| 永磁除铁器适用于输煤港口、大型火电厂、煤矿、矿山、建材等对除铁要求特别高的场所，可在粉尘、潮湿、海边盐雾腐蚀严重等恶劣环境下正常工作，油冷已是国际上最常用 的电磁除铁器冷却方式，该产品按照德国和美国同类产品标准设计，采用蒸发冷却铁器生产工艺制造，可有效防油渗漏，产品质量稳定、成熟、可靠。仔细分析各个应用领域，都处于快速发展阶段，可见现在永磁除铁器在各个行业都处于旺季，可见永磁除铁器发展趋势一片大好。 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 method, the design of the product according to the German and American Standard of similar products, manufacturing production process using evaporative cooling iron, can effectively prevent the leakage of oil, the product quality is stable, mature and reliable. Careful analysis of the various application areas, are in rapid development stage, it can be seen that now permanent magnet iron remover in various industries are in the peak season, it can be seen that the development trend of permanent magnet iron remover is good. 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。 The iron removal tools can be divided into many kinds of iron removal methods according to their use occasions, environment and iron removal requirements. There are two kinds of excitation modes of iron remover: electromagnetic and permanent magnet. The way of scrap iron is also diversified. 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 by fully understanding the requirements of iron removal, the use of sites and environmental conditions, can we choose the best match, and 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. However, it is more difficult to remove the iron parts from the outside of the iron remover by hand. This method is only suitable for removing small iron pieces. If there are large pieces of iron, it is difficult to remove them. 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。我公司生产的除铁器除铁效率高，一般不会出现这种情况。 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 selected. 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. Our company produces iron removal efficiency is high, generally does not appear this case. 1、不需要整流控制装置，可靠性高。 1, no rectifier control device, high reliability. 2、高性能钕铁硼做磁源，磁性强，不易退磁。 3、两边滚筒为腰鼓形结构，具备自动纠偏功能，密封性极好，所以能很好的适应各种恶劣环境。、 4、不存在温升问题，磁场强度也就不存在“冷态”“热态”之分，磁场恒定。 2. High performance NdFeB magnetic source, strong magnetism, not easy to demagnetization. 3, both sides of roller for the drum structure, with automatic correction function, excellent sealing, so it can well adapt to the harsh environment. And 4, there is no temperature rise problem, the magnetic field strength also does not exist "cold" "hot", the magnetic field constant. 5、断电时，吸在除铁器上的铁件不会掉回到输送物料上。 5. When the power is off, the iron parts which are sucked on the iron remover will not fall back to the conveying material. 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。 7、无励磁线圈，省电节能。 6, the control part can be belt conveyor chain, can be achieved in situ manual control and centralized control of two ways. 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. Explosion proof dust remover can be realized by the iron scrap conveyer belt which is driven by explosion proof motor. However, the magnetic field strength of permanent magnet iron separator 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。那么更多选择条件都有哪些呢？下面我们就为大家介绍一下。 Iron remover should be selected according to the requirements of impurity removal rate, iron content in the material and working environment on the spot. So what are the more selective conditions? Let's introduce it to you. 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 iron removal rate is high, the iron removal equipment with different working modes can also be used. For example, the belt conveyor head adopts permanent magnetic drum, and the belt type separator is used in the middle part 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 dust is serious in the field, a totally enclosed structure of iron remover should be chosen 电力容量不足时，应选用永磁除铁器. When power capacity is insufficient, permanent magnet iron remover should be selected 物料中含杂铁较多时，应选用自卸式除铁器。 When the impurity iron in the material is more, the self unloading iron remover should be selected. 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, because the material has inertia force, it is in loose state when leaving the belt, which is good for removing iron. If the driver of the belt conveyor 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 type belt width below 1400mm is recommended to use belt type permanent magnet separator, belt conveyor bandwidth more than 1600mm is recommended to use electromagnetic separator. 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 removal suction of the rear stage should be higher than that of the former 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 make special design 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 should be selected according to the actual working environment of the site, and should be selected according to the hanging position of the iron remover and the environmental conditions. 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. |
