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.

The silver (Ag) powder was synthesised in a mechano-chemical (MC) process by inducing a solid-state displacement reaction between silver chloride (AgCl) and copper (Cu). The AgCl and Cu were ground in atmosphere conditions using a planetary ball mill. The reaction caused the mixture of AgCl and Cu to change

Materials such as clay and glaze components can be broken down in a ball mill by getting placed into rotating or rolling jars with porcelain balls inside them. 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

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.
