  • Pulverizer Capacity is not simply “tons throughput per hour!”

    Pulverizer capacity is comprised of five major factors. These are throughput, fineness, Hardgrove grindability, moisture content and raw coal size. Therefore, throughput is only one component of pulverizer capacity. All five factors play a part. For example, when the fineness is reduced, the throughput can be increased without the pulverizer ...
