The crushed coal is then transported to the store yard. Coal is transported to bowl mills by coal feeders. 3. Bowl Mill. The coal is pulverized in the bowl mill, where it is grounded to a powder form. The mill consists of a round metallic table on which coal particles fall. This table is rotated with the help of a motor.
