Abstract
An apparatus for the mixing of materials such as synthetic polymers and their additives. The apparatus comprises a casing which surrounds a cylindrical rotor. A series of groove rings and spacer rings are axially arranged on the rotor and in the casing. The grooves formed on the peripheral surface of the groove rings are circumferentially separated by shearing lands and are bound along their longitudinal side faces by the side faces of the alternately arranged spacer rings. In assembly, the grooves formed in the rotor groove rings are arranged in a partially overlapping, axially displaced relationship with respect to the radially opposed grooves formed on casing groove rings.
Claims6
An apparatus for mixing materials such as synthetic polymers and their additives, said apparatus comprising:
- a casing surrounding a cylindrical rotor,
- a series of profile rings consisting of groove rings and spacer rings axially arranged in alternating sequence on said rotor and is said casing which are in snug axial engagement with one another,
- said groove rings having grooves formed in their peripheral working surfaces which are circumferentially separated by shearing lands and which are limited in an axial direction by the end surfaces of said spacer rings abutting upon the end surfaces of said groove rings, said shearing lands and end surfaces defining said grooves as a series of individual closed chambers, and
- said grooves formed on said rotor groove rings being arranged in a partially overlapping, axially displaced relationship with respect to the radially opposed grooves formed on said casing groove rings so that the material will flow between said overlapping rotor and casing closed groove chambers thereby causing repeated dispersal of the material as it moves through the mixing apparatus.
