The difference between alumina balls and filled alumina ceramic balls
The difference between alumina balls and filled alumina ceramic balls is that there are many kinds of them in the industry, which can be divided into alumina grinding balls and activated alumina ceramic material balls. Today we will discuss their differences.
First of all, from the appearance, it is difficult for us to distinguish with the naked eye which is filled with alumina balls and alumina ceramic material balls, because the appearance is white spherical, and it is easy to distinguish by hand. The surface of the alumina grinding ball is very smooth to the touch, and the outer surface of the alumina ceramic ball is also rough to the touch.
It can also be distinguished by the outer diameter of the ball. The balling process of alumina grinding balls with a ball diameter greater than or equal to 30 is isostatic pressing, that is, the ball is pressed, and there are obvious pressure lines on the surface, so we can easily distinguish the balls with a diameter greater than 30 from the appearance. The alumina content of alumina balls is different from that of other ceramic balls. The content of alumina grinding balls is 92 porcelain and 95 porcelain, and the inert alumina fillers are 92 porcelain, 95 porcelain and 99 porcelain. There is also a big difference between the two in use. Alumina balls are mainly used in the grinding industry, and are widely used in ceramic industry, cement industry, paint industry, refractory materials and other industries. Inert alumina packing balls are used as tower packing balls, catalyst supports, petrochemical plants, chemical fiber plants and alkylbenzenes in the petroleum and chemical industries by chemical reactions. Ethylene plants, natural gas plants, etc. A hydromolecular refining unit and a demethylation unit are added as bottom fillers.
