Grinding Mill
Conventional dry grinding of coal in power plants has been carried out mostly with roller-race or ball-race mills. As wet grinding is preferred for coal slurries, another group of mills has come into use. The two possibilities are straddled best by the tumbling ball mill.

How does a Coal Mill Work?
A pulverizer coal mill works by grinding coal into a fine powder and then drying it in a hot air fan. The coal powder is then blown into a combustion chamber where it is burned to generate heat. The hot gases and heat energy produced from burning the coal powder then pass through a series of heat exchangers where the heat is transferred to ...
