It was found that the ball mill consumed 54.67 kWh/t energy to reduce the F 80 feed size of 722.2 µm to P 80 product size of 275.4 µm while stirred mill consumed 32.45 kWh/t of energy to produce the product size of 235.6 µm. It also showed that stirred mill produced finer product than the ball mill at around 40% lesser consumption of energy.

These materials are synthesized via ball milling, followed by dc hot pressing. The ZT enhancement comes mainly from a large reduction in the phonon thermal conductivity but also benefits from a reduction of bipolar contributions to the electronic thermal conduction at high temperatures.
The decreasing relative intensity of the main peak of ZnS at ~33.28° with increasing milling time (Fig. 1) shows the reduction reaction occurs gradually. It is worth noting that amorphization, a well-known phenomenon during high-energy ball milling, results in not only decreased peak intensity but also broadening of the peak width [ 2 ].
