The present invention is directed to, among other things, a grinding and impeller clip for attaching to a wheel assembly mounted for rotational motion within a grinding chamber of a coal pulverizer, wherein the clip has an arcuate cross sectional profile and a protective layer on its upper surface.

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 capacity
