Pulverised Coal - an overview | ScienceDirect Topics
Coal dried with air at 250–350°C for milling in low-, medium- or high-speed mills. Main milling costs are power and replacement of worn parts. Wear depends on fineness of grinding, and on hardness and abrasiveness of coal. Coal and air distribution to burners must be uniform to avoid local reducing zones which encourage slagging.
