本发明中，废液经滚筒外壳12的进液管进入，其中的水、磨料和铁屑以相等的速度打在通电的电磁滚筒13内壁，其中水和磨料由于不具有磁性，故只有部分铁屑吸附在电磁滚筒内壁，完成铁屑初筛，未被吸附的铁屑和水、磨料一起落到左电磁滤网7上，此时铁屑被再次吸附，完成铁屑细分，而磨料和水通过左电磁滤网7落到右磨料筛18上，此时水可以通过滤网而磨料留在滤网上，此时完成磨料分离。当经过一段时间后，当电磁滚筒13内壁和左电磁滤网7、右磨料筛18上的铁屑和磨料达到一定质量后，控制阀10关闭，电磁滚筒13断电，使得其吸附的铁屑完全落在左电磁滤网7上，这时第一转动电机5带动第一转动盘6旋转180度，使左电磁滤网7位于铁 屑收集桶8上方，此时电磁滤网7断电，第一转动盘6带动电磁滤网7翻转，将铁屑抖落到铁屑收集桶8内，完成铁屑收集。在第一转动电机5运动的同时，旋转电机16带动第二转动盘15在水平方向旋转180度，使得左右磨料筛位置互换，此时第二转动盘15带动右磨料筛18翻转，使得磨料落入磨料收集桶20中。本发明通过电磁原理吸附铁屑，通过电磁滚筒的初筛和电磁滤网的细分，有效去除了钢轨打磨废液中的铁屑，避免了铁屑通过循环***进入高压泵导致的管路故障。

步骤二，对铁屑初筛完毕后，对左电磁滤网7通电，将磨料废液按照指定流速输送至左电磁滤网7上，所述左电磁滤网7用于对经由电磁滚筒模块出料口流出的磨料废液中的铁屑进行吸附，并过滤废液和磨料。具体的，电磁滚筒13继续通电，同时，滚筒电机11停止工作，对左电磁滤网7通电(如果右电磁滤网9放置于电磁滚筒13下方，则对电磁滚筒13进行通电)，将电磁滚筒13中的磨料废液按照指定的流速排出至左电磁滤网7上，左电磁滤网7用于对经由电磁滚筒模块出料口流出的磨料废液中的铁屑进行吸附，同时左电磁滤网7上设置有过滤孔，以过滤废液和磨料，未被电磁滚筒13吸附的铁屑再次被左电磁滤网7吸附。
步骤三，待电磁滚筒模块中磨料废液流尽后，给所述电磁滚筒模块断电，使得电磁滚筒模块吸附的铁屑掉落在并吸附左电磁滤网7上，然后在第一转动连杆模块的驱动下与右电磁滤网9交换位置，所述左电磁滤网7断电， 以将收集的铁屑放入至所述铁屑收集桶8中。
