By using smaller mesh screen in the high speed hammer mill, the adhesion between magnetic parts and non-magnetic parts of the cards and the highway tickets were better separated. The results are summarized.(1) By separation with 2,500 Gauss magnet in dry process, from prepaid card pulverized with 4mm×7mm screen, non-magnetic group with 99.8 wt% or more plastic content ratio could be recovered.(2) Re-pulverizing can raise the non-magnetic recovery percentage. Also separation before re-pulverization rises up the pulverizing efficiency of the hammer mill. But it should be taken into consideration that re-pulverization also increases the loss percentage of the samples.(3) To use the recovered plastic as raw materials, further study concerning the recovered plastic properties is necessary.(4) On the highway tickets, the separation with the 8,500 Gauss magnet has failed to remove all the magnetic parts but through this experiment, it's leaned that the magnetic parts can be removed by wet separation process. Thus, using stronger magnet may provide a better separation effect for the highway ticket samples.(5) Pulverization with smaller mesh screen may be efficient for separation but it may weaken the recycled paper.

在高速锤片式粉碎机中采用较小的筛网，可以较好地分离卡片磁性部分和非磁性部分与公路票证的粘附。结果进行了总结。(1)用2,500高斯磁铁干法分选，从4 mm × 7 mm筛粉的预付卡中回收非磁性基团，其含塑率可达99.8wt%以上。(2)二次粉碎可提高非磁性回收率。此外，在再粉碎之前的分离提高了锤式粉碎机的粉碎效率。但应考虑到再粉碎也会增加样品的损失率。(3)为了利用回收塑料作为原材料，有必要对回收塑料的性能进行进一步的研究。(4)在高速公路车票上，用8,500高斯磁铁分选，未能将磁性部分全部去除，但通过本实验，得知可以采用湿法分选工艺去除磁性部分。因此，使用更强的磁体可以为高速公路票据样品提供更好的分离效果。(5)用较小的筛网粉碎可能对分离有效，但它可能会削弱再生纸。
