· Coal parameters affecting pulverizer output. While selecting a pulverizer, the coal characteristics play an important role. The Hardgrove index, total moisture, input coal size, output fineness, and mill wear have direct impact on the mill output. The Hardgrove index of coal tells us about the ease with which it can be pulverized.

But additional equipment needed for separating air from pulverized coal before storing in the bin, and the conveying system itself, offset the economy of lower mill capacity. Presently, the central system has been discarded in favor of unit system owing to building requirements, high initial cost and compliions in most of the parts.
Thus, according to the abrasive quality of the coal and the type of pulverizer employed, a definite reduction in the weight of the grinding elements will occur per ton of coal ground. If the wear is uniform, the changes in the active mill parts may be made at satisfactory intervals; alternatively, shuttingdown for overhaul and replacements may become frequent.
