This study investigated ultrafine coal grinding performance of four low to moderatecost grinding media in a laboratory stirred mill. Kinetic grinding tests showed that silica beads generated the finest product size with a P 80 of μm from a feed size of μm while having a specific energy (SE) input of 309 kWh/ton. Nonetheless, the ...
The mill receives coal feed and grinds it by the impact and friction of rolling balls. For grinding coal, ball mills are frequently used in cement factories and coalfired power plants. Vertical Roller Mills (VRM): To grind coal between the rollers and a fixed grinding surface, VRMs use vertical rollers that revolve around their own axes. The ...
