Wet Media Milling. Particles are dispersed in a liquid slurry and media milled to obtain a uniform particle size distribution. The shearing forces (tearing apart), impacting (crushing by outside forces), and attrition (tearing and crushing each other apart) create particle distributions in the nanometer or sub-micron ranges.

 — Grinding Media Size and Weight: The size and weight of the grinding media can dramatically influence the milling action. Balls made of more dense media can produce a coarse grind, while lighter balls lead to a finer grind. The choice of media depends on the material being milled and the desired particle size.
