what is magnetic separation used for？

Problems and solutions in the production of vertical ring high gradient magnetic separator.

1) In practice, the pulsating stroke of the stroke box is realized by the adjustment of the slider, which is extremely inconvenient, so when the ore property changes, it is easy to cause the tailings to be high and the concentrate grade to be unstable. It is recommended to change to a high-frequency digital pulse stroke box in the future to make adjustment more convenient and timely;

2) Another important factor affecting the two grades of end-end and concentrate is that there are no cylindrical sieve slags in the current selection of the magnetic separator. The slag-free equipment is easy to cause the rod medium and the screen mesh, and once the rod medium is extremely difficult to dredge, each machine has 40 magnetic medium plates, each of which is densely welded with a magnetic stainless steel rod. The finished product price is about 2000. Yuan/block, such as serious, only the replacement cost is higher. In addition, the company does not have slag-containing equipment, and it is easy to cause large particles of magnetic particles to enter the iron fine powder warehouse, resulting in a decline in the grade of iron fine powder. It is recommended to add a slag system;

3) Through the production application, the adjustment of the rotating speed of the machine is only inconvenient by replacing the pulleys of different diameters, and the laborious and time-consuming spare parts are also easy to be damaged. It is recommended to change to an electromagnetic speed regulating motor to achieve free and convenient stepless speed regulation, and better to adapt to changes in ore properties and slurry concentration;

4) The rectifier cabinet of the machine outputs a low-voltage, high-current excitation system, and the rectifier cabinet wire package is severely heated. This machine adopts water-cooling system, which is easy to block after circulating water in the coil, causing fault alarm. Thereby affecting the production rate of the machine. Can be changed to air cooling system or electronic component cooling system;

5) This type of machine uses a semi-closed vertical magnetic field magnetic system with low voltage and large current excitation, but the highest background field strength is 1.069T. It is recommended that the manufacturer further increase the background field strength to make it more widely used and wider.

6) The recovery effect of the vertical ring pulsating high gradient magnetic separator on fine-grained hematite below 0.074 mm is not satisfactory, that is, less than 30% is recovered below 0.074 mm, and the remaining 70% is lost from the tailings, to a large extent Affected the comprehensive recovery of hematite.
