成型参数对桉树加工剩余物成型颗粒品质影响的实验研究

EXPERIMENTAL RESEARCH OF EFFECT OF MOLDING PARAMETERS ON QUALITY OF EUCALYPTUS RESIDUE PELLETS

以桉树加工剩余物为研究对象,在龙门液压机YM-10T上进行原料压缩成型实验,在INSTRON5564型万能材料试验机上进行颗粒径向压缩实验,分析成型参数对颗粒品质(颗粒松弛密度、抗变形性和抗渗水性)的影响。考虑实际生产过程相关设备能耗、产量及运行状况,针对桉树加工剩余物原料,粒径范围1~2 mm、成型压力5~6 kN、原料水分10%~15%、成型温度90~120℃、保压时间6~9 s适合于颗粒燃料的生产。

Using eucalyptus residue as raw material, compression molding experiment was conducted in YM-10T longmen hydraulic press and pellet radial compression experiment was conducted in INSTRON5564 universal material testing machine to analyze the effect of molding parameters on pellet quality （density, deformation resistance and water permeability resistance）. Considering the energy consumption, yield and operating condition of actual production process, the suitable pellet production condition is 1-2 mm particle size, 5-6 kN molding pressure, 10%- 15% materialmoisture, 90-120 ℃ molding temperature and 6-9 s holding time.
