[0004] The magnetic separator usually consists of a magnetic field system, a feeding tank, an ore pulp tank and a discharge device. The magnetic field system generates a strong magnetic field that attracts magnetic minerals to the magnetic poles, while non-magnetic minerals are repelled outside the magnetic field.

[0029] Compared with the traditional feeding tank, the short pipe and the straight pipe are cancelled, the problem of short pipe blockage is not worried, the work of clearing blockage is saved, the working efficiency of the magnetic separator is ensured, meanwhile, the ore pulp concentrated in the receiving area is guided by the guide plates 3, the ore pulp flowing out of the flow outlet 11 is relatively uniform, and the ore pulp will not flow out from a certain place of the flow outlet 11.

[0030] In an embodiment, the receiving area is provided with a conical slope 4, the conical slope 4 is in the shape of a semi-circular conical block, one vertical side of the conical slope 4 is attached to the side wall of the flow outlet 11 of the flow distribution groove 1, one end of the plurality of guide plates 3 is distributed in a fan shape around the conical slope 4, the conical slope 4 is located directly below the material conveying pipe 2, and the ore pulp output by the material conveying pipe 2 spreads in all directions along the slope surface of the conical slope 4 from the top of the conical slope 4. By virtue of the conical slope 4, on the one hand, the ore pulp can be uniformly introduced into the guide flow channels of the guide plates 3, and on the other hand, the ore pulp washed in all directions along the slope surface of the conical slope 4 can stir the ore deposited at the bottom of the receiving area, effectively preventing the ore pulp from depositing at the receiving area and the front end of the guide flow channels, and ensuring the uniformity of the ore pulp entering the guide flow channels.

[0031] In an embodiment, the bottom of the flow distribution groove 1 is formed with a slope, one end of the slope with a higher height is located at the receiving area, and the other end of the slope with a lower height is located at the flow outlet 11, and each guide plate 3 is arranged on the slope.

[0039] In specific implementation, the flow guide component 6 can be designed in a funnel shape, which can further ensure the uniformity of the slurry flowing into each flow guide channel from the receiving area.

[0040] In an embodiment, the top of the flow channel 1 is provided with a channel cover 7, and one end of the material conveying pipe 2 penetrates through the channel cover 7 and enters the flow channel 1.
