Alumina Grinding Ball
1)Alumina grinding Ceramic Ball is one ideal ball mill grinding media, it can keep the purity and improve the stability of grinded materials.
2)The alumina grinding ball have been widely used in ball mills as abrasive media for ceramic raw materials and glaze materials in ceramic factories, cement factories, enamel factories and glasswork.
3)The main features are high density, high hardness and strength, high wear resistance, thermal stability, corrosion resistance and non-pollution etc.
4)During the abrasive/grinding processes, ceramic balls will not be broken, it will not contaminate the materials to be grinded.
5)Type: According to the content of aluminum oxide: 60-70%, 65-75%, 95%, 95%

Recently, the China Automobile Industry Association organized a mid-term review meeting of the “China Auto Parts Industry Development Strategy†subproject of the “China Automobile Development Strategy†jointly undertaken by FAW, SAIC, Dongfeng, GAC and other domestic top 10 vehicle companies in Beijing. .
The Guangzhou Institute of Mechanical Science participated in the judging panel as a member of the research group. At the meeting, the research group reported to the participating experts on the phased research results of the sub-topic "China's auto parts industry development strategy." The experts attending the meeting highly appraised the research results of the research group, fully affirmed the task force, had sufficient preparations in the early stage, accurate strategic positioning, and clear target positioning. At the same time, the participating experts also provided valuable suggestions and opinions on the next step of the task force.

As the basis of the automotive industry, auto parts and components are necessary factors to support the sustained and healthy development of the auto industry. In particular, the current auto industry is vigorously developing and innovating in full swing. It also requires a strong component system as a support. The independent brands and technological innovation of the vehicle require components as the basis, and the independent innovation of parts and components has a strong impetus to the development of the entire vehicle industry. They are mutual influence and interactions, there is no independent brand of the whole vehicle, and the powerful component system The ability to develop and innovate is difficult to burst, and there is no strong component system to support.
Domestic parts are mainly used for self-owned brand passenger vehicles and commercial vehicles, with low market share. According to data from the Ministry of Commerce, foreign capital controls most of the market share of auto parts, and domestic sales of parts and components only account for 20% of the whole industry. -25% of auto parts manufacturers with foreign backgrounds account for more than 75% of the entire industry. Of these foreign suppliers, 55% are wholly-owned companies, 45% are Chinese-foreign joint ventures, and local parts are mainly used in auto brands. Market share is low. In the areas of high-tech content such as automotive electronics and engine parts, the foreign market share is as high as 90%. Among them, the output of key components such as automotive EFI systems, engine management systems, ABS and airbags, and automatic transmissions, etc. The proportions are 100%, 100% and 91%, respectively, and 69%.
