Wear resistant alumina balls are made from carefully selected high-quality raw materials and advanced molding technology, and are calcined in high-temperature tunnel kilns. The product has the characteristics of high density, high hardness, low wear, good seismic stability, and corrosion resistance, making it the most ideal grinding medium for processing glazes, blanks, and various mineral powders. The product is widely used in industries such as ceramics, cement, coatings, refractory materials, and inorganic mineral powders.

Since the rise of the wear-resistant alumina ball industry in China in the 1990s, at least 400 such enterprises have emerged today. It is worth noting that among these types of enterprises, there are only a few that produce high-quality high aluminum balls, and most enterprises still focus on producing medium aluminum balls. The production process of medium alumina balls requires a large amount of high-quality bauxite, and its actual use effect is significantly worse than that of high alumina balls, which seems to be inconsistent with the current promotion of energy conservation and environmental protection in the ceramic industry.
On the other hand, the increasing number of domestic alumina ball enterprises has directly led to the emergence of price wars. On the contrary, typical countries producing wear-resistant alumina balls abroad have been continuously improving the technological content of their products. There are only a few enterprises that produce high-quality aluminum balls, and there are also few enterprises that can persistently upgrade their technology.
What are the shortcomings of domestic wear-resistant alumina ball products compared to foreign countries? What benefits can high-quality aluminum balls bring in the context of energy conservation and environmental protection? In the era of promoting the transition from "Made in China" to "Intelligent Manufacturing in China" in the industry, in order to obtain answers to these questions, in addition to improving the technological content of wear-resistant alumina ball products, it is more important to shift the thinking of producers and users.
Compared with foreign enterprises, the domestic wear-resistant alumina ball industry can keep product prices as low as possible with sufficient raw material supply. This is also a clear advantage of domestic wear-resistant alumina ball products, especially after the financial crisis, the European market has also begun to use Chinese products in large quantities. Due to their good cost-effectiveness, most domestic enterprises have been operating at full capacity in recent years.
Compared with its advantages, the gap between domestic wear-resistant alumina balls and their foreign counterparts is more obvious. The representative enterprises producing alumina balls abroad mainly include companies such as Japan's Bi Liang and Italy's BITOSSI. Compared with these internationally renowned enterprises, there is still a gap in the quality of domestically produced wear-resistant alumina balls, and brand influence has become a shortcoming in the development of domestic enterprises. At present, there are not many domestic production enterprises with certain international and domestic reputation. Many enterprises mainly rely on OEM and lack brand awareness, focusing on "short, flat and fast". Fortunately, some wear-resistant alumina ball stone enterprises in China have started to focus on technological improvement and brand building, and have entered the international market.
