Abstract

A grinding and dispersing apparatus comprises a tank for storing a liquid containing a material to be treated and a container disposed in the tank for containing grinding media. The container has an inlet for receiving the liquid containing the material and a discharge outlet for discharging the liquid containing the material. A feeding mechanism is disposed at the inlet of the container for feeding the liquid containing the material into the container. A stirring mechanism extends into the container for stirring the grinding media and the liquid containing the material fed into the container to disperse the material in the liquid. A separating device is disposed at the discharge outlet of the container for separating the grinding media from the liquid containing the dispersed material and permitting the liquid containing the dispersed material but not the grinding media to be discharged from the container.
