Abstract
Description
Technical Field
[0001] This utility model relates to the field of diamond micron powder production technology, specifically a grinding device for diamond micron powder production. Background Technology
[0002] Diamond micron powder refers to diamond particles with a size finer than 54 micrometers. It includes both single-crystal and polycrystalline diamond micron powder. Due to the large production volume and wide range of applications of single-crystal diamond micron powder, the industry generally refers specifically to single-crystal diamond micron powder. Single-crystal diamond micron powder is produced by hydrostatic pressing of synthetic single-crystal diamond abrasive grains, followed by crushing, shaping, and special processes for superhard materials. Diamond micron powder has high hardness and good wear resistance, and can be widely used in cutting, grinding, drilling, and polishing. It is an ideal raw material for grinding and polishing high-hardness materials such as cemented carbide, ceramics, gemstones, and optical glass.
[0003] The processing of diamond micron powder usually requires grinding diamonds into micron powder using a ball mill. Steel balls repeatedly rise and fall inside the ball mill to strike the diamonds, thus achieving grinding. However, there are gaps between the steel balls, making it difficult to grind small diamond fragments. Furthermore, diamond micron powder is usually statically charged, and floating diamond micron powder tends to adhere to the equipment surface, resulting in waste. To address this, we propose a grinding device for diamond micron powder production. Utility Model Content

The feed pipe 25 is connected to the feeding device, and the discharge pipe of the discharge port 37 is connected to a vacuum feeder. The motor 5 is started, and the output shaft of the motor 5 drives the grinding cylinder 23 to rotate. The rotation of the feed pipe 25 delivers the diamond to be ground from the feeding device into the grinding cylinder 23. Inside the grinding cylinder 23, the steel balls repeatedly rise and fall as the grinding cylinder 23 rotates, grinding the diamond. A filter groove is provided along the edge of the partition plate 22 to filter the diamond micron powder and smaller gold particles produced. Diamond fragments enter the rear end of the grinding cylinder 23 through the filter tank. Small-diameter steel balls grind the smaller diamond fragments again to obtain diamond micro powder.
