Effect of moisture on energy

nbsp 0183 32 Usually the grindability of lignite HGI index is higher than that of coking coal It is necessary for the lignite to remain in the mill for a longer time to sustain the adequate breaking As shown in Fig 3 the energy expended in pulverizing coal with moisture below the air-dried level was clearly higher than that of coal with moisture above the air-dried level...
