Analysis of Factors Affecting the Productivity of Weak Magnetic Ore Magnetic Separator


The productivity of weak magnetic ore magnetic separator is related to many factors, among which: 1) the particle size of the ore selected; 2) the content of magnetic components in the ore; 3) the speed of the ore passing through the working area of ​​the magnetic separator; 4) magnetic Part of the speed discharged from the working area of ​​the magnetic separator.


The difference between the weak magnetic ore magnetic separator and the ferromagnetic ore magnetic separator is that the former does not use multiple layers of ore feeding even when selecting fine materials, but only one layer or 2-3 layers. There are many reasons for this. The main ones are as follows: 1) the magnetic force is less than the gravity; 2) as the magnetic pole of the magnetic separator is far away, the magnetic force drops sharply and the magnetic pole required for the multi-layer feeding is more It is difficult to generate sufficient magnetic force at a large distance; 3) The magnetic ore particles in the working area of ​​the weak magnetic ore magnetic separator are discharged by a disc, a ring or a rotating roller, and these components attract the magnetic ore particles in a short length, for example: for a roller The magnetic separator is 40-60% of the feed width and smaller for the disc magnetic separator. If a weak magnetic ore magnetic separator is designed, the magnetic force in the whole volume of the magnetic field is larger when the pole distance is larger, and the surface of the magnetic ore particles in the working area is excluded. High productivity.
