The invention belongs to the technical field of ceramic microsphere production, and particularly relates to ceramic microspheres for grinding and a preparation method and device thereof. Comprising the following steps: taking yttrium-stabilized nano zirconium oxide as a raw material, adding 0.5-1.5% by mass of rare earth oxide and 1-3% by mass of magnesium oxide, putting into a ball mill for mixing, and then putting into a closed stirring granulator; spraying and adding an aqueous solution containing 1% of PVA into the powder by using an atomization spraying device, and granulating; the prepared spherical particles are subjected to sphericity degree and particle size sorting through a sorting machine; and sintering the sorted microsphere blanks in an air environment of 1500-1600 DEG C to obtain the ceramic microspheres for grinding. The preparation method is short in time consumption and high in production efficiency, and through the combined action of magnesium oxide and rare earth oxide, the interior of the ball blank is compact, and the strength is high.
本发明属于陶瓷微球生产技术领域，具体涉及研磨用陶瓷微球及其制备方法和装置。包括以下步骤：以钇稳定纳米氧化锆为原料，添加其质量分数为0.5～1.5％的稀土氧化物和1％～3％氧化镁，投入到球磨机中混合，之后投入封闭式搅拌制粒机中；利用雾化喷淋装置将含有1％PVA水溶液喷洒添加到粉料中制粒；将制得的球状颗粒通过分选机进行球形度和颗粒大小分选；分选后的微球坯体在1500～1600℃空气环境中进行烧结，即得研磨用陶瓷微球。本制备方法用时短，生产效率高，通过氧化镁和稀土氧化物的共同作用，使得球坯内部致密，强度高。
