Construction of dry and wet combined multi-particle fractionation system
Coal is the main energy source in China,and the development and utilization of low rank coal,as an important part of China's coal reserves,has attracted much attention.In this paper,the application effect of the dry-wet combined multi-grain sorting system for low-rank coal is analyzed with the Harsusu Coal Processing Plant as the research object.By combining the low rank power coal depth screening and classification technology,the process parameter-based density prediction and regulation technology of heavy media sorting,and the high-density level dry sorting technology,the raw coal into the washing ratio of the Halwusu Coal Preparation Plant was increased by 14.41 percentage points,the refined coal yield was improved by 9.88 percentage points,and the calorific value of the commercial coal was increased by 113 kcal/kg.The study shows that this dry and wet combined sorting process provides a good opportunity for the The study shows that this dry-wet combined sorting process provides an effective solution for the quality improvement and utilization of low-rank coal.
