In both processes, beads are used as an aid for the transmission of mechanical energy. They are the tools that transfer their energy to the particles to be comminuted by mechanical forces and movement. The comminution takes place in bead mills, especially in the wet grinding process in so-called agitator bead mills.google mechanical comminution processes mills,google mechanical comminution processes mills .
