Energy and its affinitive problems has become a perennial hot spot in the world. Comparedwith fossil fuels such as coal, oil and natural gas, biomass energy has become more and moreimportant in the global energy structure for its renewability and environmental protection.Therefore, wood-pellet as one the biomass energy with high quality has a broad prospect andapplication value.As an important step of wood pellet production, the pulverizing effect and energyconsumption directly affect the quality of wood-pellet and its producing energy consumption.Therefore, research in raw material pulverizer of Wood pellet with high performance and lowenergy consumption has important theoretical significance and practical value. This paperdesigned a new kind of raw material of Wood pellet pulverizer. The main research and work areas follows:(1) The processing of crushing, force application and disruptive performance are analyzed.Theoretical research is also taken based on the research of wood performance and issued theimpact crushing as the main crushing performance of wood-pellet raw material.(2) The dynamics principle and impact factors are analyzed under different impactcondition based on the impact crushing theory. The design of new wood-pellet raw materialpulverizer is proposed. Calculation of its structural and processing parameters is done accordingto theory and experience.(3) Virtual Assembly and Parameterization Design of wood-pellet raw material pulverizerare performed by Pro/e software. Simulation and Interference Detection for virtual assembly arealso done to verify its correctness and Reliability(4) The modal analysis of main spindle is also carried out by using ANSYS12.0Workbench to verify that the strength of the main spindle meets the operation requirements andthe design is reliable.(5) Orthogonal test consisting of three factors the number of hammer, screen aperture andhammer sieve spacing at three different levels is carried out. Then come to this conclusion: theinfluence of the number of hammer is the most significant, and secondly is screen aperture, thelast is hammer sieve spacing.
