摘　　要：纳米材料是指结构单元尺寸介于1 nm^100 nm范围之间的材料总称,以其三大特征效应而广泛应用于医疗业、电子业、化工业等行业。超细氧化锌是一种较为常见的纳米材料,该文使用卧式振动磨的干磨法对其进行研磨,其中采用氧化锆陶瓷作为研磨介质,对不同形状、不同尺寸的研磨介质混合进行实验,分析研磨后的粒径数据,得出研磨介质的尺寸及形状对颗粒粒径的影响。实验表明,填充率一定时,研磨氧化锌与研磨介质的比重有关,研磨介质的比重越大,其冲量也越大,得到的研磨效果越好。Nano- material is the material of the structure size between 1 nm ~ 100 nm,which has been widely used in medical industry,electronic industry,chemical industry and other industries because of its three characteristic effects. Ultrafine zinc oxide is one of the most common nanomaterials. This work used a dry grinding method of horizontal vibrating mill to grind the ultrafine zinc oxide. Zirconia ceramic was used as the grinding medium. Experiment with different shape,different size of grinding medium mixing method,were carried out to analyze the data of the grinding particle size and to study the grinding medium size and shape on the influence of particle size. The results show that,when the grinding medium filling rate is constant,grinding of zinc oxide is associated with the proportion of grinding media,the proportion of grinding beads greater,the impulse greater and the grinding efficiency higher.
