Since the first application using an MPS mill to process pulverized coal in Germany in the mid 1960s, there have been over 2,000 different MPS mill installations operating in coal-fired power plants worldwide. As one of the most popular coal pulverizers in the utility industry, the MPS mill was first introduced into the US in the early 1970s.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 ...
