When impact mills are used, vitrinite maceral grains tend to shatter more and are therefore less involved in cokemaking. To address this issue, a new crushing machine based on a shear fracture mechanism, termed as coal shear crusher (CSC), was developed (Meshram et al., 2022). When compared to the hammer mill, the CSCprocessed coal showed ...
