近年来,随着矿山工业的高度发展,特别是对微粒体管理技术的要求日益严格。作为粉体粒度管理的装置,也是属于最精密性的筛分,从筛子精度的要求和筛孔微细化的要求,需要利用精密筛分。所谓精密筛分就是通称的微细筛,它是用电铸法作的筛孔 In recent years, with the high development of the mining industry, the requirements for microsomal management technology have become increasingly stringent. As a device for controlling the particle size of powder, it is also the most accurate screening. From the requirements of sieve accuracy and the miniaturization of the sieve, precise sieving is required. The so-called precision sieve is commonly known as the fine sieve, which is made by electroforming the sieve
