Abstract
Abstract A homogenization stirrer is disclosed comprising a rotor and a stator between which a rubbing gap is provided. The stator includes passages through which the homogenized medium is thrust out by the action of the running rotor. The stator comprises two interengaging parts defining gaps between them which form said passages, one of these stator parts being axially adjustable in relation to the other for adjusting the width of the passage gaps and thus the flow rate of the medium, or its dwell time in the stirrer.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
163 words
A homogenization stirrer for use with materials having differing ranges of viscoscity and homogeneity, the stirrer comprising; a rotor, a stator spaced from said rotor and defining a rubbing gap, means for rotating said rotor relative to said stator and including rotor blades for sucking a medium axially from one side and thrusting it axially towards the side opposite said one side, said stator comprising two interengaging parts both located on one and the same side of said rotor and defining a plurality of passage gaps between said two parts, said passage gaps forming a plurality of passages through which said medium is passed out of said stator for homogenizing the same, and means for axially adjusting spacing of one of said two parts in relation to the other part of said two parts for adjusting the width of said passage gaps in said stator and thus back pressure and flow rate to determine dwell time of the medium in the rubbing gap.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
37 words
A stirrer according to claim 1, wherein said last mentioned means comprise means for steplessly adjusting spacing between said two parts relative to one another and means for holding said two parts in any adjusted relative position.
