Abstract：As the pressure on coal preparation plants to process raw coal increases,the importance of efficient coal separation has become increasingly critical.Traditional coal separation equipment often suffers from limitations such as insufficient processing capacity,low separation efficiency,and poor recovery of iron impurities.To address these challenges,we developed an intelligent,self-controlled two-stage coal separation system and conducted field trials in a coal washing plant.The results demonstrate significant improvements in key performance metrics:the system increased processing capacity by 12.2%,enhanced separation efficiency by 10.6%,reduced energy consumption by 6.7%,and improved iron impurity recovery by 13.4%.This innovative system provides a cost-effective and sustainable solution for coal industry,offering a promising approach to meet the growing demands for efficient and environmentally friendly coal processing.
