The bead mill, also referred to as the sand mill, is a kind of milling equipment used for particle size reduction and dispersion of solid particles in a liquid medium. The working of a bead mill is based on intense agitation and grinding between the solid particles and the grinding media (beads) within a cylindrical chamber. The chamber is typically filled with grinding beads made of materials such as zirconia, ceramic, or metal. There is an agitator in the chamber, usually in the form of a rotating shaft with discs or pins attached. Its high-speed rotation generates a strong turbulent flow within the chamber, causing the grinding beads and the material to collide and interact.

As the material is fed into the mill from one end, it is subjected to the high shear forces generated by the agitator and grinding beads. This intense agitation breaks down the particles, reducing their size and promoting dispersion. The grinding beads effectively grind and disperse the material, ensuring a uniform particle size distribution in the final product.
