Factors that influence magnetic separator working efficiency

Impact separator efficiency factors:

1, the impact of magnetic separator http://www.cnballmill.com/Pro3/16.html work space for sorting effect size
1) Work gap is too large, small magnetic field strength near the bottom, high-grade ore, but, tailings grade increased, reducing the recovery rate.
2) work space is small, the magnetic field strength near the bottom of the large and small tailings loss, high recovery rate, but concentrate grade will be reduced. Working gap is too small, one affects the processing capacity; Second, pulp greatly accelerated in sorting space velocity, magnetic mineral particles will be brought to the tailings, tailings increased metal loss, and even did not break out because of tailings a "full tank" phenomenon.

2, sorting size and concentration grind size affect the thickness of the magnetic effect
Sorting concentration, big resistance, not loose mineral particles, sorting is not sufficient, concentrates easily mixed with gangue, resulting in low concentrate grade; sorting concentration affects the processing capacity is too small, although concentrate grade can be higher, The tailings grade will be increased, the concentration is too small for sorting sorting dewatering tank more negative, can not form a seam, in the role of water to disperse, so that part of the magnetic mineral particles went to the tailings, tailings resulting rise recoveries declined.
Coarse grind size, useful minerals could not reach monomer dissociation, low-grade ore, tailings high sorting poor results. Too small will cause excessive crushing, sorting difficulties, too small particles will run away from the tailings, tailings resulting high grade, metal recovery decline.

3, to disperse water rinse unloading ore mine and the impact of water on the sorting index
Disperse the water too, slurry flow rate is too fast, the tailings will increase, disperse water slurry of mineral particles too small to not loose, easy to produce mixed so low concentrate grade and high-grade ore deposition bottom water will not be suspended When together, but also make high grade tailings. Water rushed election unloading ore concentrates mainly used for removing the skin from the tube, rinse water unloading ore too bad, so that the cylinder belt ore sorting impact indicators, flush water through the operation of the Assembly to the next job difficult, rinse The size and direction of the water should be able to ensure that you can concentrate unloaded off.
