  • Ball Mill

    Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

    In order to limit the starting current of the motor, star-delta starting can be used for grid fed induction machines. The induction machine is started in star connection and later switched to delta connection. This reduces the starting peak current to one third (see Figure 9). However, the starting torque is also reduced to one third.
