· Drying the lignite from the moisture content of 37.90% (sample 1) to 16.61% (sample 4) resulted in a slight increase of input energy of about 0.04 kWh.t −1 per 10 s. However, further drying to reduce the inherent moisture to 0% would increase the input grinding energy by 0.16 kWh.t −1 per 10 s (sample 7 vs. sample 4).

· Lignite is considered to be a lowest-rank coal with high moisture and volatile content [1]. A very large proportion of the ‘non-caloric content’ – water, which is sometimes as high as 60%, absorbs a great amount of heat to evaporate during the combustion process, leading to a lower caloric value of lignite than that of the black coal.
