用户在选用除铁器时，必须先考虑的是输送胶带的带宽、带速、倾角，物料的性质、湿度、粒度、厚度，物料中的含铁量的多少、铁磁物的粒度、性质，除铁要求、使用环境（温度、湿度、粉尘、有无腐蚀性等）、除铁器本身的特性，安装的位置、空间等。

When selecting the iron remover, the user must first consider the bandwidth of the conveyer belt, the speed of the belt, the dip angle, the nature of the material, the humidity, the granularity, the thickness, the iron content in the material, the size and nature of the ferromagnetic material, the iron removal requirements, the use environment (temperature, humidity, dust, corrosion, etc.), and the iron remover itself The characteristics, location, space, etc. of the installation.

当物料中含铁量较多时，应选用连续自动除铁的自卸式电磁除铁器（如市场上的RCDC、RCDD、RCDF系列），自卸式永磁除铁器（如RCYC、RCYD系列），永磁滚筒（如RCT系列），电磁滚筒（如CFDL系列）。

When there are more iron content in the material, the self discharging electromagnetic iron remover with continuous automatic iron removal (such as the RCDC, RCDD, RCDF Series in the market), the self discharging permanent magnet iron remover (such as RCYC, RCYD Series), the permanent magnetic roller (such as RCT Series), and the electromagnetic roller (such as CFDL Series) should be selected.

当物料中含铁量较少时，应选用永磁除铁器（如市场上的RCYB系列），电磁除铁器（如RCDA、RCDB、RCDE、CF系列）。

When the iron content in the material is small, permanent magnet separator (such as RCYB series on the market) and electromagnetic iron remover (such as RCDA, RCDB, RCDE, CF Series) should be selected.

当物料中的铁磁物特别少时，选用金属探测仪和强磁自卸式电、永磁除铁器配套使用，达到自动监测自动除铁，具有省电节能、寿命长、除铁效果好等特点。

When the ferromagnetic materials in the material are very small, the metal detector and the strong magnetic dump electric and permanent magnet iron remover are used to automatically monitor the iron removal. It has the characteristics of saving energy, long life and good effect of iron removal.

当使用悬挂式电、永磁除铁器时，如物料过厚可与无磁托辊配套使用，提高除净率，也可适当降低悬挂高度，以达到理想的除铁效果。

When the suspended electric and permanent magnet iron remover is used, if the material is too thick to be used with the non magnetic roller, the removal rate can be improved and the height of the suspension can be reduced to achieve the ideal effect of iron removal.

当使用环境（如粉尘、烟尘、灰尘）较严重时，应选用全密封结构的电磁除铁器、永磁除铁器。

When the use of environment (such as dust, smoke, dust) is more serious, we should choose a fully sealed electromagnetic iron remover and permanent magnet iron remover.

当物料中含有除铁器不能吸附的非磁性金属材料时，应选用金属探测仪检测出金属物，自动停机报警后人工除铁。

When the materials contain non-magnetic metal materials that can not be adsorbed by irons, metal detectors should be used to detect metal objects and automatically shut down after the alarm and remove iron manually.

当用户不使用输送胶带而采用溜槽、管道、链板机、提升机等设备输送物料时，应采用管道式永磁除铁器。

When users do not use conveyor belt and use chute, pipe, chain planter, hoist and other equipment to transport materials, pipe type permanent magnet iron remover should be adopted.

对于除铁要求较高的场合，如要求悬挂高度大于额定悬挂高度，或物料厚度大于额定厚度时，应选用大于本规格的除铁器或采用多级除铁。

For high requirements for iron removal, if the suspension height is higher than the rated suspension height, or the material thickness is greater than the rated thickness, the iron remover larger than this specification or the multistage iron removal should be selected.
