Coal fracturing and heteroatom removal. Annual report

Grindability studies have been conducted in a laboratory ball mill using processed coal. Grinding times for large-size feed coal (1-3/8 to 3/8 in.) are reduced by a factor up to 10 following exposure to CO/sub 2//water. With smaller-feed coal (4 x 8 mesh), however, improvements in grindability are much smaller.
