comminution, is performed in ball mills using steel balls as the grinding medium. The ball mill, after feeding 0.5 mm material may give a product that is less than 100 microns. Grinding is usually done wet. The principle purposes of grinding are: – i. To obtain the correct degree of liberation in mineral processing. – ii.

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 differed among themselves

cannot collect the wanted components only. The second objective of comminution in mineral processing is to adjust the size of mineral particles to adapt to the optimum size for the successive separation processes. Screens and classifiers are used to adjust the particles within prescribed and closer size range.

Comminution. The process of comminution is the crushing and grinding of a material / ore to reduce it to smaller or finer particles. The comminution process reduces particle sizes by breaking, crushing, or grinding of ore, rock, coal, or other materials. The process is most often used in the field of mining and / or mineral processing, where
