摘　　要：本文阐述了首次采用附壁效应原理成功地对稀土抛光粉进行了多产品分级 ,它克服了传统离心式分级的诸多缺陷 ,使微粉分级的精度和效率提高到了新的水平 ,值得我国同行密切关注和推广应用。In this paper,we have been successful in gaining many products by using the Coanda effect. It abandons many typitical centifugal classifier shortcomings, makes fine classification precision and efficieny to our operation to bring new levels,and be good for the craft brothers in our country if it be osculatorily paid attention to and spreaded and used.
