ABSTRACT:
A dispersing and grinding apparatus comprises a vessel having an inlet at one end for supplying material which is to be ground and dispersed, and an outlet at the other end to discharge the ground and dispersed material. A rotor is rotatably disposed within the vessel and coacts with the inner wall of the vessel to define therebetween a narrow annular flow path through which the material flows from the inlet to the outlet of the vessel. An array of guide members are formed on the inner wall of the vessel or on the outer peripheral surface of the rotor for guiding the flow of the material-grinding medium mixture so that the predominant flow of the mixture in the narrow annular flow path occurs in the circumferential direction. The guide members have forward and rearward guide surfaces for imparting forward and rearward motions to the mixture as it flows circumferentially about the annular flow path. As the predominant mixture flow is in the circumferential direction, sufficient motion is imparted to the mixture to enable the grinding medium to grind and uniformly disperse the material as the material advances in the lengthwise direction through the narrow flow path to the outlet of the vessel.
