Description
技术领域
本发明属于无机非金属材料(陶瓷)领域,涉及一种高性能高铝陶瓷研磨球及其制备方法。
背景技术
球磨机是物料被破碎之后,再进行粉碎的关键设备。它广泛应用于水泥、硅酸盐制品、新型建筑材料、耐火材料、化肥、黑色金属选矿以及玻璃陶瓷等生产行业,可对各种矿石和其它可磨性物料进行干式或湿式粉磨。它一般是通过研磨介质之间的挤压、撞击、剪切、研磨等达到细化物料的目的。研磨介质主要有:鹅卵石等天然研磨介质;玻璃球、陶瓷球、钢球等人造研磨介质。
近年来随着工业不断发展,对各粉料的使用量不断加大;随着技术的不断革新,对粉料的细化要求也不断升高,从而对球磨机研磨效率及研磨介质的质量要求不断升高。天然研磨介质已不能满足生产使用,人造研磨介质因为机械性能优良而广受欢迎,其中以陶瓷球耐磨性能最好。目前市场上主要销售的陶瓷球主要分为:氧化铝球、氧化锆球、碳化硅、氮化硅球等系列,又以氧化铝球和氧化锆球最为普遍。氧化锆球密度高、强度大、韧性好、耐磨性能好,被广泛应用于砂磨机等高转速的研磨机内;但因其价格较高并未在研磨行业得到普及。氧化铝球因其合适的密度、硬度、耐磨性能、高耐腐蚀性、适中的价格在球磨机、搅拌磨等中低转速的研磨机内得到广泛使用。目前市面上的氧化铝球大部分为92氧化铝球,与氧化锆球相比强度低、磨耗高,从而限制了其在砂磨机等高转速研磨机内的使用。所以,生产出一种高耐磨性、高强度、生产成本低、满足砂磨机等的研磨球正是当务之急。
发明内容
为了克服上述现有技术的不足,本发明提供了一种高性能高铝陶瓷研磨球,提高了氧化铝球的强度、降低磨耗,可以满足砂磨机等高转速研磨机的使用要求。
同时,本发明还提供了上述高性能高铝陶瓷研磨球的制备方法,公开一种新的制球方式,对于所有滚制成型的球都适用,解决现有滚制成型的陶瓷球强度普遍较低的问题。
本发明技术方案如下:
一种高性能高铝陶瓷研磨球,原料按重量百分比组成为:84-93%氧化铝,4-12%二氧化硅,1.8-2.5%轻质碳酸钙,0.25-0.6%氧化镁,0.03-0.05%二氧化钛。
优选地,所述高性能高铝陶瓷研磨球,进一步添加辅助原料聚丙烯酸铵,所述的聚丙烯酸铵加入量为上述原料总质量的1.0- 5.0%。
优选地,所述氧化铝为细晶氧化铝;所述的细晶氧化铝,其晶粒尺寸小于1.5μm,优选0.6-1.0μm。
优选地,所述高性能高铝陶瓷研磨球,晶粒粒径为1.0-1.5μm。
一种高性能高铝陶瓷研磨球的制备方法,步骤包括:
1)按配比称取各原料,放入球磨机中湿磨,用离心式喷干塔喷干为喷干粉,然后喷干粉经振动筛选取粒径为180-200目的喷干粉为种子;
进一步地,步骤1)中,湿磨至粒径为中位径尺寸0.3-0.6μm。
2)步骤1)筛余后的喷干粉用棒销式破碎机打碎,过电磁除铁机除铁后得粉料;向滚球机中加入步骤1)筛取的种子,喷水后,加入粉料,粉料包裹种子,滚制长球,得生坯球;
进一步地,步骤2)中,用棒销式破碎机打碎两次,然后过200目筛;
3)步骤2)的生坯球经抛光、干燥,之后温度不超过1380℃窑烧,得高性能高铝陶瓷研磨球。
进一步地,步骤3)中,所述的抛光时间为2-4h。
进一步地,步骤3)中,所述的干燥为24-36h的常温阴干或者是16-24h的窑尾余热风干燥;水分降至0.5%后干燥结束。
进一步地,步骤3)中,所述的窑烧,温度为1320~1380℃,优选采用辊道窑。
与现有技术相比,本发明的有益效果:配方简单、原料丰富、价格低廉、生产成本低。通过原料配比调整,利用烧成过程中各原料之间的高温反应,形成一定的液相,可以实现不超过1380℃的低温烧结;采用细晶氧化铝作为原料,使烧成的研磨球晶粒细小;从而大大地提高其耐磨性等机械性能,磨耗可以达到市面上其他氧化铝研磨球的1/10。
本发明选用筛分后的喷干粉起种子,统一种子尺寸,成球过程中球径尺寸一致,有效避免了大球挤压小球造成的尾巴球、球消失、球形状椭圆等情况。由破碎后的细粉包裹种子长球,有效提高了种子的强度,并消除普通滚制球中心强度低的问题。经本发明方法滚制而成的球强度是市面上其他同种类氧化铝球的1.5-2倍,并已实现砂磨机(转速2600r/min)运行3h后无破损,可满足砂磨机使用。

1.称取700g陶瓷球,烘箱调温到110℃,烘干至恒重。放入干燥器中冷却后用分析天平称重,记为M1,将球放入球磨罐中。
2.向球磨罐中加入300ml蒸馏水。
3.球磨罐放入快速磨中,快速磨转速500rpm。
4.研磨时间1h。
5.研磨完成后将球洗净,烘箱调温到110℃,烘干至恒重。放入干燥器中冷却后用分析天平称重,记为M2。
6.磨耗计算公式为:
(M1-M2)/M1*100%
㈡加磨料磨耗测试方法:
1.称取700g左右陶瓷球,烘箱调温到110℃,烘干至恒重。放入干燥器中冷却后用分析天平称重,记为M1,放入球磨罐中。
2.向球磨罐中加入300ml蒸馏水,加入6g分散剂。
3.向球磨罐中加入300g磨料。
4.球磨罐放入快速磨中,快速磨转速500rpm。
5.研磨时间1h。
6.研磨完成后将球洗净,烘箱调温到110℃,烘干至恒重。放入干燥器中冷却后用分析天平称重,记为M2。
7.磨耗计算公式为:
(M1-M2)/M1*100%
