Wet Ball Mill
The wet ball mill has two types as follow: grid type and overflow type.The grain size limit of the grinding mill is usually 0.2 ~ 0.3mm, so it is commonly used in the first segment. The particle size of the grinding mill is generally less than 0.2mm, so it is suitable for the second grinding of the middle product in the two-stage grinding process.

Ball Mill (Ball Mills Explained)
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Grinding kinetics of coal in wet ball-milling using the Taguchi method
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).
