Application Of Wear-resistant Ceramics in Coal Industry

2021-12-14
Latest company news about Application Of Wear-resistant Ceramics in Coal Industry

Coal preparation is an important process in the comprehensive utilization of coal mine resources. Many metal and non-metal parts in coal preparation equipment will suffer strong wear and quickly fail due to continuous work, resulting in a large amount of human and financial consumption, and at the same time they are unable to Meet the continuous production needs of coal preparation plants. The serious wear and tear of coal preparation equipment and the low service life have become a serious obstacle to the development of coal preparation plants. Therefore, given the unique working conditions of coal preparation equipment, it is of great significance to reasonably research and develop new wear-resistant materials to extend the service life of coal preparation equipment.

Wear-resistant ceramic sheets are an important technical means to improve the reliability of various equipment in coal preparation plants. Among the traditional wear-resistant materials, ceramic materials have become the most common and important type of materials in human life due to their wide sources and superior material properties. They are characterized by high hardness, wear resistance, and corrosion resistance. The wear-resistant ceramic sheet with alumina as the main component has become the most widely used material for its simple process, low processing cost, and good wear resistance. At present, it has been widely used in metallurgy, mining, and chemical industries.

 

At present, wear-resistant ceramic sheets are widely used in cyclones, chutes, and pipelines in coal preparation plants. The wear resistance of wear-resistant ceramic sheets mainly depends on three aspects, namely, formula, raw material powder and sintering process. From the perspective of the development status of wear-resistant materials and the needs of the coal preparation market, expensive materials such as silicon carbide cannot be used in the coal preparation field on a large scale. Reasonable cost performance of materials, alumina wear-resistant ceramics will be the key research direction of wear-resistant materials.
