Coal Grinding Cement Plant Optimization

Drying and grinding are generally being done in either air swept ball mill or a vertical mill. The selection of mill system will depend mostly on the factors like initial capital cost, drying and grinding capacity required, cost of energy power etc. Coal Fineness It is understood generally that the finer we grind, the easy it is for burning. However, the fineness required will always be directed by where to fire and what type of coal

Pulverised Coal An Overview Sciencedirect Topics

Coal dried with air at 250350 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.
