As the fastest developing country in the economic development, China's market potential has attracted worldwide attention in the past 20 years, and China's grinding technology is also developing rapidly. Taking cement enterprises as an example, according to incomplete statistics, there were 2,073 cement grinding enterprises in 2010, 1,323 new dry-process cement production lines, 920 million tons of grinding capacity, and 610 million tons of output, accounting for 32.6% of cement production. The grinding capacity was 66.3%; the annual grinding of physical coal was 185.26 million tons, the grinding raw material was 1.95 billion tons, and the grinding cement was 1.88 billion tons.
In terms of power supply, there are more than 500 thermal power plants in China. Among them, medium-speed coal mills account for more than 50% of the coal-powder preparation systems, and 2000 sets of vertical coal mills run nationwide. Milling tons of pulverized coal.
In these grinding systems, whether it is a traditional tube mill, or a grinding system such as a vertical mill or a roller press, the wear parts must have anti-wear properties compatible with the system. Hard surface surfacing technology has developed rapidly with the rapid growth of anti-wear requirements in various industries, and has become one of the most economically viable methods for surface hardening of metal wear resistant materials. This provides a very large space for the development of surfacing and wear-resistant technology, and at the same time, the requirements for wear-resistant technology are getting higher and higher.
