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 least energy consumption of 109 kWh/ton was ...

Coal slurry is prepared by wet grinding the coal in a rod mill. Coal is delivered by conveyor into the rod mill feed hopper. The coal has to be ground to the right particle size and size distribution in order to form a stable coal/water slurry at optimum slurry solids concentration, which is typically about 60 to 65% by weight.
