Principle Crushing is used to very quickly produce a fine powder from a bulk material or fine particle using mechanical crushing. This technique is essentially used to investigate ceramics, minerals, and mixedcomposite materials. Materials must be brittle or made brittle and of a high hardness to average hardness.

The term 'gentle crushing' may sound somewhat contradictory, but compared with the raw power of impact crushing, compression crushing could be considered a much gentler method which makes it more favourable for harder, abrasive rocks. If impact crushing is opening a walnut with a hammer, compression crushing is the nutcracker method.

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].

Introduction to Crushing and Grinding of Bauxite. The most common initial process step to feed an alumina refinery with bauxite is the crushing or sizing of the raw bauxite material that is extracted from the mine. The feed material is crushed or sized so that it is conveyable, as well as correctly dimensioned, for the next step in the process.

A notable fact is that the energy efficiency of conventional milling is only about 1%, as mentioned in Sect. 1. An earlier experimental study indicated that about 8090% of the energy input of a ball mill was used in heating the material (Schellinger 1951, 1952), and a recent study showed that over 75% of the electrical energy was used to heat the slurry (Bouchard et al. 2016).
