demagnetiser


It is a kind of equipment used to eliminate the residual magnetism of magnetic iron ore particles after magnetic separation. After the magnetic iron ore particles are sorted by the magnetic separator, the ore particles have magnetic agglomeration due to residual magnetism, which affects the operating efficiency of the next process, so it is necessary to demagnetise the ore particles before entering the next process. Demagnetiser is a tower-shaped coil set on a non-magnetic tube. Coil through the alternating current, in the coil axial direction along the slurry flow direction to produce continuous changes in the direction and the value of the magnetic field gradually become smaller, from coil Ⅰ to coil Ⅴ field strength from high to low, and leave the last group of coils Ⅴ, the field strength gradually attenuated to zero.
