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 …

Autogenous grinding mechanism is proposed in this paper to have a grinding where the grinding media is itself. In this process, the harder fraction of coal is not grinded and this will enhance the breakage through grain boundaries due to bond strength [22, 23].Autogenous mills have other advantages like, output of a unit volume …
