The point we are trying to make is this: coal pulverizer capacity is a specified fuel grinding capability or throughput at a certain HGI (coal grindability index) and also based on raw coal size, moisture and desired fineness level. These factors are significant and must all be taken into account when discussions of pulverizer capacity become serious. We have written volumes .
