MPS-89 pulverizers are rated for about 125,000 pounds of coal per hour and this is often referred to as the mill capacity. We prefer to discuss coal throughput as one of the three major components of capacity (Hardgrove grindability and fineness are the other two). Take one version of a typical correction curve for a pulverizer rated at 125,000

5. Lower air flow can result in more pyrites, but fewer burner eyebrows. 6. Lower air flow means and a greater tendency to plug with wet coal. 7. Lower air flow leaves more reserve fines in the pulverizer. 8. Also note that lower air flow leaves a deeper bed depth of coal, and thus a …
