Application status and development requirements of electromagnetic iron remover in ceramic industry
1, building sanitary ceramics production enterprises pay more and more attention to the problem of iron, many enterprises have put it on the agenda, the main leaders personally involved or in charge of the leadership directly grasp. The use of iron remover is expanding, from the original glaze iron removal development to billet iron removal. The product that needs to remove iron is more and more, included daily use pottery, sanitary clean to provide and tile of wall and floor of all kinds of shallow white glaze, polishing brick. In addition to iron requirements are also more and more high, a production line from the original need not remove iron to install a removal of iron, developed to install 3 ~ 4 multistage series in addition to iron, in addition to an iron tank iron magnet rod also developed from the original ten or twenty to two or three hundred, more and more large investment.
2, due to the mine resource consumption is too fast, many enterprises have been unable to find nearby and unable to buy low iron standard raw materials, had to use downstream treatment, a large number of use in addition to iron, a line in addition to iron process has reached more than a dozen choose as workers, in addition to iron cost is getting higher and higher.
3, the cleaning method is all by artificial selection, quality is difficult to guarantee. Usually a group of 100 ~ 300 magnetic bars, 1 ~ 3 workers per shift, one by one, constantly take turns to clean, about 1 ~ 2h to wash, when the raw material containing high iron, often appear around the magnetic bar paste iron clay impurities thick layer, iron removal effect significantly decreased. In addition, there are many emotional factors that make quality management difficult to control.
4. The quality of the magnetic bar sold in the market is unstable, with too many manufacturers and too many brands. There are also many products made in poor quality, and the sealing of the two ends of the bar is not strict. After these products flooded the market, the average life of the magnetic bar used by enterprises decreased continuously, followed by the "nominal" value of the magnetic bar B in the market was generally high, mostly (50 ~ 100) % higher than the measured value.
5, dry iron in addition to the use of et vibration cabinet (frame) type permanent magnet iron removal and belt drive in addition to iron, is mainly used to remove the powder in the long distance transmission process of infiltration of rust impurities particles, the effect is good, the use of units are also increasing and expanding.
6, in addition to the development of electromagnetic iron trial time is early, the reaction can be, especially the high power strong magnetic field on the separation of raw ore in the presence of weak magnetic materials, but the investment is too large, more power consumption, service life is not long, thus affecting its promotion and application.
7, the world's developed ceramic raw materials are centralized processing standardized production, in addition to their iron equipment for large specifications, large flow, high power, automatic electromagnetic iron, large volume, expensive, less than hundreds of thousands, more than millions of yuan.
