[0001] The utility model relates to the field of grinding devices, and more specifically, to a polishing powder grinding device. Background Art

[0002] Polishing powder grinding devices are usually made of high-strength, wear-resistant materials such as alloy steel and ceramics. Their shapes can be cylindrical, conical, etc. Reasonable design of the shape is conducive to the flow of materials and the grinding effect. Polishing powder grinding devices have the characteristics of reasonable structure, advanced working principle, efficient grinding, uniform particle size, strong adjustability, energy saving and environmental protection, etc., which can meet the grinding needs in the polishing powder production process.

[0003] When discharging, the polishing powder grinding device requires manual installation of a partition net onto the discharging mechanism, which affects production efficiency and increases labor costs. Manual installation of the partition net usually requires workers to operate near the equipment, which may bring certain safety risks. Therefore, it is necessary to design a polishing powder grinding device with automatic deformation function to solve the above problems. Utility Model Content
