按永磁磁选机的材料可分为干式除铁器与湿式除铁器。
According to the material of the permanent magnetic separator, it can be divided into dry iron remover and wet iron remover.
干式永磁除铁器一般分为带式和筒式
Dry permanent magnet separators are generally divided into belt and tube type
带式永磁除铁器其特点是自动卸铁，磁场恒定，无冷热态变化，故障少，在l200mm 带宽以下应用较普遍，由于目前磁屏蔽技术发展还不过关，所以给制、运输、安装、操作、维修均带来不少麻烦，如大块铁被吸上磁箱存在着既有可能甩不掉从而夹死皮带烧毁电机的问题，同时又难以清除，并有可能对磁块造成损坏，因而在大规格的应用上受到一定的限制。 它主要由一个多极固定磁系和一个由非导磁材料制成的圆筒构成。固定磁系的包角为180°或者360°，圆筒围绕该磁系转动或者整个磁滚筒转动。一般可用来代替带式永磁磁选机主动轮，既可带动皮带送物料，同时又起到分选的作用，在钢厂钢渣回收用、矿山铁砂。
Belt type permanent magnetic separator is characterized by automatic unloading iron, constant magnetic field and no cold change, less failure, in the following l200mm bandwidth is commonly used, due to the current development of magnetic shielding technology does not pass, so to the system, transportation, installation, operation and maintenance are a lot of trouble, such as magnetic iron box is large there can be sucked off and clamping belt burning motor problems, at the same time, it is difficult to remove, and may cause damage to the magnet, which limits the application in high specification. It is mainly composed of a multipole fixed magnetic system and a cylinder made of non-magnetic material. The package angle of the fixed magnetic system is 180 degrees or 360 degrees, the cylinder rotates around the magnetic system or the whole magnetic cylinder rotates. Can be used instead of belt type permanent magnetic separator driving wheel can drive the belt material, also play a role in sorting, recycling, steel slag iron ore mine.
永磁湿式磁选机的选机结构有以下特点：首先永磁湿式磁选机结构由6个主要部分组成，分别是圆筒、辊筒、刷辊、磁系、槽体和传动。
The structure of the permanent magnetic wet magnetic separator has the following characteristics: first, the structure of permanent magnetic wet magnetic separator consists of 6 main parts, namely, cylinder, roller, brush roller, magnetic system, groove and drive.
特点：
