Influence of preheating on grindability of coal. Int. J. Miner. Process., 36:107112. Enormous quantities of coal must be ground as feed to power generation facilities. The energy cost of grinding is significant at 5 to 15 kWh/ton. If grindability could be increased by preheating the coal with waste heat, energy costs could be reduced.
