国内选净最新技术——干式选净理论和实践初探

Latest Foreign purification Technology Teseatch of Dry Purification Theory and Its Practice

选净与选别不同，选净主要要求物料颗粒表面的洁净。本文旨在探索干式选净设备的设计、制造的理论和实践问题。尽管设计已在实践中获得成功，理论依据已得到工业试验的印证，但是由于干式选净技术目前在国内尚属新技术，还有待于进一步开展研究工作。

Cleaning out is to clear the particle surface of the bulk material,which is different from separation.The theoretical and practical problems of designing and manufacturing dry cleaning out equipment have been investigated.The design has been put in use successfully and the theory has been proofed in industrial application.However,dry cleaning out is a new technology presently in this country and should be studied further in future.
