Process introduction The coal mill can be divided into low speed coal mill medium speed coal mill and high speed coal mill. These three kinds of coal mills have their own good points customers can choose each one suitable for production according to the actual demands.
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.
