How does wear-resistant alumina ball move towards intelligent manufacturing

- Jan 23, 2021-

The wear-resistant alumina ball is made of selected high-quality raw materials, advanced molding technology, and calcined in a 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 processing glazes, blanks and various mineral powders. Products are widely used in ceramics, cement, coatings, refractory materials, inorganic mineral powders and other industries.

Since the wear-resistant alumina ball industry emerged in China in the 1990s, it has developed to this day and there have been at least 400 such enterprises. It is worth noting that among such enterprises, there are only a handful of enterprises that produce high-quality high-aluminum balls, and most of them still produce medium-aluminum balls. A large amount of high-quality bauxite needs to be consumed in the production process of Chalco balls, and its actual use effect is obviously worse than that of high alumina balls. This does not seem to be in line with the energy-saving and environmental protection advocated by the ceramic industry.

On the other hand, the increase in the number of domestic alumina ball companies has directly led to the emergence of price wars. On the contrary, typical countries that produce wear-resistant alumina balls abroad have been constantly improving the technical content of their products. There are only a handful of companies that produce high-quality high-alumina balls, and there are also only a handful of companies that can consistently upgrade their technology.

Compared with foreign countries, where are the shortcomings of domestic wear-resistant alumina ball products? In the environment of energy saving and environmental protection, what benefits can high-quality high-alumina balls bring? The industry advocates the transition from "Made in China" to "Intelligent manufacturing in China" In the new era, in order to obtain the answers to these questions, in addition to improving the technical content of wear-resistant alumina ball products, more importantly, the changes in the thinking of producers and users.

Compared with foreign companies, the domestic wear-resistant alumina ball industry can keep product prices as low as possible by virtue of sufficient supply of raw materials. This is also the obvious 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 the good cost performance, most domestic enterprises have been in full production in recent years.

Compared with advantages, the gap between domestic wear-resistant alumina balls and foreign counterparts is more obvious. The representative companies producing alumina balls abroad mainly include companies such as Japan's Biliang and Italy's BITOSSI. Compared with these well-known international companies, there is still a gap in the quality of domestic wear-resistant alumina balls, and brand influence has become a shortcoming for the development of domestic enterprises. At present, there are not many domestic production companies that have a certain degree of international and domestic reputation. Many companies mainly focus on OEM, lack brand awareness, and focus on "short and fast". Fortunately, there are already some wear-resistant alumina ball stone enterprises in China that have begun to focus on technology improvement and brand building, and enter the international market.
