Biomass solidification molding technology is an important way to utilize biomass energy, the core parts of the molding machine is mainly composed of mold holes and push rod. Due to the complex and changeable forces in the die hole working process,three typical die holes,circle,square and equilateral triangle, were selected for modeling force analysis,the extrusion pressures of these three die holes types were derived by theoretical analysis,the conclusion of extrusion pressures formula were analyzed. It was concluded that the different shape of mold holes might affect the molding of biomass pa...
