[0002] With the vigorous development of the new energy industry, battery manufacturers have an extremely urgent need for a stable and safe lithium supply. The salt pressure cooking process currently used in lithium mica mines effectively extracts valuable elements such as potassium, lithium, rubidium and cesium from lithium mica mines. However, a certain amount of sodium salt and alkali remain, and open-air stacking and landfilling will threaten the safety of the surrounding environment and groundwater resources. Therefore, it is necessary to explore equipment that can recycle and reuse lithium mica slag. The current various recycling methods are still mainly in the laboratory stage. The current slag recycling method is mainly to grind the slag into powder and use it as a building material or as a raw material for ceramic production.

[0003] When recycling slag, it is generally necessary to grind the slag to obtain sufficiently small powdered raw materials to meet the needs of subsequent processing. Current grinding equipment generally grinds in a tank structure. After the raw materials are put into the tank, they are ground by internal grinding parts such as grinding discs, and then the ground powder is output. However, when using this type of grinding equipment, the powder obtained by grinding is sometimes adsorbed on the inner wall of the tank and cannot fall smoothly, resulting in inconvenience in use, and this part of the raw materials is also prone to insufficient grinding.

[0022] The device uses a grinding structure 2 in the tank body 1 to grind and crush the smelting slag to obtain the required powder. A blowing structure 3 is also provided above the tank body 1. The blowing structure 3 can control multiple nozzles 31 to blow air to the side of the tank body 1 at the same time. The blowing range covers various areas of the tank body 1. Therefore, the powder originally adhered to the inner wall of the tank body 1 can be blown down, so that this part of the powder can be fully ground and discharged normally.

[0023] The nozzle 31 is connected to the rotating shaft 37, and the rotating shaft 37 can rotate on its own, and the rotation process is controlled by the ring gear 351 on the driving ring 35 and the driven gear 38 on the rotating shaft 37. During operation, the rotation of the ring gear 351 in a small range can control the rotation of the nozzle 31, so that the nozzle 31 sprays air to different areas. The change of airflow makes the coverage area of ​​the nozzle 31 larger, the blowing is more sufficient, and the dust removal is more thorough.

[0024] As another embodiment of the present invention, please refer to Figure 1 to Figure 3 In the second embodiment of the utility model, a primary motor 33 is installed on one side of the tank body 1, and the primary motor 33 is connected to a driving gear 34 located inside the tank body 1, and the driving gear 34 is meshed with a gear ring 351. The primary motor 33 drives the driving gear 34 to rotate, and can control the rotation of the driving ring 35.

The secondary motor 21 drives the grinding disc 24 to rotate through the driving shaft 22, and grinds the smelting slag between the grinding disc 24 and the grinding seat 25. The hydraulic rods 26 support the grinding seat 25, and can also make the grinding seat 25 rise and fall within a certain range to change the fineness of grinding, and can also be used to discharge the ground powder. The present device does not limit the specific structure of the grinding structure 2, and the above structure is only used as a display of a structure with a grinding effect.
