The rotating shaft drives the impact column on the impact plate to rotate and impact on the arc plate, causing the impact ball on the arc plate to impact on the ball mill inner barrel, generating a vibration force to shake off the solid electrolyte material adsorbed on the inner wall of the ball mill inner barrel, avoiding the adsorption of solid electrolyte material on the inner wall of the ball mill inner barrel, and the excessive adsorption may cause the phenomenon of clumping, thereby affecting the ball milling of solid electrolyte material.

[0004] However, in actual use, the rotation of the rotating shaft drives the rotation of the grinding disc and the grinding rod, and the movement of the grinding balls with the rotation of the grinding disc and the grinding rod causes them to collide with each other and impact on the solid electrolyte material, generating an impact force to grind the solid electrolyte material. However, the overall structure only realizes single-direction rotation around the rotating shaft, which has the problem of insufficient ball milling. Utility model content
