design calculation to determine the power of the motor, the design of forming die and the design of transmission system,spindle check,selection of key and intensity,etc,On this basis,the design for the production of straw briquette, press block of flat die straw briquette machine.
Keywords: biomass compression molding model die pelletizer
