    B. Miller, in Ultra-Supercritical Coal Power Plants, 2013 Grindability. Pulverizer systems, which integrate drying, grinding, classification, and transport of the ground fuel to the burners, can present the greatest problems when switching coals/fuels (Carpenter, 1998).Low quality fuels may have grinding properties that are markedly different from the pulverizer design coal (Kitto and Stultz

    Coal grinding to obtain water-coal fuel

    First, we ground “dry” the coal of 10–15 mm fraction using AVS-150 vortex layer device for two minutes. Coal grinding was checked by means of testing sieves. 96% of coal passed through a 316 m sieve. Next, the sifted sample was run through a 160 m sieve with a 60% result obtained. And 10% of the sample was run through a 50 m sieve
