Abstracts: • Bead Mill reduce particles to sub micron size. So it’s called secondary grinder. Consisting of a cylindrical vessel that contains a motor-drive central shaft, which is equipped with impellers of different types. • Bead mill comes with an enclosed vessel while operating this enclosed vessel is filled with grinding media, agitator shaft activates media creating shearing and strong forces. • Rotation of agitator imparts energy to surrounding media. Forces either fracture tear are crush particulate. • It can be operated continuously, it is equipped with devices, which retain the beads within the milling chamber. Then the final product is evenly dispersed in liquid. • This bead mill are batch process machine for size reduction and dispersing of paints, inks, coating etc. • The bead mill consist a grinding vessels inside which rotates of S.S. shaft fitted with impeller disc. The grinding media and the charged material are filled in to the vessel and the shaft is run at very high speed for a particular time till dispersion is achieved.
