Permanent magnetic separator for coal port, large thermal power plant, coal mine, mine, building materials and other special requirements on the removal of iron high places, can work normally in the dust, moisture, sea salt spray corrosion and other harsh environment, oil cooling is the most commonly used electromagnetic separator cooling, manufactured by production the evaporative cooling process of iron, can effectively prevent the leakage of oil, the product quality is stable, mature and reliable.

除铁器根据其使用场合、环境、除铁要求等均有所不同可分为好多种除铁方式。 除铁器励磁方式有电磁、永磁二大类。其弃铁方式也形式多样。有些设计院、用户等由于对除铁器性能及使用场合了解不够，选型时容易出现不合理的问题，生产厂家往往偏重磁性能，也忽略弃铁方式，因而会影响使用效果。只有充沛了解除铁要求、使用场所及环境条件才干选择最佳匹配，充分发挥除铁器性能，达到理想的除铁效果。

In addition to the use of iron in accordance with the occasion, environment, iron and other requirements are different, can be divided into a variety of iron removal methods. There are two kinds of excitation modes: electromagnetic and permanent magnet. The way iron is discarded is also diverse. Some design institutes, users because of the separator performance and applications do not know enough, unreasonable problems in the selection, manufacturers tend to focus on magnetic properties, also ignore discard iron way, so the effect will be. Only fully understand the requirements of iron removal, the use of the site and environmental conditions, in order to select the best match, give full play to the performance of iron remover, to achieve the desired effect of iron removal.

人工卸铁式人工卸铁式一般见于盘式除铁器，包括方盘、圆盘式电磁与永磁除铁器。就地弃铁式一般情况下，永磁盘式(板式)除铁器采用人工就地弃铁方式，这种方式优点是结构最简单，占地面积最少，上方也无需电动小车，投资最少。但由于需人工用手将铁件从除铁器外表拿开，较费力，此种方式只适用于除去小件铁器，如有大块铁件，人工难以去除。

Manual unloading iron type manual unloading iron type commonly found in disc separator, including square plate, disc type electromagnetic and permanent magnetic separators. In situ abandoned iron in general conditions, permanent magnet (plate) separator using artificial local discard iron way, this way has the advantages of simple structure, covers an area of at least above, no electric car, at least investment. But it is more difficult to remove the iron pieces from the outside of the iron by hand. This method is only suitable for removing small pieces of iron, such as large pieces of iron, which are difficult to remove by hand.

一般情况下，物料中含有铁磁性物质单件质量不大于1kg情况下，并且在输送带宽度不大于1000mm时才会选用。有些情况下，由于受场地限制，一些电磁盘式除铁器也采用就地弃铁方式，电磁除铁器在经过数小时的工作后，先停止输送机的运转，然后电磁除铁器停止励磁，数秒钟后，铁件自行掉落在下方输送带上，由人工将其拣除工将其拣除。

Under normal circumstances, the material contains ferromagnetic material, single mass is not greater than 1kg, and the width of the conveyor belt is not greater than 1000mm will be used. In some cases, due to space limitations, some electromagnetic separators used in disc discard iron way, electromagnetic separator after several hours of work after the first stop operation of the conveyor, and then stop the excitation of electromagnetic separator, after a few seconds, iron pieces automatically fall below the conveyor belt, by the artificial picking with the exception of the pick among.

6、控制部分可以皮带机连锁，可实现就地手动控制和集中控制两种方式。

6, the control part can be belt conveyor chain, can be achieved in situ manual control and centralized control in two ways.

7、无励磁线圈，省电节能。

7 、 no excitation coil, save electricity and save energy.

8、不存在绝缘和耐压问题。配上防爆电机驱动的弃铁输送带即可成为防爆除尘器。但是，永磁除铁器的磁场强度会发生衰减，选用时应注意调查落实

8, there is no insulation and pressure problems. An iron free conveyer belt, which is driven by an explosion-proof motor, can be used as an explosion-proof dust collector. However, the magnetic field strength of permanent magnet iron remover will be attenuated, and the investigation should be carried out when selecting

选择除铁器应根据杂换除净率要求、物料含铁情况、现场工作环境等正确选用除铁器。

The selection of iron removing tools shall be based on the requirements of the impurity removal rate, the iron content of the material and the working environment on the spot.

对杂铁除净率要求较高时，也可采用不同工作方式的除铁设备配合使用，如皮带机头部采用永磁滚筒，皮带机中部选用带式除铁器。

When the rate of iron removal is higher, the iron removing equipment with different working ways can be used in conjunction, such as the permanent magnetic roller used in the head of the belt conveyor, and the belt type iron separator in the middle of the belt conveyor.

料层较厚、物料粒度较大时，宜选用超强磁除铁器；或大一级或大二级超型号选用普通除铁器；也可多级除铁；多级除铁应尽可能选用铁器安装在皮带机头部使用。

The material layer is thicker, larger particle size, should use super magnetic separators; or a secondary level or super models use ordinary separators; also can be multi iron removal; multistage iron removal should be used iron installed in the belt conveyor head as far as possible.

现场环境粉尘较严重时，应选用全封闭结构的除铁器.

When the field dust is serious, a totally enclosed structure of iron remover should be used

When power capacity is insufficient, permanent magnet iron remover should be used

物料中含杂铁较多时，应选用自卸式除铁器。

When there is much iron in the material, the self discharging iron remover shall be used.

除铁器安装在皮带机头部时，因物料有惯性力，离开皮带时处于松散状态，利于除铁，如果将皮带机头部的驱动改为非磁性材料制作，除铁效果会更好.

When the iron is installed on the head of the belt conveyor, the material is in a loose state because of the inertia force of the material. When it is left the belt, it is good for removing iron. If the drive of the belt machine head is changed into non-magnetic material, the effect of iron removal will be better

皮带机带宽1400mm以下推荐选用带式永磁除铁器，皮带机带宽1600mm以上推荐选用电磁除铁器。

Belt conveyor bandwidth 1400mm below, it is recommended to use belt type permanent magnet separator, belt conveyor bandwidth 1600mm above, recommend the use of electromagnetic iron remover.

采用多级除铁时，后级的除铁吸力应高于前级的除铁吸力，否则，会除低除铁效果。.

When multistage iron removal is used, the iron suction in the rear stage should be higher than the iron suction in the front stage, otherwise it will eliminate the iron removal effect. .

现场环境特殊、情况复杂时，我们将为用户进行特殊设计，以满足实际工况要求。

When the environment is special and the situation is complex, we will design special designs for the users to meet the actual working conditions.

除铁器的吊挂装置应按着现场工作环境的实际需要来选定，按除铁器的吊挂位置、环境条件测定后选购。

The hanging device of the iron remover shall be selected according to the actual working conditions of the field, and shall be purchased after the hanging position of the iron remover and the environmental conditions are determined.

皮带机中部安装除铁器除铁时，可将除铁器下方的托辊改为无磁平托辊，这样就能进一步提高除失效果。

Belt conveyor is arranged at the middle part of Deferrizater iron, can be in addition to the iron roller under no magnetic Pinto roller, a way to further increase the removal effect of loss.
