The wear-resistant alumina ball is made of selected high-quality raw materials, advanced molding technology and calcined in high-temperature tunnel kiln. The product has the characteristics of high density, high hardness, low wear, good seismic stability, corrosion resistance, etc. it is the most ideal grinding medium for glaze, blank and various mineral powder processing. Products are widely used in ceramics, cement, coatings, refractories, inorganic mineral powder and other industries.

　　Since the 1990s, the wear-resistant alumina ball industry has sprung up in China. Today, there are at least 400 such enterprises. It is worth noting that among these enterprises, only a few enterprises produce high-quality high aluminum balls, and most of them still produce medium aluminum balls. A lot of high-quality bauxite is consumed in the production process of China aluminum ball, and its actual use effect is obviously worse than that of high aluminum ball, which is not consistent with the current energy conservation and environmental protection advocated by the ceramic industry.

　　On the other hand, the increasing number of domestic alumina ball enterprises directly leads to the emergence of price war. On the contrary, typical foreign countries producing wear-resistant alumina balls have been constantly improving the technical content of their products. There are only a few enterprises that produce high-quality high aluminum balls, as well as those that can make unremitting technological upgrading.

　　Compared with foreign countries, where is the short board of domestic wear-resistant alumina ball products? In the environment of energy saving and environmental protection, what benefits can high quality high aluminum ball bring? In the era when the industry advocates the transition from "made in China" to "intelligent manufacturing in China", in order to get the answers to these questions, in addition to improving the technical content of wear-resistant alumina ball products, the more important thing is the change of thinking of producers and users.

　　Compared with foreign enterprises, domestic wear-resistant alumina ball industry with sufficient supply of raw materials, product prices can be as low as possible. This is also the obvious advantage of domestic wear-resistant alumina ball products, especially after the financial crisis, the European market also began to use Chinese products in large quantities. Due to the good cost performance, most domestic enterprises are in full load production in recent years.

　　Compared with the advantages, the gap between domestic and foreign counterparts is more obvious. The representative foreign enterprises producing alumina balls mainly include Japan's Biliang and Italy's Bitossi. Compared with these international well-known enterprises, there is still a gap in the quality of domestic wear-resistant alumina balls, and the brand influence has become a short board for the development of domestic enterprises. At present, there are not many domestic production enterprises with certain international and domestic fame. Many enterprises are mainly OEM, lack of brand awareness, and focus on "short, flat and fast". Fortunately, at present, some domestic wear-resistant alumina pebble enterprises have begun to focus on technology improvement and brand building, and enter the international market.
