Bead Mill - Working Principle. The bead mill consists of a horizontal grinding chamber, which in turn houses the shaft and agitator discs. The chamber is filled with zirconium grinding media and the material leakage is prevented by the double acting mechanical seal. The material is pumped into the chamber using a air operated diaphragm pump or ...
