Grindability an overview ScienceDirect Topics

The grindability of coal, or the ease with which it may be ground fine enough for use as a pulverized fuel, is of considerable practical importance. It is a composite physical property usually evaluated by empirical tests; the Hardgrove grindability procedure and index (ASTM D409, ISO 5074) is commonly used.

Emergency inerting systems for coal-grinding applications

2011-10-21  In the case of coal-grinding or storage (as one might find in a cement plant) it is not possible to remove the fuel (coal) or ignition source (grinding energy, heat, static charges) and so one has to concentrate on removing the third necessary component O 2. This fact has given rise to inerting systems that rely on the use of inert gases.
