Energy shortage and environmental pollution is a common serious problem restricting the development of world economy and the society. Biomass energy has become the fourth major energy resource after oil, coal, natural gas energy for the good properties of green, clean, and renewable. So it is important to research biomass energy technology to solve the energy crisis and environmental protection. The technology of biomass densification is a simple solution to make the biomass resource become low cost and high value. In this paper, a new kind of biomass pellet molding mechanism had been deeply studied, and the pellet molding machine, Q450, was designed by the CAD/CAE, Solidworks. The load conditions of three molding assemblies fixed inside the enclosure bodies had also been studied and analysed on the designed machine. Then a method, named FEA (Finite Element Analysis), was conducted to research the mechanical properties of enclosure assembly for the pellet machine in Simulation. Through analysis, the results were obtained that the maximum stress and displacement of enclosure bodies were separately 31.37Mpa and 7.583e-2mm, which could provide the reliable strength and stiffness to the enclosure assembly. It convincingly ensured that Q450 pellet molding machine had enough reliability and security.
