Breakage process of mineral processing comminution machines …
Comminution environment properties involve comminution temperature, loading mechanism intensity, and wet or dry comminution. Besides, particle breakage mechanism can be influenced by external factors such as pre-treatment, for instance, chemical pre-treatment [2], [106], [107], thermal, electrical, or ultrasonic weakening [108].
