Abstract
A particle-carrying feedstock is mixed by a rotor-stator mixing mechanism placed within a mixing chamber where mixing is conducted under a negative pressure for separating and removing entrained air from the mixed feedstock, preferably before passing the de-aerated mixed feedstock to a media mill for processing into a particle dispersion. The rotor of the rotor-stator mixing mechanism preferably includes a disk carrying vanes on opposite faces of the disk for a conducting simultaneous dual mixing operations. Openings in the stator are provided with an H-shaped cross-sectional configuration and are intermingled for facilitating the mixing operation while maintaining the integrity of the rotor-stator mixing mechanism.
