“…Recently, some researchers also studied the non-mechanical liberation of coal. [13][14][15][16] They use methods like electrical disintegration, high-voltage pulses or microwave pretreatment. The results of these studies indicated that the liberation of coal and ore by non-mechanical means generated a higher percentage of valuable components and lower percentage of fine material than mechanical liberation.…”

Effect of Grinding Behavior on Liberation of Coal Macerals

et al. 2022

Macerals are the smallest organic constituents of coal. Reactive macerals or vitrinite is mainly responsible for coking potential of a coal during carbonization method. The effect of a novel grinding on coal maceral separation is studied in this work. The alternate method is based on grinding of coals by shearing compared to impact crushing as in other conventional methods like hammer mill. It is found that liberation of vitrinite is better in shearing. Coking properties of such maceral enriched coals showed improvement in laboratory coke making tests.
