A classification of comminution equipment and conditions influencing the mechanical processing of rawmaterials components for obtaining oxide ceramics is presented. It is recommended on the basis of an analysis of comminution (dispersion) and mechanochemical activation of alumina that impact (pressure) — shear (tube, vibratory, planetary, and so forth) mills be used. Mills with average ...

A systematic study on the comminution of a soft (coal) and a hard (iron ore) material is carried out to investigate the bulk comminution features of the hammer mill. The effect of the feed rate and the rotor speed on the mill efficiency in terms of reduction ratio, energy expenditure, fines produced and median size is investigated.

Comminution and industry drivers. Comminution is the class of processes relating to the deliberate reduction in the size of particles. This is a critical and very energy intensive step in production of base metals, light metals, precious metals and iron ore which form the basis of our industrial and consumer economy.

As with any material, rock particles only break when the applied tensile stress exceeds the tensile strength of the rock. However, in terms of comminution, the main interest is to derive reliable ways of assessing how a particular material breaks in a comminution device such as a crusher or a mill [].In general, the breakage of rock particles is dependent on two factors: the "hardness" of ...
