Emulsifying and dispersing apparatus

An emulsifying dispersing apparatus comprising:

• a plurality of concentric cutting rims rotatable relative to each other, mounted in radial alternation on a stator and on a rotor, having a common axis of rotation, said rotor being rotatable relative to said stator;
• said rims including interacting teeth and defining therebetween a cavity which serves as a central feed chamber, and said teeth further interacting at very high speeds;
• a hollow tubular mounting of said stator for a shaft of said rotor;
• wherein opposite cutting flanks of said teeth are rotatable relative to one another in parallel alternation, said flanks being inclined at an acute angle to the common axis of rotation toward respective adjoining sides, when viewed from opposite directions, adjusting means for the axial displacement and adjustment of respective rims toward one another on said stator and said rotor, and thus of a clearance gap between said cutting flanks, to facilitate relative axial adjustment between said rotor and said stator even during operation of the apparatus;
• wherein the magnitude of the angle of parallel flanks of radially consecutive ones of said rims decreases to the common axis of rotation, looking from said feed chamber toward an outside one of said rims;
• and wherein said teeth are pyramidal in the radial cross-sectional direction and rectangular in the peripheral cross-sectional direction;
• the tooth roots between teeth of said consecutive rims lying higher than the tooth roots between adjacent teeth of the same rim, with the exception of the tooth roots of an outermost one of said rims;
• further comprising threaded means for lengthwise adjustment of said tubular mounting with respect to said shaft, by rotating said stator with respect to a portion of said mounting, lockscrew means for locking said adjustment means relative to said mounting, and a vernier scale on said stator coordinated to markings on said tubular mounting.
