Reducing the moisture content of clean coals Volume 2:

Dec 01 1992 Abstract. Coal moisture content can profoundly effect the cost of burning coal in utility boilers. Because of the large effect of coal moisture the Empire State Electric Energy Research Corporation ESEERCO contracted with the Electric Power Research Institute to investigate advanced coal dewatering methods at its Coal Quality Development Center.

PDF The effect of moisture content on the grinding:

The grinding behavior of corn and corncobs was investigated at moisture content levels of 10.39 16.02 and 19.64 wet basis for shelled corn and 10.04 14.65 and 20.13 wet basis for corncobs. Grinding performance was assessed by determining the throughput specific rate of breakage particle size distribution power consumption and energy required for grinding using a hammermill.

Excessive drying of coal should be avoided due to the accelerating process of oxidation which occurs as the moisture content is reduced with the consequent risk of spontaneous ignition.In practice drying off the surface moisture of the coal and a small part of the

coal utilization Volatile Matter amp Chemistry Britannica:

Two factors affecting grindability are the moisture and ash contents of a coal. In general lignites and anthracites are more resistant to grinding than are bituminous coals. One commonly used method for assessing grindability is the Hardgrove test which consists of grinding a specially prepared coal sample in a laboratory mill of standard design.
