The milling time and mill rotational speed were varied in four levels. The morphology of the synthesized powders was investigated by the FESEM and TEM image as well as XRD patterns. The results have revealed that the nanosized amorphous silica particles are formed after about 6 h ball milling and they are spherical in shape.

In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies. There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
