一般瓷球分为研磨类陶瓷球和填料陶瓷球,不同种类的陶瓷球有不同的物理化学特性,这就决定了它们在不同行业的用途。 研磨类瓷球分为碳化硅研磨瓷球、微晶中铝研磨瓷球、高铝研磨瓷球。一般来讲含铝量60%—65%划为中铝球,含铝量75%—80%为中高铝球,含铝量90%以上为高铝球。其中高铝球又细分为90瓷、92瓷、95瓷和99瓷。99瓷由于其极高的生产成本而很少有大型厂家大批量制造,目前主要为部分特种陶瓷厂通过手工制作。 主要陶瓷球种类: 1、氮化硅陶瓷球(Si3N4) 2、氧化锆陶瓷球(ZrO2) 3、碳化硅陶瓷球(SiC) 4、高纯氧化铝陶瓷球(Al2O3) 制作方法: 1、通过挤压法成型 2、通过团粒法成型 3、通过液压硬膜成型 陶瓷球成型方法常见压制球和滚制球两种。由于工艺过程的差异,导致成型、焙烧后的球石内部晶体结构不同,密实程度和抗冲击的能力也不一样,通过多次、反复的破坏性试验,我们发现:在研磨水泥物料的过程中,相同材质、相同规格的陶瓷球,压制球破损率低于滚制球。 The types and methods of making ceramic balls General ceramic ball is divided into grinding ceramic ball and packed ceramic ball, different kinds of ceramic ball have different physical and chemical properties, which determines their use in different industries. Grinding ceramic ball is divided into silicon carbide grinding ceramic ball, aluminum grinding ceramic ball in microcrystalline, high aluminum grinding ceramic ball.Generally speaking, 60%-65% of aluminum content is classified as aluminum ball, 75-80% of aluminum content is medium and high aluminum ball, and more than 90% of aluminum content is high aluminum ball.The high aluminum ball is subdivided into 90 porcelain, 92 porcelain, 95 porcelain and 99 porcelain.Due to its high production cost, 99 porcelain is rarely mass-produced by large manufacturers. At present, it is mainly made by hand in some special ceramic factories. Main types of ceramic balls: 1. Silicon Nitride Ceramic Ball (Si3N4) 2. Zirconia ceramic ball (ZrO2) 3, silicon carbide ceramic ball (SiC) 4, high purity alumina ceramic ball (Al2O3) Making method: 1, by extrusion molding 2, through the method of pellet molding 3. Forming by hydraulic hard membrane Ceramic ball molding method common press ball and roll ball two.Due to differences in technological process, after forming, roasting the ball inside the stone crystal structure, solid degree and impact resistant ability is different also, through multiple, repeated destructive test, we found that: in the process of grinding material of cement, ceramic balls of the same material, same specification, suppress breakage rate is lower than the ball rolled the ball.
