[0028] In the embodiment, the cooling can be realized by oil cooling, the heat exchange between air and oil in the coil is realized, no cooling water is consumed, and safety is good at low temperature.

[0029] The cooling system 60 further includes a first flow valve 65 installed on the oil inlet pipe 62 close to the winding coil 61 and a second flow valve 67 installed on the oil return pipe 63 close to the winding coil 61.

[0030] The cooling system 60 further includes a flow meter 66 installed on the oil inlet pipe 62 close to the condenser 64, so that the oil amount passing through the flow meter 66 can be observed, and subsequent operation of the user is facilitated.

[0031] The winding coil 61 adopts a closed stainless steel shell, the coil winding is completely immersed in transformer oil, the oil return pipe 63 and the oil inlet pipe 62 are connected with the condenser 64 to realize external heat exchange, and the winding coil 61 has excellent moisture-proof, rain-proof, dust-proof and corrosion-proof performance.

The breather 69 can communicate the coil with the atmosphere and filter out the moisture in the air, the breather 69 is filled with white silica gel particles, when the color of the desiccant changes to light yellow or pink (the color changes after absorbing a certain amount of moisture), the breather 69 should be replaced in time to ensure the normal work of the cooling system 60.

[0033] In the above embodiment, the magnetic yoke assembly comprises an upper magnetic yoke 30 and a lower magnetic yoke 40 which are spaced mounted on the rack assembly 10, the feeding system comprises a mine feeding hopper 70 and a water flushing hopper 80 which are mounted on the magnetic separation barrel 20 of the rack assembly 10, and the high gradient magnetic separator for water abrasive of lepidolite comprises a magnetic mineral collection box 100 which is mounted above the rack assembly 10 and a non-magnetic mineral collection box 110 which is mounted below the rack assembly 10.

[0034] The coil adopts full-sealed oil cooling external circulation, the magnetic field generated by the winding coil 61 forms a loop through the upper magnetic yoke 30 and the lower magnetic yoke 40, in operation, the rotating ring assembly 50 rotates in a preset direction, the ore pulp enters the mine feeding hopper 70 through the feeding pipe, and the ore pulp flows through the lower part of the rotating ring along the gap flow channel in the magnetic system, the magnetic medium box 120 mounted on the rotating ring is magnetized in the induction area, a high gradient magnetic field is formed on the surface of the magnetic medium, when the ore pulp flows through the medium box, the magnetic particles are adsorbed on the surface of the magnetic medium, and are taken to the top of the non-magnetic field area by the rotation of the rotating ring, the magnetic material is flushed into the magnetic mineral collection box 100 through the pressure water, and the non-magnetic particles flow into the non-magnetic mineral collection box 110 along the lower gap of the magnetic system and are discharged.
