grinding of coal


Posted on October 19, 2018



Coal pulverizing for coal-fired power stations | MagotteauxPulverizing coal consists in grinding coal as fine as possible prior to combustion in the steam-generating furnaces of fossil fuel power plants. Coal pulverization is essential to the overall system process of a coal-fired power station, not just in terms of furnace performance and heat rate but in terms of the mechanical reliability.grinding of coal,Grinding characteristics of coal and petroleum coke/coal blends on .Petroleum coke (PC) blend with coal is an attractive feedstock for combustion process. The present work investigates the grinding characteristics of PC blend with coal in a laboratory ball mill to meet an industrial tube mill conditions. Tests were carried out using a laboratory batch ball mill for optimal production of −200 mesh.
