How to choose an electromagnetic iron remover suitable for yourself?

一、正确选用电磁除铁器须同时考虑物料的含铁情况.除铁要求、使用环境和除铁器自身的特性 当物料用胶带输送机运送时，要把胶带机的因素考虑在内。

First, the correct selection of the electromagnetic iron remover should take into account the iron content of the material. In addition to the iron requirements, the use environment and the characteristics of the iron remover itself, when the material is conveyer with the belt conveyor, the factors of the belt conveyor should be taken into account.

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 contains more iron, the self discharging electromagnetic iron remover with continuous iron discharge capacity should be selected, and the self unloading electromagnetic iron remover can be used to protect the belt conveyer from the risk of 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. However, when the iron remover is used, when the iron rod is sucked up and sucked tightly, the other head, such as sticking to the conveyor belt, is prone to the longitudinal tearing of the tape.

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 using environmental dust (such as coal dust, smoke, 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 is arranged), the material has a front force and a loose shape, which is favorable for removing iron. The suspension height can be increased properly. However, the iron component in the 800mm direction except for the magnetic pole normal direction of the iron should be changed into non-magnetic material.

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 (i.e. cross layout), a non-magnetic linear roller can be installed under the adhesive tape to improve the effect of removing iron.

七、当胶带运输机的带速大于2.5m S时，通常除铁器应装在头部。如采用提高磁场强度的办法，并配以非磁性托辊，亦可装于中部，同样可取得良好的除铁效果。

Seven, when the belt conveyor speed is greater than 2.5m S, usually the iron should be installed on the head. If the magnetic field strength is improved and the non magnetic idler can be installed in the middle part, good iron removal effect can also be achieved.

八、一般情况下，除铁器的磁系结构为开式磁路，其吸铁有下列特点；吸大的长的易于小的短的；吸尖的易于球的；吸动的易于静的。因此，对除铁要求较高的场合，应适当提高除铁器的规格或采用两级、三级除铁。

Eight. In general, the magnetic structure of the iron device is an open magnetic circuit, and its iron absorption has the following characteristics; it is easy to absorb the long and short short; sucks the tip of the ball easily; the suction is easy to be static. Therefore, in the case of high iron removal requirements, the specifications of iron remover should be appropriately increased or iron removal at two or three stages should be adopted.

九、采用多级除铁器时.后级的除铁能力应高于前级的除铁能力，即后级除铁器在胶带表面的磁场力（CH）应大于前级胶带表面的磁场力(CH2)。.否则，后级除铁器除铁效果很差。

Nine. When the multistage iron remover is used, the iron removal capacity of the rear stage should be higher than that of the former grade, that is, the magnetic field force (CH) of the rear iron separator on the surface of the tape should be larger than the magnetic field force (CH2) on the surface of the front grade tape. Otherwise, the effect of iron removal in the post stage is very poor.

十、当物料含铁少时，采用金属探测器配合电磁除铁器(选用短时工作制)联合使用，可获得更好效果。

Ten. When the material contains less iron, the combination of metal detector and electromagnetic iron remover (short time working system) can achieve better results.

十一、短时工作制的除铁器的吸力，通常比长期工作制除铁器的吸力更大，能耗及机械磨损更小，价格亦更低。国内新一代的金属探测器已问世。因此，这种除铁方式值得推广。

Eleven. The suction of the iron remover in short working hours is usually larger than that of the long-term working system, and the energy consumption and mechanical wear are smaller and the price is lower. A new generation of metal detectors in China have come out. Therefore, this method of iron removal is worth popularizing.

十二、磁性物料的除铁己有多种方式，因情况较为复杂，宜与制造厂合作，共同研究，才能取得满意结果。

Twelve, there are various ways to remove iron from magnetic materials. Due to the complexity of the situation, it is advisable to cooperate with manufacturers to study together to achieve satisfactory results.
