Macro or micro scale particles are ground in a ball mill, a planetary ball mill, or other size reducing mechanism. The resulting particles are separated by filters and recovered. Particle sizes range from tens to hundreds of nm. Broad size distribution and varied particle geometry. May contain defects and impurities from the milling process.

The document summarizes the ball mill, which is a grinder used to grind and blend materials. It discusses the basic parts of a ball mill including the hollow cylinder and balls. It then explains the principle of operation through impact and attrition. The document also covers the theory behind maintaining critical speed for optimum efficiency.
