It was found that the ball mill consumed kWh/t energy to reduce the F 80 feed size of µm to P 80 product size of µm while stirred mill consumed kWh/t of energy to produce the product size of µm. It also showed that stirred mill produced finer product than the ball mill at around 40% lesser consumption of energy.
