Owing to the rotation of balls (Equation (2)), every part of the ball's surface was in effective contact with the copper electrode. The device forms a 3 mm thick threedimensional mesh friction layer with a small ball as the carrier, plus a nanofiber structure, which improves the effective contact area in the macro and micro aspects separately.

Fig. 2 shows the variation of the average torque and power with mill speed for the ball mill described above with a fill level of 50%. The torque increases slowly until the peak is attained around N=80%.As the amount of cataracting increases, the balance of the charge improves and the torque required to maintain the asymmetric charge position declines steadily.
