Description
0.5-90mm Alumina Ceramic Grinding Media balls has suitable hardness, moderate density and wear resistance. Corrosion resistance and low price, so most of the raw materials for building sanitary ceramics are processed with alumina ball milling media.
The alumina grinding ball is made of high-purity alumina powder by rolling or isostatic pressing, and then sintered at high temperature. 92 The density of alumina ball is about 3.6, the Mohs hardness is 9, the water absorption is about 0.01%, and the self wear amount is 0.01.
The production method of alumina ball
Alumina powder is rolled with a ball machine, or sintered at high temperature after isostatic pressing.
Types of alumina balls
According to the content of alumina, it can be divided into 92 alumina balls, 95 alumina balls, 99 alumina balls.
Feature
Taking the high aluminum ball with 92% content as an example, its specific gravity (density) should reach more than 3.60, the alumina content should reach more than 91.5%, and the iron content is low. The same raw material, the same formula, and the same firing temperature, the smaller the fineness of the powder after the raw material is ground, the higher the specific gravity and the better the wear resistance.
Application
In the grinding industry, alumina balls have won a wide range of markets due to their high hardness and high cost performance, and alumina balls are also widely used in the manufacture of luminescent materials, semiconductor electronic packaging, lithium batteries, catalysts, protective coatings, Grinding and polishing, ceramic materials, cement powder, etc.
