Assuming the efficiency is , the power required to remove the material is the same as the power used by the machine's motor. Each machine has a maximum power limit that it can handle. Therefore, it is helpful to calculate the power required to perform a machining operation such as milling or turning and compare it to our machine's ability.

The mill designer usually asks for 5- 10 % reserve, because variations in the mill charge increase the power requirements. Another 10% is necessary when running the mill without feed; in this case the mill pulls more power. Also, voltage variations can cause an increase in the motor power input. Gearless ball mill drive
