Comminution is important in mineral processing, where rocks are broken into small particles to help liberate the ore from gangue. [3] Comminution or grinding is also important in ceramics, electronics, and battery research. [4] Mechanical pulping is a traditional way for paper making from wood. The mastication of food involves comminution.

Comminution Because most minerals are finely disseminated and intimately associated with the gangue, they must be initially “unlocked” or “liberated” before separation can be undertaken. This is achieved by comminution in which the particle size of the ore is progressively reduced until the clean particles of mineral can be separated by such methods as are available. Comminution in …
