Grinding kinetics of −3.0 + 1.0 mm coal in wet ball-milling were investigated using the breakage rate and primary breakage distribution functions. The deceleration effect for the wet grinding of this coal sample was due to the relatively stronger material (quartz), which had a slower breakage rate compared to the weaker material (organic matter).
