Introduction:Zirconia composite ball is made of special calcined alumina powder, a certain amount of zirconium powder and other raw materials. The ball mill is grinded to a certain degree of fineness, sprayed and granulated, then pressed by isostatic pressing forming machine and calcined by tunnel kiln at high temperature. Its appearance provides more choices for customers who pursue high grinding cost performance and enriches the ceramic grinding ball product line.
What is Zirconium-aluminium Composite Ball?
Zirconia composite ball is a kind of grinding ball developed in China , also called Zirconia Toughened Alumina Ball.
It is made of special calcined alumina powder, a certain amount of zirconium powder and other raw materials. The ball mill is grinded to a certain degree of fineness, sprayed and granulated, then pressed by isostatic pressing forming machine and calcined by tunnel kiln at high temperature. Its appearance provides more choices for customers who pursue high grinding cost performance and enriches the ceramic grinding ball product line.
What are the characteristics of zirconium aluminum composite ball?
1.The whiteness of the product is close to the high aluminum ball, but the price advantage is increasingly obvious.
The name of the high alumina ball comes from the high alumina content. One of the important reasons for the popularity of high alumina ball in ceramic industry is that the product has high whiteness and less pollution to abrasive materials.The price of alumina powder in China has been increasing due to the output regulated by environmental protection policies and other factors .This directly led to its main raw material for the production of high alumina ball costs further increased. Not only that, by adding a certain amount of zirconium, the zirconium aluminum composite ball not only enhances the toughness, but also has a whiteness close to that of the high aluminum ball. Therefore, compared with the more and more expensive high aluminum ball, its price advantage is more and more obvious.
2. The grinding efficiency is equal to that of medium and high alumina ball, but the product has obvious whiteness advantage.
It is understood that some businesses will feel that the price of high alumina ball is too high and choose the medium and high alumina ball with lower price. However, the whiteness of medium and high aluminum ball products also makes some businesses who want to grind blanks with whiteness requirements headache. The grinding efficiency of zirconium aluminum composite ball is equal to that of medium high aluminum ball, and its product whiteness is one level higher than that of medium high aluminum ball. Therefore, some businesses that have certain requirements for product whiteness but do not need to reach the level of high aluminum ball prefer to choose zirconium aluminum composite ball.
3. The zirconium aluminum composite ball with high cost performance has a broad market prospect at home and abroad. Now most of the companies that produce and operate zirconium aluminum composite ball are no longer limited to the domestic market, but focus on the overseas market. Although the national standards of foreign countries, especially in Europe, are high, some powerful companies can still open up the foreign market.
In addition, normally, the quality of zirconium aluminum composite ball with good density and high degree of porcelain should be better.
