Description

陶瓷研磨体及其制备方法
技术领域
本发明涉及一种适合于干法球磨工艺的陶瓷研磨体，本发明还涉及该研磨体的制备方法。
背景技术
陶瓷、水泥、火电、冶金、矿山等行业在生产之前需要用球磨机磨粉，目前，在干磨工艺中，大都采用钢球和钢锻作为研磨体，能耗高，耐磨性差，且在使用过程中，铁质物质容易进入原材料中，对产品品质造成影响。
在湿磨工艺中已有采用陶瓷研磨体来代替钢球和钢锻来研磨陶瓷类原料，现有的陶瓷研磨体其抗冲击性能差，用于干磨工艺容易碎裂，不能满足使用要求。因此，开发一种抗冲击性能好的，能适合干磨工艺中的陶瓷研磨体成为我们急需要解决的问题。
发明内容
本发明的目的就在于提供一种耐磨性好、抗冲击性能好的陶瓷研磨体，主要用于干磨工艺中，本发明还涉及该种陶瓷研磨体的制备方法。
为达到上述目的，本发明是这样实现的：一种陶瓷研磨体，其特征在于：由重量份数的以下原材料制成：
铝矾土60-90份，粘土5-20份，石墨粉3-15份。
在上述方案中：所述粘土中Al2O3的含量≥22％。
本发明的第二目的是这样实现的：一种权利要求1或2所述陶瓷研磨体的制备方法，其特征在于：按照如下方法制备：
将所述铝矾土、粘土和石墨粉混合，球磨至粒径≥300目，然后加水练泥,喷雾造粒后烘干，成型，再在1200-1500℃下烧结16-32h得到产品。
在上述方案中：烘干的温度为200-300℃。
采用上述方案，铝矾土的主要成分为Al2O3和Fe2O3，粘土的主要成分为SiO2、Al2O3、TiO2和Fe2O3，粘土和铝矾土与石墨粉混合烧结，烧结时，在产品中生成碳化硅和碳化钛，碳化硅热膨胀系数小，耐磨性好，弹性模量大，硬度高，抗弯强度大，有助于增加研磨体的硬度、致密性和抗裂性。碳化钛有利于增加研磨体的韧性，改变陶瓷研磨体的晶形结构，本发明得到的陶瓷研磨体维氏硬度大于1800，抗弯曲强度大于320Mpa，断裂韧性大于5.0Mpa，用于干磨工艺中不易碎裂。
本发明的有益效果是：本发明制得的陶瓷研磨体弹性模量大，耐磨性好、抗冲击性好，韧性好、化学稳定性好，研磨效率高，适合在干磨工艺中使用。且本发明用于陶瓷原材料、水泥、火电、冶金和矿山中，对这些原材料的污染少，制造成本低。
