Abstract
A pipeline beads mill has a dispersion chamber, a first feeding port for feeding a material to be treated into the dispersion chamber, a second feeding port for feeding a dispersion media into the dispersion chamber, a tubular outer stator disposed in the dispersion chamber, and a tubular inner stator disposed in the outer stator in spaced-apart relation thereto to form a treatment gap therebetween for receiving the dispersion media and the material to be treated. The inner stator has an outflow port in communication with the treatment gap. A tubular rotor is disposed in the dispersion chamber and partitions the treatment gap into an outer gap portion and an inner gap portion. A rotationally driven shaft rotates the rotor to displace the dispersion media so as to disperse the material to be treated. The rotor has a circulation port for permitting circulation of dispersion media between the outer gap portion and the inner gap portion of the treatment gap during rotation of the drive rotor. A discharge port is disposed in communication with the outflow port of the inner stator for discharging the dispersed material. A separating member is disposed at an inner side of the outflow port…
