2.连续作业式高梯度磁选机为高岭土提纯而制造的螺线管高梯度磁选机是一种作业周期率〔(有效工作时间/整个周期时间)×100％]为70～80％的周期作业式磁选设备,它只适用来分离磁性物含量低(通常低于2％)的微细粒物料。若用于磁性物含量较高的矿石(如氧化铁燧岩含赤铁矿50％以上),那么不到一分钟就会把钢毛介质全部饱和,这 2. Continuous operation of high-gradient magnetic separator for the manufacture of kaolin purification solenoid high gradient magnetic separator is a kind of operating cycle rate 〔(effective working hours / the entire cycle time) × 100%] is 70 to 80% of the Periodic magnetic separation equipment, it is only suitable for the separation of magnetic materials with low (usually less than 2%) of the fine-grained material. If used for ores with high magnetic content (eg, taconite containing hematite more than 50%), the medium will be completely saturated in less than a minute
