    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.

    Hard coal is a sedimentary rock which was formed by deposition and carbonization of plant remains. It is hard and resistant. More than 50 of its weight is made up by carbon. Therefore it is classified as high-rank coal. Other fossil fuels like sub-bituminous coals with high moisture contents as well as brown coal and lignite are lower ranked.
