How to choose a cosmetic sander, please refer to the following points:
1. Stability: Whether there is a long-term shutdown fault in the sand mill, whether the screen meets the requirements, and whether the internal structure design is reasonable.
2. Fineness of the ground finished product: whether the material of the ground finished product is uniform, whether the particle size is consistent, and whether the ground area is fully covered.
3. The purity of the finished product after grinding: whether the purity is pure, and whether there is any contamination of the finished material caused by component quality issues.
4. Accessory wear: Whether the wear rate of the main components of the sand mill is clear depends on the material of the core components of the sand mill.
5. Mechanical sealing performance: Is there any material leakage caused by mechanical sealing performance issues.
6. After sales service: Can the sand mill manufacturer respond promptly to customers' problems during the grinding process and solve them professionally.
