the fineness is reduced from about 75% passing 200 mesh to 45% passing 200 mesh, as much as 30% more coal throughput can be pushed through the pulverizers. The previous example is often inadvertently done by increasing primary airflows or opening classifier blades up to increase the coal flow to the furnace by sacrificing coal fineness.

RETSCH's XRDMill McCrone has been used for decades for the preparation of samples prior to XRD analysis. The unique grinding principle helps to preserve the crystal lattice of the sample much better than other mills, for example ball mills. Table 1.

Coal Mill Fineness Analysis. Every coal mill is designed with a particular fuel grinding capacity or throughput at a certain Hardgrove grindability index (HGI), based on a defined raw coal size, moisture content, and desired fineness level.
