中文摘要:为寻求对辊柱塞式成型机锯末制粒时的最优成型参数,探索成型参数对成型结果的影响规律,以锯末含水率、成型模具长径比和主轴转速为试验因素,以成型颗粒密度和成型机生产率为试验指标,基于Design-Expert BBD(Box-Behnken Design)试验设计方法对试验数据进行了处理和分析,建立了试验因素对试验指标的回归方程。结果表明:对辊柱塞式成型机采用锯末为原料制粒时,最优成型参数为:含水率15.5%、成型模具长径比5.3、主轴转速47.25r/min。在此条件下,成型颗粒密度和成型机生产率分别可达到1.17g/cm3 、75kg/h;各试验因素对成型颗粒密度的贡献率从大到小依次为:成型模具长径比、主轴转速、含水率,各试验因素对成型机生产率的贡献率从大到小依次为:含水率、成型模具长径比、主轴转速;成型颗粒密度试验值与预测值最大相对误差为0.426%,成型机生产率最大相对误差为2.733%,吻合程度较高。

Abstract:To seek for the optimal forming parameters of the roller briquetting machine with plungers and explore the influence law of the forming parameters on the forming results, sawdust was used as the raw material, the moisture content, the length to diameter ratio of the forming mold and the spindle speed were taken as the experimental factors, while the density of the forming particle and the productivity of the briquetting machine as the experimental indexes, the experimental data was processed and analyzed by the experiment design method of Design-Expert BBD (Box-Behnken Design), and the regression equations of the experimental factors on the experimental indexes were established. The results showed that the optimal results of the moisture content of sawdust, the length to diameter ratio of the forming mold and the spindle speed were 15.5%, 5.3, 47.25r/min,respectively. On this condition,the density of the forming particle and the productivity of the briquetting machine can reach 1.17g/cm3, 75kg/h, respectively. The contribution rate of the experimental factors on the forming particle density in the order from large to small: the length to diameter ratio of the forming mold, the spindle speed, the moisture content, while on the density of the forming particle: the moisture content, the length to diameter ratio of the forming mold, the spindle speed. The maximum relative error is 0.426% between the experimental value and the predicted value of the density of the forming particle,while it’s 2.733% on the productivity of the briquetting machine, so theres high consistency.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
