Stirred ball mills are generally vertical and high-speed. The grinding balls in stirred ball mills acquire much higher impact energy than those in a traditional ball mill. Stirred ball mills can also handle greater quantities of powder than planetary or traditional ball mills.
2.2. Mechanical Treatment of Copper Powder For the grinding of the copper nanoparticles, a mixer mill (Retsch MM 400) having two stainless steel with 50 cm3 grinding jars and two stainless steel grinding balls (vol-ume: ∼8.2 cm3, diameter: 25 mm) were applied. The mill was operated using constant ball/sample weight ratio
The inert gas atomised prealloyed copper powder containing aluminium, i.e. Cu-3.5 wt.% Al, was milled for 3, 5, 10, 15 and 20 h in the planetary ball mill. The weight ratio of powder to steel balls was 1 : 35. The high energy milling was performed in the air in order to enable formation of alumina dispersoids by internal oxidation.
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. …
