how magnetic separator works
Operational principle of magnetic separator
Through the feed box, ore pulp flows into tank, under the water flow effects of the feeding spray pipe, ore grains enter into the feeding area of the tank under loose condition. Due to the effects of magnetic field, magnetic ore grains congregate and form “magnetic cluster” or “magnetic linkage”. The “magnetic cluster” or “magnetic linkage” moves to the magnetic pole inside ore pulp under the magnetic effects, and be absorbed on the cylinder. Due to the polaritity of the magnetic pole are alternately arraied along the roation direction of the cylinder, and be fixed tightly while in operation. When the “magnetic cluster” or “magnetic linkage” is rotating along with the cylinder, because of the magnetic stirring phenomanon created by the alternating of the magnetic poles, non-magnetic minerals like gangue which are mingled with “magnetic cluster” or “magnetic linkage” will fall off during the motion of flipping, Eventually the remained “magnetic cluster” or “magnetic linkage” absorbed on the surface of the cylinder is ore concentrate.
The ore concentrate will be rotated to the weakest magnetic spot on the edge of magnetic system along with the cylinder, and be discharged to the concentrate chute under the washing water effects which is creatd from the discharging water pipe. Non-magnetic or weak-magnetic minerals are discharged out of the tank along with the ore pulp, and be known as ore tailing. The remained magnetic minerals of tailing can be retrieved by being through one more time magnetic separator, so the recovery rate is improved. On the other hand, the gangue mingled with concentrate can be removed by being through one more time magnetic separator, so the concentrate grade is improved.
