A bead mill is a type of equipment used for ultrafine grinding and dispersing of particles. It operates on the principle of impact and attrition: grinding media (beads) made of glass, ceramic, or steel are agitated inside a vessel or a chamber by a rotating shaft with impellers, causing the particles to break into smaller sizes due to collision and shear forces.
