Optimization of operating conditions on ultra fine coal

1 day ago This study investigated ultra fine coal grinding performance of four low to moderate cost grinding media in a laboratory stirred mill. Kinetic grinding tests showed that silica beads generated the finest product size with a P 80 of 5.9 μm from a feed size of 24.4 μm while having a specific energy SE input of 309 kWh/ton. Nonetheless the least energy consumption of 109
