Waterspout- combo is a fully functional bead mill which has been designed for the use of micro beads in the extremely wide parameter range for completely different applications in nano processing. It can be operated flexible in use for batch or recirculation mode. Dual shaft structure is employed to enable independent driving. It's suitable for the use of micro beads in a high viscosity of nanodispersion. The true value of this new bead mill could be demonstrated in the nanodispersion with weak particle strength and high viscosity dispersion which was proved difficult in the traditional nano bead mills.
