打印机的使用产生了大量废粉盒。它们包含铝、塑料、钢和碳粉。废旧碳粉盒如不妥善处理，将会污染环境。我们前期工作中已经建设了一条环保型废粉盒回收生产线。采用涡流分离技术将粉碎的废粉盒中的铝颗粒与塑料颗粒分离。但粉碎后的废粉盒中存在空心铝颗粒，与塑料颗粒的分离率较低。关于涡流分离中空心铝颗粒的信息很少。为了提高涡流分离效率，建立了涡流分离中空心铝颗粒的涡流力和运动行为模型。在空心铝颗粒与实心铝颗粒的水平投射比较中，我们发现空心字符大大降低了水平线......
Abundant waste toner cartridges have been generated from the use of printers. They contain aluminum, plastic, steel, and toner. Waste toner cartridges will pollute the environment if they are not properly treated. An environment-friendly recovery line of waste toner cartridges had been constructed in our previous work. Eddy current separation was employed to separate aluminum particles from plastic particles of crushed waste toner cartridges. However, hollow aluminum particles existed in crushed waste toner cartridges, and they have a rather low separation rate from plastic particles. There was little information about hollow aluminum particles in eddy current separation. For improvement of the efficiency of eddy current separation, models of eddy current force and movement behaviors of hollow aluminum particles in eddy current separation were established. In a comparison of horizontal throws of hollow aluminum particles to solid aluminum particles, we found hollow characters greatly decreased the horizon...
