In the optional scheme of the embodiment, the first magnetic separator also includes frame 201, and height regulation is provided with frame 201
Mechanism, the height for adjusting rotating roller.
Specifically, transmitting device and collecting mechanism are mounted in frame, and permanent magnetic roll assembly of roll magnetic separator, rotating roller and material conveyor belt
The top of collecting mechanism is respectively positioned on, and permanent magnetic roll assembly of roll magnetic separator and rotating roller are connected by bearing block with frame；Permanent magnetic roll assembly of roll magnetic separator is located at magnetic
The boundary of material collection funnel and non-magnetic material collection funnel, rotating roller is located at the top of non-magnetic material collection funnel,
For enabling non-magnetic material to enter into non-magnetic material collection funnel.Height adjustment mechanism includes lifting screw 202 and rises
Drop seat 203, lifting screw 202 is arranged in the fixed plate 204 in frame, and company is fixed in one end of lifting screw with lifting seat
Connect, the bearing block 205 of rotating roller is fixed on lifting seat 203；When using, by screwing the nut on lifting screw, can adjust
The upper-lower height of lifting seat is saved, such that it is able to adjust the height of rotating roller；The axis of rotating roller and the diameter parallel of permanent magnetic roll assembly of roll magnetic separator, and
It is horizontally disposed with.The quantity of height adjustment mechanism is two, and two height adjustment mechanisms are respectively arranged on the two ends of rotating roller.In order to
Ensure the stability of lifting seat, lifting seat is also detachably fixed by bolt with frame and be connected, opened up in frame for wearing
The hole of bolt is mounting hole, in order to after the bolts have been loosened, lifting seat can move up and down.It is first when adjusting the height of lifting seat
The bolt between lifting seat and frame is first unclamped, the nut on lifting screw is then screwed, to adjust the height of lifting seat, works as tune
After section is good, the nut of fixed plate both sides is tightened, the bolt between lifting seat and frame is finally tightened again.Rotated by adjusting
The height of roller, it is possible to achieve the flow velocity of regulation slurry；In addition, the direction of motion phase of the flow direction of slurry and material conveyor belt
Together.
It should be noted that in the embodiment, it is also possible to be respectively provided with a same height regulation at the two ends of permanent magnetic roll assembly of roll magnetic separator
Mechanism, to adjust the height of permanent magnetic roll assembly of roll magnetic separator；In addition, magnetic material collection funnel and non-magnetic material collection funnel can be using cones
