Abstract
An agitator mill comprises a milling container and a rotor mounted therein. The rotor is built up in axial direction of individual rings and is provided with radially projecting agitator tools being integral with the rings and consisting of a wear-resisting material of good heat conduction. The rings are cooled by a cooling medium at their surfaces facing away from the grinding area.
Claims14
An agitator mill for continuous grinding and dispersing of material suspended in a liquid comprising a ring shaped grinding chamber defined by front sides of inner and outer corresponding wall means, wherein
- said outer wall means is a stator and said inner wall means is a rotor with a central rotor axis and
- at least one of said corresponding wall means is at least partially built up by ring means lined up along said rotor axis, wherein
- at least some of said ring means comprise agitator members projecting radially into said grinding chamber,
- said ring means have a rear side opposite to said front side,
- said agitator members are located at said inner and at said outer wall means in groups of corresponding agitator members, said agitator members including shear surfaces oriented radially to said rotor axis wherein said shear surfaces of corresponding agitator members are essentially parallel and leave under rotation a gap in the direction of said rotor axis smaller than the length of said agitator members, and
- said agitator members have a greater axial thickness at said wall means than at the free end of said agitator means.
