Abstract
A continuous dispersing and grinding apparatus comprises a vessel having an inlet for feeding a material to be processed at one end and an outlet for discharging the processed material at the other end. A rotor is disposed rotatably within the vessel, and the material flows between the vessel and rotor from the inlet towards the outlet. The outer surface of the rotor is provided continuously with an undulations having alternate crests and troughs. The undulations define a repeating succession of distinct sections, namely, a compressing section for gradually compressing the material, a shearing section for applying shearing forces to the material, and an expanding section for releasing the compression of the material. As the material flows through the vessel in the space between the vessel inner wall and the rotor outer surface, the succession of compressing, shearing and expanding sections repeatedly subject the material to compressing, shearing and expanding actions whereby the material is uniformly dispersed and ground.
