Development trend of China’s coal preparation industry in critical process and equipment

Abstract

This paper gives a brief introduction about the current status of China’s coal preparation industry in the context of new environmental requirements. By analyzing the current development status of the development in coal preparation process and equipment, the paper points out the key technologies and critical equipment needs to be developed for the industry, and the breakthrough in developing the large-scale and reliable critical equipment, automation technology with independent intellectual property, perfecting coal preparation process and environment-friendly coal preparation technologies, breaking through the key technical bottleneck, enhancing core competitiveness and solving the critical problems of the industry. In addition, the paper forecasts that the future trends of coal preparation industry in China of upsizing scale, higher efficiency, intelligentization, environmental protection and cleanness. The paper also analyzes the major problems and contradictions existing in China’s coal preparation industry, and gives directions to optimize the utilization of coal resources and increase the clean and adaptation degree of coal product to steadily attain sustainable development and step into an age of “green coal preparation industry”.
