Dry iron ore magnetic separator magnetic field strength is above 3500 gauss at general requirements, the selection is called middling with a common grade at around 20%.
The main ore-dressing process is as follows:
Load crude ore into the hopper, after vibration motor vibrates fabrics,fine-tuning of discharge amount can be managed through handwheel.
Dry magnetic separator roller drag through buncher dragging, rotate speed was adjusted by timing meter, the output of magnetic separator and concentrate grade can be controlled. Mineral tablets was load by conveyor belt to sort on the magnetic roller, as the ore magnetic particle, high magnetic field was immediately adsorbed on the magnetic roller, and gangue tablets (miscellaneous stone, sand) are absent of magnetic (weak magnetic), magnetic roller magnetic suction does not produce it, With the rotating magnetic roller, mining tablets have been attracted on the magnetic roller, and the stone tablets of the pulse in the magnetic roller to the front when it was thrown out the location of every mine in the front plate (separated by changing the size of mine adjustable angle plate Concentrate grade), mineral grains continue to be taken off the magnetic roller sector Selected automatically fall into a collection bucket for the ore mining products. As a result of falling on the magnetic roller gangue entrainment also some weaker magnetic particle, they will continue into the next magnetic roller for magnetic separation. Magnetic separation of the finished product after the tablets into the selected works of mine ore bucket collection for the finished product, have been left of the gangue by tailings from the mouth at the end of this magnetic separation processes. As a result of the gangue in the ore was abandoned, so to make ore grade improved.
