Alumina Ceramic Grinding Balls - 95% Wear-Resistant Ceramic Balls
Alumina ceramic grinding balls are a non-metallic grinding media widely used in industrial grinding. It has many physical and chemical advantages that are different from metal grinding balls. Alumina ceramic grinding balls are made of high-purity alumina powder through isostatic pressing and high-temperature sintering. The density of 92 alumina balls is around 3.6, the Mohs hardness is level 9, the water absorption is close to 0, and the self-wear is 0.01%.
95% Wear-Resistant Ceramic Ball - the Difference Between "Balls"
Wear-resistant ceramic balls (alumina) are now commonly used in two types: 92% and 95%. For some abrasives that are special and require high alumina content, it is recommended to use 95% wear-resistant ceramic balls.
The problem that various companies face when purchasing today is that the quality of wear-resistant ceramic ball products is uneven, and the prices are also different. Therefore, for purchasing, it is not easy to buy products with good quality and reasonable prices.
Among the important indicators of wear-resistant ceramic balls are wear and content. Now many companies can do it with a content of 95%, so this is not a big problem. Then the problem comes. Many purchasing personnel do not have a deep understanding of balls. As long as the content and use of the information they obtain meet the requirements, the rest is just price comparison. In fact, it is not the case. The level of wear has a great impact on the price. If you buy it back just because of the price, it is very likely that the ball you bought does not meet the standard due to wear, and the grinding slag of the wear-resistant ceramic ball is mixed in, which affects the quality of the abrasive. Of course, the more obvious result of low wear is that it does not withstand use and increases the purchase cost again.
The reason for purchasing carefully is to pay attention to cost performance. The main difference between wear-resistant ceramic balls is that the wear is different. Different raw materials for the production of wear-resistant ceramic balls lead to huge differences in their final performance. Everyone in the know understands that the market is divided into three categories: low, medium, and high. What's the difference? Raw materials, formulations, and processes. For the same formula and process, the raw materials may be pure alumina powder or a mixture of alumina powder and bauxite. The resulting ball will definitely have different abrasion. The wear-resistant ceramic balls made of pure alumina powder have much lower wear than those mixed with bauxite. Of course, because the price of alumina powder has been rising in recent years, the price of the finished product is also higher than that of ordinary ball stones.
It is recommended that various industries choose different balls according to their own product working conditions. For example, if the hardness of the grinding material is not high and the quality of the product is not very stringent, you can choose ordinary ball stones. For example, for metal ores, it is better to use low-wear ball stones.
Application of Alumina Ceramic Grinding Balls
It is precisely because of the above characteristics that alumina ceramic grinding balls are widely used in fine grinding in various industries. These include the following aspects.
Glass grinding. First of all, the hardness of glass is very high, and ordinary grinding media has limited processing capabilities. The mixing of too many impurities will greatly reduce the quality of the glass. As a result, the finished glass is of poor quality and cannot produce high-quality products. Alumina grinding balls can solve this problem very well.
Quartz grinding. Similarly, the hardness of quartz is also very high, especially high-white quartz, which has high requirements for whiteness. Alumina happens to be white in color, which solves the grinding problem of high-white quartz in many aspects.
Cement grinding. This is an industry that has been very popular in recent years. Alumina ceramic grinding balls have extremely low wear, thermal conductivity, and low density. It performs very well in the second-stage grinding of water mills, saving energy and consumption, and improving product quality. But its disadvantage is that it has a brittle texture and is easily broken. Therefore, the transformation of this industry requires a professional technical team.
Lithium battery grinding. This is an emerging sunrise industry, and the reason why alumina ceramic grinding balls can show their great power in it is due to its own material. We know that lithium battery materials are very sensitive to iron, so metal grinding cannot be used in them. As for non-metallic grinding media, alumina grinding ceramic balls have the highest efficiency, so they have become the most popular grinding material.
