Bead Mills are designed for dispersion processing, where solid particles (pigments, fillers) are reduced in size and finely dispersed and wetted out in a liquid phase. Small ceramic, glass or metal beads are agitated inside the mill chamber to aid particle size reduction through impact and energy input. Post dispersion the mill base is pumped to the let down tank for completion.

Abigail's Bead mills are one of the most effective methods for processing particles into micron to sub-micron size range. A wide variety of designs exist to adapt to the different viscosities, material characteristics and targeted particle size dispersions. Depending on the machine design, bead mills are operated in discrete pass or continuous operation. MOC of discs can be varied depending on the requirement.
