Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a glass bead grinding and polishing device for a sand mill. Background Technology

[0002] Sand mills, as a highly efficient grinding and dispersing device, are widely used in many industries such as coatings, inks, ceramics, and electronic materials. Glass beads, as a commonly used grinding medium in sand mills, have a surface condition that directly affects grinding efficiency and product quality.

[0003] Existing grinding and polishing equipment often uses a method of placing multiple glass beads inside the device to carry out grinding and polishing operations. During operation, the glass beads are in a state of high-speed movement. Due to the limited space, the glass beads are very likely to collide with each other. Continuous impacts will form a lot of scratches on the surface of the glass beads. Even after the grinding and polishing process is completed, these tiny scratches caused by impacts will further develop into some tiny gaps, resulting in low quality of glass beads that cannot meet current needs.
