The attritor ball mill, also known as stirred ball mill, is a kind of vertical ball mill. It can be divided into dry type and wet type, suitable for grinding a variety of materials, such as industrial ceramics, fireproof materials, silicate materials, metal powder, ores, etc. It is equipped with an agitation system inside the grinding cylinder.
High energy ballmill can also induce phase transformations in precursors such as: amorphization or polymorphic transformations of compounds, disordering of ordered alloys, etc., however, all these have similar chemical compositions. Alloys can be prepared by using different equipments such as, attritor, planetary mill or horizontal ball mill.

Mechanical alloying for commercial production is carried out in ball mills of up to 3000 lb capacity (Fig. 5). The milling time decreases with an increase in the energy of the mill. For example, a process that takes only a few minutes in the SPEX mill can take hours in an attritor and a few days in a commercial mill.
