Since the reform and opening up, has been in the field of mining machinery market for technology as the main way to improve the level of product technology, will face foreign competitors, especially foreign competitors to invest and set up factories in the country's crisis. Magnetic force size sand magnetic separator magnetic source provided is appropriate. As we all know: The magnetic field from entering the four-roll type dry magnetic separator machine, the size of the force depends on the size of the magnetic field strength at that point, but the size of the magnetic field strength depends not only on the level, but also with the point magnetic sand sorter magnetic field gradient has a close relationship. Technological base mining equipment industry is not thick, sand separator feeding affect the thickness of productivity have much, much thicker in order to achieve the best results, and will not waste feed before, and not waste separator area. Ensure the sand separator magnetite powder fineness requirements. After the magnetite particle coarsening by suspension slime content increases, sculping sieve and magnetic separator efficiency is reduced, magnetite losses will increase significantly. Such as magnetite fineness below standard, should increase the grinding part. While in the water resistance of a larger movement suffered permanent magnetic separator machinery, so when you need a larger magnetic recovered and the water is easy to be swept away by iron dry magnetic separator, causing metal loss. Visible, magnetic separator grinding process to minimize excessive wear. New laboratory improvement and should give due consideration to the high start, based on practical, including the theory test, test methods, laboratory equipment, pilot scale and control and detection technology, if necessary, should the introduction of foreign advanced technology of magnetic separator. Micro-fine particles of magnetite magnetic separator weak, small disk pole spacing, no zero magnetic zone between disk and disk. Mining machinery industry weak link, there is no application of the technical data and databases, to convince customers to use our products and technology, but also not to mention the truly innovative application of technology. The pace of development of mining machinery will slow down, so now begin to consider the needs of the industrial era mining machinery domestic and international markets and not too early. The current increase in market demand makes mining equipment manufacturing market hot, especially as high gradient magnetic separator and other processing equipment showing a shortage situation. Blind pursuit of high-gradient magnetic field strength and ignore the construction field is obviously a very low-level error. However, most of the domestic manufacturers did not adequately consider magnetic design of the magnetic source, a direct result of the low-energy magnetic separator magnetic separation equipment.
