Present status and developing trend of China′s power coal cleaning technology

Following an introduction to the characteristics of traditional power coal cleaning processes applied in China, an analysis is made of the technical features of the new technologies that have been in widespread use in recent years, such as the dry deep screening and TDS intelligent dry cleaning processes. Finally, it is proposed that realization of maximized overall economic benefits, reliable control of product quality and minimized operating cost is the basic principle that needs to be followed in process design.
