Bowl Mill Coal Pulverizer
2. The hot air is used for transportation of the recirculating coal within the mill and also for transporting the coal from the pulverizer to the furnace. As the coal is continuously reduced in size, the smaller/lighter particles are swept from the bowl by the hot air. Hot air (and cool tempering air) is provided by the primary air fans.

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).
