Dispersing and grinding apparatus.

摘要

A dispersing and grinding apparatus in which a material to be treated and a grinding medium are placed in a grinding vessel and the mixture of the material and medium is provided with motion thereby the material is ground and dispersed into solution. The vessel (1) has an inlet (2) for introducing the material at one end and an outlet (3) for discharging the finished processed material at the other end. The vessel (1) is provided with a cylindrical rotor (10) rotatably therein so as to form a narrow space with the inner wall of the vessel. The outer circumference of the rotor or the inner wall of the vessel is provided with guide members (12) to control the flow of the mixture. The guide members (12) include forward guide (13) surfaces which give forward movement to the mixture and backward (16) guide surfaces which give backward movement. By means of these guide members, the flow of the mixture is possible similar to the plug flow state.
