First, the correct selection of electromagnetic iron remover must consider the iron content of the material at the same time. In addition to the requirements of iron, the environment of use and the characteristics of the iron remover, the factors of belt conveyor should be taken into consideration when the material is transported by belt conveyor.  

二、当物料中含铁较多时，应选用连续排铁能力的自卸式电磁除铁器，选用自卸式电磁除铁器可有效保护胶带输送机免遭纵向撕裂之虞。

Two, when the iron content is relatively large, the self discharging electromagnetic iron remover with continuous iron removal capacity should be selected. The self unloading electromagnetic iron remover can effectively protect the belt conveyor from longitudinal tear.

三、当物料中含铁较少时。宜选用人工除铁式电磁除铁器。可适当降低悬挂高度，有利于出铁。但采用人工除铁的除铁器，当铁杆一头吸起并被紧紧吸住时，另一头如顶住输送胶带则容易发生胶带纵向撕裂事故。

Three. When there is less iron in the material. It is advisable to choose an iron removal iron remover with artificial iron removal. It can properly reduce the height of the suspension, which is beneficial to the iron production. But the artificial Deferrizater iron, when the iron head sucked up and is firmly suck, another head as against the conveyor belt is prone to accident belt longitudinal tearing.

四、当使用环境粉尘(如煤尘、烟尘、泥尘、灰尘等)较严重时。应选用全封闭结构的除铁器。

Four, when the use of environmental dust (such as coal dust, dust, dust, dust, etc.) is more serious. Iron remover with fully enclosed structure should be selected.

五、电磁除铁器安装在中部(即同线布置)时，因物料有前冲力和处于松散状有利于除铁。悬挂高度可适当增加。但除铁器磁极法线方向800mm内的铁质构件应改为非磁性材料。

Five. When the electromagnetic iron remover is installed in the middle (that is, the same line arrangement), the material has the front force and the loose shape is beneficial to the iron removal. The suspension height can be increased properly. However, the iron components in the direction of 800mm in the direction of the magnetic pole of the irons should be changed to nonmagnetic materials.

六、电磁除铁器安装在中部(即交叉布置)时，为提高除铁效果，可在胶带下增装一非磁性直线托辊。

Six. When the electromagnetic iron remover is installed in the middle (that is, cross layout), in order to improve the effect of iron removal, a nonmagnetic straight line roller can be installed under the tape.
