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 pebbles, and stainless steel balls.

Wet media milling is a mechanochemical method to reduce the particle size to the nano-size, which is a necessary step for all the LFP synthesis processes. During milling, mechanical energy induces the collapse between the media (a hard material, such as yittria-stabilized-zirconia), and the particles in a liquid medium.
