e一tuonju fenxuan磁团聚分选(magnetie agglomeration sepa-ration)细粒强磁性矿物在低弱磁场中受磁力和剪切力作用，选择性地形成磁团聚体与脉石分离的磁选方法。所用低弱磁场的磁感应强度为5一25mT，比通常预磁磁感应强度50mT和弱磁场磁选机磁感应强度loomT低得多。磁场和剪切力场的作用仅产生磁团聚，团聚体在磁场和重力场综合作用下沉降速度加大，从而提高了与非团聚的脉石的分离效果。磁团聚分选法分选精度高，用于磁铁矿的精选时，能获得超级精矿。 磁团聚分选设备由磁系和切向给水装置或搅拌装置构成(见图)。磁系由内外两组同心筒形磁极组成，可以降低磁场不均匀性。磁极由铁氧体永磁块构成，磁系吸_ -一{，‘ 磁团聚分选设备示意图 l一提升杆;2一给矿箱门一给矿管;4一溢流槽; 5一内磁系.6一外磁系刃一进水管邝一精矿阀沿轴向是断续的，使强磁性矿石在沉降过程中处于团聚一分散一团聚的动态过程，有利于选择性团聚和排除脉石，提高精矿品位及分选效率。沿切向给入上升水流，是为了产生剪切力，加强水力清洗作用。有些设备安有搅拌叶轮，其作用与切向水流相同。根据磁力和流体剪切力的比值及两种力的方向，来控制强磁性矿粒的团聚和分散状态，达到磁团聚的高度选择性。在分选区保持矿浆的适当浓度，以形成床层和发生干涉沉降作用。(参见彩图插页第12页) 〔落多l润、
