一般瓷球分為研磨類(lèi)陶瓷球和填料陶瓷球,不同種類(lèi)的陶瓷球有不同的物理化學(xué)特性,這就決定了它們?cè)诓煌袠I(yè)的用途。 研磨類(lèi)瓷球分為碳化硅研磨瓷球、微晶中鋁研磨瓷球、高鋁研磨瓷球。一般來(lái)講含鋁量60%—65%劃為中鋁球,含鋁量75%—80%為中高鋁球,含鋁量90%以上為高鋁球。其中高鋁球又細(xì)分為90瓷、92瓷、95瓷和99瓷。99瓷由于其極高的生產(chǎn)成本而很少有大型廠家大批量制造,目前主要為部分特種陶瓷廠通過(guò)手工制作。 主要陶瓷球種類(lèi): 1、氮化硅陶瓷球(Si3N4) 2、氧化鋯陶瓷球(ZrO2) 3、碳化硅陶瓷球(SiC) 4、高純氧化鋁陶瓷球(Al2O3) 制作方法: 1、通過(guò)擠壓法成型 2、通過(guò)團(tuán)粒法成型 3、通過(guò)液壓硬膜成型 陶瓷球成型方法常見(jiàn)壓制球和滾制球兩種。由于工藝過(guò)程的差異,導(dǎo)致成型、焙燒后的球石內(nèi)部晶體結(jié)構(gòu)不同,密實(shí)程度和抗沖擊的能力也不一樣,通過(guò)多次、反復(fù)的破壞性試驗(yàn),我們發(fā)現(xiàn):在研磨水泥物料的過(guò)程中,相同材質(zhì)、相同規(guī)格的陶瓷球,壓制球破損率低于滾制球。 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.
