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 ...

The kwhr/ton requirement in pulverization which has no correction for differences in fineness produced, ranged from 23.3 to 29.3 for the ball mill and from 23.0 to 38.0 kwhr/ton for the hammermill. Pulverization of the lignite from the Indianhead mine in the hammermill is again the exception; this required 46.0 kwhr/ton.

SAG mill vs Ball mill Crushing ratio. The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach ...
