This paper presents an integrated processing technology for the recycling of spent Zn-Mn dry batteries by means of dry-wet method, which combines mechanical decortications and vacuum technique. On the basis of analyzing current research and applications, the characteristics and problems of existing technologies in this field are discussed. Research achievements such as its processing, key techniques and equipment for mechanical decortications are introduced in detail. This technology has many advantages, including higher recovery rate, lower energy consumption, minimum secondary pollution and lower cost for equipment, which is suitable for the purpose of recycling spent batteries in small and medium-sized cities and provides a new option for technicians and researchers in related fields.
