Parameter Study Of Biomass Pellet Making Machine With Rolling Mechanism In Natural Condition

Biomass energy sources is becoming important source of energy for human beings in the present life, is located in the three traditional energy sources of oil, coal and natural gas, the world’s fourth largest energy. Biomass briquetting technology working in natural condition is one of the important technologies of the biomass energy. This paper for the first time have done a parametric study of the biomass briquetting on a roller plunger molding machine in natural condition through exploratory experimental study and computer simulation analysis, optimized design of the main processing parameters of the molding machine.The thesis is based on forestry nonprofit industry-specific "woody shrub resources to promote the industrialization of sandy wasteland restoration technology " and on the basis of the results of "948" introduction project,"High density biomass briquette shaping technology introduction ".Do the experiments on biomass of small wood chips in a straight forming hole, and then do the assisted analysis using finite element software ANSYS, and data analysis software MATLAB, analyze the friction of this material in straight forming hole between the cylinder wall. Obtained in different molding diameter forming tube length design parameters, and derive the empirical equation. With Pro/Engineer software modeling capabilities and institutional analysis module, combined with internal meshing gear engagement theory, institutional analysis of the design parameters of the molding machine molding components in order to get the best design parameters of the forming roller and forming pressure roller.This study, provides a theoretical and experimental basis for biomass briquetting on a roller plunger molding machine in natural condition design, structural improvements and processing parameters optimization.
