Answer (1 of 2): It's more and less same as the flour mill if I talk about bowl mill. This is simplest diagram of coal mill. The crushed coal (coming from primary crusher) is stored in the cylindrical shape thing known as Bunker which is exactly on top of the mill to introduce coal into the pul...

Mill power to ton of coal throughput. In general, when the mill draws more power per ton of fuel, it is an indication that finer coal is being produced. Source: Storm Technologies

Ring-Roll (Bowl-Mill) and Ball-Race Mills comprise most coal pulverizers currently in service at pulverized coal power plants. The grinding rolls are stationary in this design, while a worm gear drive rotates the ring (commonly known as the bowl). Powerful springs force the grinding rolls against the ring, providing the pressure required to ...

2.Coal pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill. The pulverized coal and air mixture is then transport to the boiler burner ...
