Development of a Tube-ball Coal Mill Mathematical Model Using .

Coal-fired stations are now obliged to vary their outputs in response to changing electricity demand (load following operation) and are required to operate more flexibly with more varied coal specifications. Mill controls need to respond effectively to changes in plant load and coal quality. [6]. The Tube Ball mill used by EDF is.

Coal-water slurry fuel - Wikipedia

In the late 1950s, the Soviet Union looked for new methods of using coal sludge for power generation. Coal-water slurry fuel was made in a ball mill which pulverised the coal or coal sludge. This was done near a coal mine in Belovo, Siberia. The coal-water slurry fuel was transported through a pipeline to Novosibirskaya.
