Until now, the direction which made the raw material of base material was found by separating the magnetic powder, after plastic prepaid card and highway card of the hard paper are crushed.In this study, it continued, subway ticket JR ticket and JR credit card in which base material was a hard paper were used to be a sample, the separation of magnetic powder layer and paper fiber bed was tried.(1) On the subway ticket, the paper fiber bed was able to be separated from other layer after the agitation grinding by screening and magnetic separation in the underwater.(2) The paper fiber was separated from the magnetic powder layer, while JR ticket and JR credit card stir in underwater, after it smashes by the hammer mill flocculent, and magnetic powder was removed in the bar magnet.(3) It was proven that the quantity of the water in the underwater agitation was over 100 times on the condition for obtaining the better separation efficiency on these samples.There was large significance on grinding system and separation method used by this experiment in the point that the environment was not fouled.

迄今为止，通过对塑料预付卡和高速公路卡的硬纸进行粉碎后，分离出磁性粉末，找到了制作基材的方向，本研究继续以硬纸为基材的地铁票、JR车票和JR信用卡为样本，尝试磁性粉末层与纸纤维层的分离。(1)在地铁票上，纸纤维层经过水下搅拌研磨，通过筛分和磁选，可以与其他层分离。(2)将纸纤维与磁粉层分离，同时将JR车票和JR信用卡在水下搅拌，经锤片式粉碎机絮凝后，在磁棒中去除磁粉。(3)实验证明，在获得较好分离效果的条件下，水下搅拌的水量在100倍以上，在不污染环境的前提下，本实验所采用的研磨系统和分离方法具有重要意义。
