Ball mill. A ball mill, a type of crusher, is a cylindrical device used to grind chemicals or mix compositions. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium, ideally non sparking milling media like lead balls. An internal cascading effect reduces the material to a fine powder.

Pure aluminium in a ball mill forms spherical particles that get smaller until the competing process of particles rejoining forms a limiting fineness. With the right additives and pretreatment the aluminium tears into smaller particles with much more surface area than spheres, and keeps getting finer as milling progresses.
