近年来国外把铁铠螺线管磁系作为一种先进的磁系结构应用于大型湿式强磁选设备中(图1),国内也正在加紧研制。本文将分析该磁系的几个主要方面,力求加深对它的认识,以利研制。本文谈论的对象,仅限于选矿中要用到的磁极板面积较大(大于1×1米~2)、磁极距较小(不到20厘米)、背景场强不高(几千奥斯特)的情况。一、所需磁势的估算(一)方法及说明由于铁铠螺线管磁系的磁场处于上下两块铁制平行平板之间,
In recent years, foreign Tieyao solenoid magnet system as an advanced magnetic structure used in large-scale wet magnetic separator equipment (Figure 1), the domestic is also stepping up its research and development. This article will analyze several major aspects of the magnet system, and strive to deepen its understanding, to facilitate the development. The subject of this paper is limited to the larger plate area (greater than 1 × 1 m ~ 2), the smaller magnetic pole pitch (less than 20 cm) and the low background field strength (tens of Austere )Case. First, the required magnetic potential estimation (A) methods and instructions Because the magnetic field of the iron armor solenoid system in the upper and lower two parallel between the iron plate,
