摘　　要：介绍了振动式旧砂再生机的基本结构,以及旧砂再生过程的能量传递规律。讨论了现有的几种振动再生机的结构与性能特点,以及借鉴振动磨原理提高旧砂再生效果的方法,并介绍了离散元法(DEM)引入到旧砂再生研究中的可能。The basic structure of vibration type used sand reclaimer, and the energy transmission behavior of used sand reclamation were introduced. The structure and characteristic of existing vibration type reclaimers were discussed, as well as the improvement methods of used sand reclamation were introduced by the theory of vibration mill. It is possible that the discrete element method （DEM） can be introduced to research on used sand reclamation.
