The Effect Of The Mode Of Applied Breakage On Coal Yield

Attrition breakage additional to impact breakage, i.e. impact breakage followed by attritioning, to a top size of 6.7 mm resulted in an even further increase in the coal yield. This is because impact breakage to a smaller top size of 6.7 mm exposed more coal macerals than breakage to a top size of 13.2 mm. Exposed coal macerals were then ...
