Abstract: TiFe compound was produced by high-energy ball milling of TiH 2 and Fe powders, followed by heating under vacuum. TiH 2 was used instead of Ti in order to avoid the strong particles adhesion to grinding balls and vial walls. Mixtures of TiH 2 and Fe powders were dry-milled in a planetary mill for times ranging from 5 to 40 hours.

The prepared silver powder was mechanically deformed and refined with increasing milling time until all the silver oxide was reduced to silver. Continuing milling resulted in the agglomeration of the silver powder. The mean crystallite size of the silver prepared after 22 h of ball milling was calculated about 28 nm.

During milling, the porcelain balls pulverized the materials into an incredibly fine powder. Ball mills can be used to further break down or refine a single material, or you can place multiple materials into a ball mill jar to mix as you pulverize -- this is a very common industrial solution for mixing glazes that require the smallest of mesh sizes. Ball mills basically function like a mortar

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Fine silver powder was synthesized in a mechanochemical process by inducing a solid‐state displacement reaction between AgCl and sodium. The process employed was ball milling in a planetary‐type ball mill. The reaction products were elemental silver and NaCl in powder form.
