The First Principle of Comminution It sometimes happens that the obvious is long disregarded, and this applies to the first principle of comminution. Over the years many careful laboratory investigations of comminution phenomena have been made and published. These included accurate measurements of energy input and product size particle distributions, but the results …

Comminution is a group of mineral processing techniques used in extractive metallurgy to reduce the particle sizes of rocks. Comminution processes are used to turn rocks into powder because subsequent processing generally requires finer particle sizes.

11· An essential section of minerals processing is the size reduction or comminution of the ore. This is achieved with series of comminution and classification units such as crushers, mills, screens and hydrocyclones. The performance of each unit or a sub-process contributes to the total efficiency of the entire process.

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 …

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.
