Research suggests that the most significant energy savingsperhaps greater than 25%might be achieved through a hybrid coal grinding approach in which coal is first crushed in a highpressure roll mill and then deagglomerated in a ball mill. This report describes the hybrid approach and evaluates its use in connection with four different coals.
