摘  要：
针对模辊式成型机在生产生物质颗粒燃料过程中存在能耗高等问题,以玉米秸秆为原料,研究成型机模辊间隙、主轴转速和模孔直径等参数对生产率、吨燃料能耗、颗粒燃料的成型率、机械耐久性和颗粒密度等的影响。结果表明:模辊间隙仅对成型率有影响,间隙为0.2 mm最优。吨燃料能耗和颗粒密度随主轴转速增大而减小;模孔直径大,生产率高,吨燃料能耗低,颗粒密度小;为保证生产率,主轴转速应大于等于160 r/min。不同因素试验,颗粒燃料的成型率大于95%,机械耐久性大于96%,均符合生物质颗粒燃料要求。

摘  要：
Experiment on the main parameter of biomass pellet mill with corn straw was performed on account of high energy consuming in the process of modeling.Energy consumption per ton solid biofuel,the rate of qualified molded biofuel,mechanical durability and particle density were used to evaluate the effect of changing clearances between rolls and die,spindle speed and diameter of die orifice.The results indicated that clearances between rolls and die justhad an effect on the rate of qualified molded biofuel,and the best optimal value was 0.2mm,the energy consumption and particle density reducing by increasing of the spindle speed,bigger diameter of die orifice would bring about higher productivity and lower energy consumption.The spindle speed scope should not lower than 160r/min to ensure the high productivity.Further,the rate of qualified molded biofuel was bigger than 95% and mechanical durability was bigger than 96%,which matched the requirements when experiments were done with different factors.
