Effect of media size in stirred ball mill grinding of coal
Mills having capacities greater than 20 t/h have reportedly been used to micronize coal to a median size of 6 lAm. Furthermore, Sepulveda [10] has shown that when grinding a Lower Freeport coal to a median size of 8 /Am, energy savings of approximately 60% can be achieved by using a stirred ball mill over a conventional ball mill.
