使用過程中除鐵機(jī)磁場強(qiáng)度變?nèi)?。除鐵機(jī)出現(xiàn)這種問題可能的誘因有溫度過高;陽光暴曬;酸堿腐蝕。具體可以用高斯計測量除鐵機(jī)的磁場強(qiáng)度。工作過程中除鐵機(jī)電機(jī)過熱及其聲響不正常。 此類除鐵機(jī)電機(jī)過熱及其聲響的異常問題可能是由于軸承潤滑不良或是磨損嚴(yán)重導(dǎo)致，或者是風(fēng)扇葉脫落或磨損引發(fā)，也可以考慮是否是開關(guān)線路接觸不良，或斷線跑單相引起，另外電壓過低也能造成類似問題，具體是哪種原因?qū)е拢瑧?yīng)根據(jù)除鐵機(jī)現(xiàn)場情況具體分析而定。減速機(jī)過熱。減速機(jī)過熱可能的原因有減速機(jī)齒輪油油量不足或油質(zhì)不良;除鐵機(jī)減速機(jī)齒輪與蝸桿過度磨損，或是嚙合不好;另外第三個原因可能是軸承潤滑不良或磨損嚴(yán)重致使除鐵機(jī)的減速機(jī)發(fā)熱過大。也有部分用戶反映，除鐵機(jī)在運轉(zhuǎn)中發(fā)現(xiàn)聲音不正常，圓筒被障礙物卡住，甚至使圓筒不能轉(zhuǎn)動，底箱顫動。 出現(xiàn)這種情況往往是被底箱的物體卡住，再就是磁塊脫落，使筒體嘎嘎作響，嚴(yán)重時會使筒皮劃破。這時應(yīng)停車檢修，排除故障。除鐵機(jī)的磁系采用優(yōu)質(zhì)鐵氧體材料或與稀土磁鋼復(fù)合而成，以前筒表平均磁感應(yīng)強(qiáng)度為100-600mT。目前由于技術(shù)的發(fā)展，除鐵機(jī)可以做成輥狀，磁場強(qiáng)度也提高到1644.3T.已經(jīng)是目前實測高的磁場強(qiáng)度。除鐵機(jī)可以分選的礦物很多比如磁鐵礦，褐鐵礦，赤鐵礦，錳菱鐵礦，鈦鐵礦，黑鎢礦，錳礦，碳酸錳礦，冶金錳礦，氧化錳礦，鐵砂礦，高嶺土，稀土礦等都可以用除鐵機(jī)來選別。磁選過程是在除鐵機(jī)的磁場中，借助磁力與機(jī)械力對礦粒的作用而實現(xiàn)分選的。不同的磁性的礦粒沿著不同的軌跡運動，從而分選為兩種或幾種單獨的選礦產(chǎn)品。順流式除鐵機(jī)處理能力大，適宜于處理較粗粒度的強(qiáng)磁性物料的粗選和精選，亦可多臺串連工作。順流式除鐵機(jī)當(dāng)給礦量大時，磁性礦粒容易損失于尾礦，因此要加強(qiáng)操作管理，控制較低的礦漿水平。 逆流式除鐵機(jī)適宜于細(xì)粒強(qiáng)磁性礦物的粗選與掃選作業(yè)，回收率較高，但精礦品位較低。因為粗粒物料易沉積堵塞選別空間，所以逆流型除鐵機(jī)不適于處理粗粒物料。半逆流除鐵機(jī)可以獲得高質(zhì)量的鐵精礦，同時也能得到較好的回收率，所以半逆流除鐵機(jī)在生產(chǎn)實踐中得到廣泛的應(yīng)用。

In the course of using, the magnetic field intensity of the iron removing machine is weak. In addition to the problem of iron removal machine may cause the temperature is too high; sun exposure; acid corrosion. The magnetic field strength of the iron removal machine can be measured by Gauss meter. In the course of the work, except for the overheating and abnormal sound of the motor. This kind of abnormal iron removing machine motor overheating and noise may be due to poor lubrication bearing or lead to serious wear, or fan off or wear caused, can also consider whether the switch line is bad, or break running caused by single-phase voltage is too low, also can cause similar problems, the concrete is a kind of cause. According to the iron removing machine site specific analysis and. Reducer overheating. The reason may have overheated reducer reducer gear oil shortage or oily bad; in addition to iron gear reducer and the worm meshing or excessive wear, is not good; the other third may be due to poor lubrication or bearing wear due to fever reducer except iron machine is too large. There are also some users reflect, in addition to the iron machine in the operation found that the sound is not normal, the cylinder is stuck in the obstruction, and even the cylinder can not rotate, the bottom of the box fibrillation. This is often the case by the bottom of the box to get stuck, and then the magnetic block off, so that the cylinder rattle, seriously when the cylinder will be cut. At this time should stop repair, troubleshooting. In addition, the magnetic system of iron removal machine is made of high quality ferrite material or rare earth magnetic steel, and the average magnetic induction intensity is 100-600mT. At present, due to the development of technology, in addition to the iron can be made into a roller shape, the magnetic field strength is also increased to 1644.3T. has been measured at high magnetic field strength. Iron removing machine can be a lot of sorting minerals such as magnetite, limonite, hematite, manganese siderite, ilmenite and wolframite, manganese ore, manganese ore, metallurgical manganese ore, manganese oxide, iron ore, kaolin, rare earth ore can be used to separate iron removing machine. In the magnetic field of the iron removal machine, the magnetic separation process is realized by means of magnetic force and mechanical force. Different magnetic particles move along different trajectories, which can be sorted into two or several separate mineral processing products. The utility model has the advantages of large processing capacity of the parallel flow type iron removing machine, and the utility model is suitable for the roughing and the selection of the strong magnetic materials with coarse grains. When the ore feeder is large, the magnetic ore particles are easy to be lost in the tailings, so the operation management should be strengthened to control the lower pulp level. The counter current type iron removing machine is suitable for coarse and strong magnetic minerals, and the recovery rate is high, but the concentrate grade is low. Because the coarse material is easy to deposit and separate the sorting space, the counter current type iron removing machine is not suitable for processing coarse materials. Semi countercurrent iron removal machine can obtain high quality iron concentrate, but also can get good recovery rate, so the semi countercurrent iron removal machine is widely used in production practice.
