The Storm Approach to Coal Pulverizer Optimization

Let's use an MPS-89 pulverizer as an example. Most 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
