A screw conveying shaft is installed in the conveying cylinder, and the upper part of the conveying cylinder is provided with a discharge port, and the level of the discharge port of the conveying cylinder is higher than the level of the washing water.

The upper and lower installations of a weak magnetic separation roller and a strong magnetic separation roller in the machine are combined into one group, and the combination is not less than one group in the machine.

The ore powder and slag after the weak magnetic separation part beneficiation enter the strong magnetic separation part from the discharge port below the material box of the weak magnetic separation part, just fall on the upper surface of the strong magnetic separation roller, fully contact with the strong magnetic separation roller, and the powder The useful minerals in the ore and slag are fully adsorbed on the surface of the strong magnetic separation roller. During the rotation of the strong magnetic separation roller, the useful minerals are brought to the other side of the strong magnetic separation roller, and after being washed with water, they fall into the outlet of the washing box. At one end of the material inlet, the remaining residue falls into the end of the slag outlet, part of the mud in the washing water is taken away by the washing water, and part sinks into the end of the slag outlet, and the useful magnetic minerals and residue are respectively output by the conveying cylinder.

Since each functional part of the machine adopts the structure design of the upper and lower levels, it occupies a small space and is suitable for on-site use in mining sites, greatly reducing the workload of raw material transportation; it adopts two-stage mineral processing of weak magnetic separation part and strong magnetic separation part , and the working method of feeding closely to the magnetic separation roller greatly improves the beneficiation efficiency and reduces the amount of missing beneficiation; adopts the functional design of the upper spray water beneficiation and water tank beneficiation, the water for spraying ore washing flows into the ore washing water tank, and the ore washing water tank The ore washing water inside flows in and out from the upper layer, and the mud and slag sink into the bottom of the water tank, and are immediately discharged from the output of the conveying cylinder, which can greatly reduce the amount of water used and is conducive to the recycling of water resources; the upper discharge plate is adopted And the discharge method of the lower discharge port can select ore resources of different grades and improve the efficiency of selection.
