The results show that the fluidization characteristics of scrap printed circuit board particles depend on the average size and type of particles. The scrap printed circuit boards particles, belonging to Geldart A group with strong viscous force, whose fluidization was similar to fluidization of Geldart C, was difficult to fluidize. Whereas, the scrap printed circuit board particles belonging to Geldart B can be fluidized smoothly.

实验结果表明，电路板塑料颗粒为Geldart A类颗粒时，粘性力大，塌落特性明显，流化性能较差，具有拟C类颗粒的流化特性；电路板塑料颗粒为B类颗粒时，塌落特征不明显，并且随着粒径的增大，最小流化速度也增大。
