What is difference between High energy ball milling and...

There is no fundamental difference, only the attritor with the same mass of equal balls grinds 5-10 times faster. Seen from the other side, only small attritors exist, and the large ball mills are anyway more efficient than small attritors. From a purely economic point of view, the attritors have little meaning, ball mills are cheaper,...

Ball mill - Wikipedia

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...
