High

energy transfer by sphere collisions depends on the operational parameters, e.g. balls diameter, angular speed and ball/powder mass ratio. [15]. For instance, in order to obtain the intermetallic Nb3Al from a powder mixture containing Al-75%atNb, one have to heat during 2 hours at 825C a powder already mixed by 5 hours via HEBMP.

Ball mill

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
