一、概述六十年代末期,由于我国铁氧体永磁材料迅速发展,为研制和使用永磁磁选设备开辟了一条新途径。当时研制成的φ600×1500和φ750×1800等永磁圆筒磁选机,和原来使用的电磁带式磁选机比较:具有生产能力大,选别指标稳定,占地面积小,机身重量轻,耗电量少,操作维护简单等一系列优点。因此,到七十年代初,几乎全部用永磁圆筒磁选机取代了电磁带式磁
I. Overview In the late 1960s, due to the rapid development of ferrite magnet materials in our country, a new approach has been opened up for the development and use of permanent magnetic separator equipment. At that time developed into φ600 × 1500 and φ750 × 1800 and other permanent magnetic separator, and the original use of magnetic tape magnetic separator compared with the production capacity, the selection of indicators of stability, small footprint, body weight Light, low power consumption, easy operation and maintenance and a series of advantages. Therefore, by the early seventies, almost all of the permanent magnetic cylinder magnetic separator replaced the electromagnetic tape magnetic
