Coal Mills For All Requirements Gebr Pfeiffer

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.Hard coal is a sedimentary rock which was formed by deposition and carbonization of plant remains.
