[0013] A wet-process mica powder grinding and grading device comprises a wet mica slurry stirring structure 1, a mixed solution pumping group 2, an upper water return pipeline 3, a grading water pool 4, and a grading basket 5. The mixed solution pumping group 2 and the upper water return pipeline 3 are both connected between the wet mica slurry stirring structure 1 and the grading water pool 4. The mixed solution pumping group 2 is connected to the side bottom end of the wet mica slurry stirring structure 1 and the side top end of the grading water pool 4. The upper water return pipeline 3 is connected to the side top end of the grading water pool 4 and the side top end of the wet mica slurry stirring structure 1. The grading basket 5 is arranged in the grading water pool 4.

[0014] The wet mica slurry stirring structure 1 is composed of a stirring barrel 6, a stirring motor group 7, a motor group fixed bracket 8, and a stirring blade shaft 9. The stirring motor group 7 is fixed on the top side of the motor group fixed bracket 8, and the stirring blade shaft 9 is connected to the bottom side of the stirring motor group 7. The motor group fixed bracket 8 is fixed on the top side of the stirring barrel 6, and the stirring blade shaft 9 is arranged in the stirring barrel 6. The mixed solution pumping group 2 is composed of a water pump 10, a connecting pipe 11, and a dispersing jet component 12. The water pump 10 is connected to the middle section of the connecting pipe 11, and the dispersing jet component 12 is connected to the side end of the connecting pipe 11. The connecting pipe 11 is connected to the bottom end of the side of the stirring barrel 6, and the dispersing jet component 12 is fixed to the top side of the side end of the grading water tank 4. The upper water return pipeline 3 is composed of a water pump 10 and a connecting pipe 11. The water pump 10 is connected to the middle section of the connecting pipe 11, and the side end of the connecting pipe 11 is connected to the top edge of the side of the stirring barrel 6.

[0015] The grading basket 5 is composed of a sedimentation basket 13 and a lifting handle 14. The lifting handle 14 is symmetrically fixed on the top sides of both ends of the sedimentation basket 13. A plurality of groups of graded sedimentation grids 15 are arranged in the sedimentation basket 13. A plurality of groups of graded sedimentation grids 15 are arranged in the sedimentation basket 13.

[0016] Working principle of the utility model: the working principle of the device is to utilize mica powder to be sprayed into a water pool, and utilize the particle size of the mica powder and the fluidity of water to achieve classification.

[0017] First, water is added into the mixing barrel 6 and the grading water pool 4, and the amount of water added should be above the connecting pipe 11 at the rear end of the grading water pool 4. Then, wet mica powder is added into the mixing barrel 6, and the stirring motor unit 7 is driven to make the stirring blade shaft 9 stir the wet mica powder. The mica powder is mixed and stirred until it becomes turbid. The turbid mica solution is extracted by the water pump 10 and supplied to the dispersing jet part 12 through the connecting pipe 11. The turbid mica solution is sprayed out of the grading water pool 4 through the dispersing jet part 12. The mica powder with larger particles will be dispersed in the water flow. The mica powder particles are precipitated in the grading sedimentation grid 15 in the sedimentation basket 13 by the water flow in the grading water pool 4. Therefore, the mica powder particles precipitated in the grading sedimentation grid 15 in the sedimentation basket 13 gradually become smaller until the injection begins. After the grading basket 5 is slowly taken out, the water in the sedimentation basket 13 will flow out through the drainage holes 16 on both sides, and the mica powder will be precipitated in the grading sedimentation grid 15. The corresponding mica powder is taken out for drying.
