Wet Permanent-magnet Drum Separator is made up of cylinder, magnetic system, tank body and transmission. The cylinder is made by stainless steel plate welded into a tube (different thickness for different model), the cover is aluminum casting object, and be connected with cylinder by hexagon bolts, through the speed reducing machine, the electric motor drives the cylinder doing rotation motion. The magnetic system is open-ended type, and be installed into the cylinder, magnet block is installed on the floor of the magnet wheel by stainless steel bolts. The axis of the magnet wheel is outside the cylinder, turn arm is fixed on the end of axis, so the magnetic system declination can be adjusted by turning the turn arm, and it can be fixed by pull rod once the adjustement is done. The working area of the tank body is made of stainless steel (different thickness for different model), the other parts of the tank body and machine frame is welded by regular steel.
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.
