electromagnetic screen
1.The application of Lukai MVS2020 high frequency electromagnetic deck - vibrating screen in Eicon Iron Mine is described.
2.MVS electromagnetic high frequency vibrating screen is a new high capacity machine and has the advantages of electromagnetic vibration, high frequency, high capacity and high screening efficiency.
3.In order to further raise the high-valence iron concentrate quality, reduce the foreign inclusion, increase enterprises economic efficency, the MVS 2020 electromagnetic vibrating wire screen is adopted to substitute for the section of cyclones, in solving the problem of the counter-negtive collection of the cyclone grading, realizing the selective rubbing and enhancing the final rubbing product granularity. The test results indicate that the rubbing fineness is increased compared with that from the original process, and the reground iron ore concentrate quality is obviously improved.
4.The visual method was developed to compute the glint error of complex targets by the phase gradient method in GRECO(graphical electromagnetic computing) system in high frequency region. This method made each pixel of screen as one scatter center of target and the number of scatter centers was greatly increased to the pixel level,then the result accuracy was improved and the visual computation course was implemented.
5.In this study, we use different particle of Carbon powders mixed with Epoxy-resin, and coating on polyester woven fabrics for designing the electromagnetic wave absorbing screens, and employ the matching of impedance to designing the transfer of single or plural layers, and observe the influence of the amount of layers and the methods of collocating screens, to attain the method of collocating screen, which achieve best effect of absorbing of electromagnetic wave.
6.Not only can CFRW improve tensile strength,compressed strength of materials, but also it can enhance the properties of wood, such as defensibility against bacteria and ants, water, erosion, and capability in conduction of electric current and screen of electromagnetic wave.
7.The explanation for this “spooky action at a distance” (to borrow a term from quantum mechanics) is that a grid of wires underneath the screen emits an electromagnetic field that causes a coil inside the pen to oscillate at a resonant frequency.
8.SB2011 Precise Decade Inductance Box adopts loop inductance coil, EMC screen, special temperature compensation structure, aging technology, and whole-seal moistureproof measure Therefore, it possesses many special characteristics, such as strong anti electromagnetic capability, little effect by humidity and temperature, perfect stability, reliable performance, strong adaptability, novel structure, and easy to operate.
9.Introduced the antijamming in the numerical control system design, from the shield (including electric field shield, magnetic screen and electromagnetic field shield) designs mentions, added the absorbing circuit to the perceptual load to suppress the transient state noise to give the specify, might avoid the numerical control system which disturbed creates "softly" the breakdown.
