Boron carbide ultrafine powder automatic sorting system

Abstract

The invention provides a boron carbide ultrafine powder automatic sorting system. The system comprises a water adding system, a feeding system, a settling system and a collecting system, wherein the water adding system is used for adding water to the settling system, the feeding system is used for adding materials to the settling system, the settling system is used for stirring and mixing the water and the materials and discharging qualified slurry, and the collecting system is used for collecting and treating the discharged slurry. According to the system, by means of the water adding system,the feeding system, the settling system and the collecting system working in a coordinated mode and the programmed control, needed boron carbide ultrafine powder can be screened rapidly and efficiently, then the needed boron carbide ultrafine powder is obtained, and the system is simple and ingenious in structural design and has the advantage of saving energy.

Description

technical field [0001] The invention belongs to the technical field of boron carbide abrasive powder production, and in particular relates to an automatic sorting system for boron carbide ultrafine powder. Background technique [0002] Boron carbide ultrafine powder is suitable for rapid grinding, thinning and polishing of cemented carbide and gem materials. Different from its use in sintered ceramics, coating raw materials, and additives, when boron carbide ultrafine powder is used as an abrasive, especially when thinning and polishing sapphire materials, there are extremely strict requirements on the particle size distribution, which requires The large-scale industrial production of boron carbide ultrafine powder abrasives has brought extremely high difficulties. [0003] In the production of boron carbide superfine powder, water is used to grind the powder, and the boron carbide superfine powder and water are placed in the sorting cylinder for stirring, and the pumping t...

AI Technical Summary

Problems solved by technology

[0003] In the production of boron carbide superfine powder, water is used for the ground powder, and the boron carbide superfine powder and water are placed in the sorting cylinder for stirring, and the pumping time is adjusted according to the required particle size specification, and the siphon is used in the inlet Manual pumping at the material inlet and manual timing require skilled operators, but various operating errors will still occur, affecting product quality and labor-intensive; in addition, in the existing production process of boron carbide ultrafine powder, there are high costs. , low efficiency and other disadvantages
