Abstract

The invention discloses a high-strength ultra-fine grinding medium, which is composed of the following raw materials in parts by weight: alumina, zirconia, zirconium silicate, silicon carbide, silicon nitride, silicon oxide; ceramic powder, deionized water, isobutylene Perform ball milling and defoaming with maleic anhydride copolymer and aluminum sol to obtain ceramic slurry, and make ceramic microbead blank; second step: immerse the preformed ceramic microbead blank into paraffin and organic binder The coating is carried out in a high temperature mixed solution; the coated ceramic microbeads are taken out and placed in a warm isostatic pressing equipment for isostatic pressing; after isostatic pressing, debinding and high temperature sintering are performed to obtain ceramic microbeads body; the ceramic micro-bead body after high temperature sintering is cooled to room temperature, and then placed in the fixing member for clamping and fixing; the ceramic micro-bead prepared by the present invention has the advantages of high strength, and is convenient for polishing the ceramic micro-bead .

Description

technical field [0001] The invention belongs to the technical field of grinding media, in particular to a high-strength ultrafine grinding medium and a preparation method thereof. Background technique [0002] In the mill, the energy carrier that pulverizes and grinds the material by its own impact force and grinding force is called grinding medium; the most commonly used grinding medium is ball medium and rod medium, among which, the ball medium mainly includes ceramic microbeads. [0003] In the prior art, after the preparation of ceramic microbeads, polishing treatment is required, and the traditional method is manual operation. First, the ceramic microbeads are fixed by a fixing mechanism, and then the surface of the ceramic microbeads is polished in a hand-held polishing machine. , and this kind of work has the problems of manual work, low work efficiency, and only a single ceramic microbead can be polished at a time. SUMMARY OF THE INVENTION [0004] The purpose of ...
