Abstract & Overview
In the past 20 years, with the rapid development of China's economy, China's coal preparation technology has made great progress Clean and efficient utilization of coal is the primary task to promote the green and low-carbon transformation of China's energy, and it is also an important technical way for the coal industry to achieve the goal of "double carbon" Coal washing and processing is the premise and foundation of clean and efficient utilization of coal, and it is also the only way for coal industry to transform into clean, low-carbon, safe and efficient direction. Under the influence of "double carbon" policy, coal preparation, as the source and foundation of clean utilization of coal, is facing new challenges and opportunities. This paper reviews the development status of coal preparation technology in China in recent 20 years from the aspects of coal preparation technology, coal preparation equipment and intelligent coal preparation. This paper reviews the problems and solutions in coal preparation industry, and looks forward to the future technology development trend.
