TL;DRAbstract
The tribocharging relation between mineral components in coal and stainless steel and the effect of the environment humidity and friction time on electrification are researched and analyzed in this paper. Tests were conducted in both bench-scale and pilot system based on basic study. Test results demonstrated the feasibility of deep removal of ash and pyrite from fine coal. Scale-up design of the system was successful.
