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 …

Wet grinding experiments conclude that 30 min of grinding time, 350 rpm speed, water addition of 50% (w/w), and 2 mm grinding media results in achieving the fine-sized coal slurry with an average particle size of 45 μ and total undersize less than 75 μ. It was observed that direct centrifugal separation at 50% pulp density can result in ...

Grinding kinetics of −3.0 + 1.0 mm coal in wet ball-milling were investigated using the breakage rate and primary breakage distribution functions. The deceleration effect for the wet grinding of this coal sample was due to the relatively stronger material (quartz), which had a slower breakage rate compared to the weaker material (organic matter).
