Product particle size of ball mill

Ball mills also tend to have a greater reduction ratio as well as a lower rate of reduction, thus making them more preferable over other kinds of mills [2]. But like any of the other mills, as previously mentioned ball mills have a very low efficiency in terms of utilizing the energy generated towards particle size reduction
