Improving Coal Pulverizer Performance and Reliability

Ring-Roll Mill the rolls may rotate while the ring is stationary). Ring-Roll (Bowl-Mill) and Ball-Race Mills comprise the majority of coal pulverizers currently in service at power generating facilities. Figure 3 shows a cut-away of a Ring-Roll type coal pulverizer. In this design the grinding rolls are stationary, while the ring (or bowl,


The Millstar Power Optimiser gave the following benefits: • Mill feed cuts were prevented, resulting in a stable mill loading. • No huge power dips occurred, since any sign of the mill overloading was detected and rectified timeously. • The standard deviation of the mill load, flotation feed flow
