永磁除鐵器的磁源采用高性能鍶鐵氧體硬磁材料，它產(chǎn)生的磁場強度高，磁場深度大，使用年限長，磁極組均布在工作面組成平面磁系，當永磁選鐵器懸掛在皮帶運輸機一端，（見安裝示意圖）物料與鐵雜物順皮帶運輸機轉(zhuǎn)動將同時沖向永磁選鐵器，這樣磁性物料(鐵雜物)就牢固吸附在永磁選器上，而非磁性物料就掉落在所需的工作位置上，從而達到了選鐵的目的。永磁選鐵器主要使用于各種皮帶運輸機，懸掛在落料端從而達到選鐵目的，用于水泥行業(yè)、化工工業(yè)用煤、小型礦山、建筑材料、木材加工、鑄造型砂處理以及其它物料中的除鐵，并能夠保證下道工序順利進行。The structure is illustrated below.The magnetic source of thepermanent magnetic separator is made of high-performance strontiumiron oxidation hard magnetic materials.It produces high magneticfield intensity,large depth magnetic field with durability.Magneticfields are planted in groups on its working surface and form a flatmagnetic system .When the separator hanging over the end of therubber belt conveyer(see the installation illustration),thematerial moves with belt conveyer to the separator and the ironimpurties will be absorbed on the separator,while the non-magneticmaterial drops to the designed working position,thus the separationaccomplished.
