[0026] Among them, the grinding box 11 is fixed with a control device for controlling the overall equipment. The telescopic structure in this application is a hydraulic cylinder, which is the prior art.

[0027] Specifically, there are two sets of grinding rollers 123, which are arranged in parallel. A material strainer is placed at the bottom of the lower grinding roller 123 to ensure the grinding quality of graphite powder.

[0028] Furthermore, the first discharge pipe 13 is disassembled and installed with the powder storage box 15 through the hollow threaded connector 14, which facilitates the replacement of the powder storage box 15 in the future.
