The capacity in lbs./hr. of the mill Is calculated on the assumption that the coal hardness is 55 on the hardgrove. Grindability index and has a moisture content of 8%. This would then produce an output based on 70% of the coal passing thru a 200 mesh screen. Mills are capable of grinding harder coal with higher
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 ...
