Whether from a plant survey or torque-mill test, the calculation method of the mill energy specific cumulative grinding rates is shown by the following example. Using plant data, the value of E is the specific energy input to the solid material as it passes through the plant mill (the mill power draw divided by the mill solids throughput rate ...
The power consumed by the mill per ton of coal ground is only two-thirds of the ball mills. However if the primary air fan power is also taken into account, in the case of a pressurized mill the power consumption is lower only by about 15%.
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).
