Coal dried with air at 250350°C for milling in low, medium or highspeed 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.
WhatsApp: +86 1820369537720. Fineness is an indicator of the quality of the pulverizer action. Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indicates optimum mill performance. The mill wear and the power consumption are increased if the 70% ...
