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。
Taking eucalyptus processing residue as the research object, the raw material compression molding experiment was carried out on the Longmen hydraulic press YM-10T. The radial compression experiment was carried out on the INSTRON 5564 universal material testing machine to analyze the effect of the forming parameters on the particle quality (particle relaxation density, And water impermeability). Taking into account the energy consumption, output and operating conditions of equipment related to the actual production process, the raw material for eucalyptus processing residues is in the range of 1 to 2 mm in particle size, 5 to 6 kN in molding pressure, 10 to 15% in moisture of raw materials and 90 to 120 ° C in forming temperature , Dwell time 6 ~ 9 s suitable for the production of pellet fuel.
