Bead mill: The bead will consist of tubular vessel made up of metal or glass within which small beads are kept. When vessel rotates, the beads also starts rotating but away from axis. The shear force and impact of beads causes disruption of cells. Advantages: It is very useful for small sized materials and it doesn't release harmful aerosols.
