(b) COAL FINENESS Low volatile matter coals need to be ground finer. The rule of thumb is that the R90 um target should be half of the volatile matter content which in your case means you would have to grind the anthracite to 3.5 on 90um sieve. (In addition a special burner tip design is often needed for anthracite coal.)
