introduction. coal mill is a machine that breaks coal into pulverized coal. it is an important equipment of pulverized coal furnace.coal grinding process is the process of coal being broken and its surface area increasing.to increase the new surface area, the binding force between the solid molecules must be overcome, thus consuming energy.coal is ground into pulverized coal in a coal mill.kriel power station, mpumalanga,the tubing in the boiler walls contains feed water that absorbs the heat from the burning coal and is converted into steam. the coal is fed into the pulverised-fuel mills with the help of feeders, where it is ground to thin powder by steel balls running in a circular motion. the pulverised coal is transported to the boilers through primary air..duvha power station,coal is fed to the mills from the boiler bunkers, which is then pulverised by steel balls or rollers in the mills. the coal is supplied by ingwe, under an agreement signed in 1995. each boiler has six mills and can process between 250t and 300t of coal an hour at full capacity to generate 507kg/s of steam..tangshan steel supply cut after coal-fired mills shut from,tangshan steel supply cut after coal-fired mills shut from oct 9 the tangshan government has started the process of shutting steel mills which are have not switched their production feedstocks from coal to gas from this week, provincial authorities said in a public notice on october 11.
