Abstract

An apparatus for conveying, comminuting and mixing materials comprising/not comprising solid matter having a stator (8) featuring teeth extended inwardly comprises a plurality of racks (13) arranged alongside each other. These racks (13) are held at the ends of the stator (8) in fixing rings (15). The racks (13) may be arranged with a spacing (17) from each other which is defined by blades (16) formed on the fixing rings. The toothed sections of the rotor or impeller (7) and of the racks (13) may be arranged replaceable. Between the inner wall (22) of the casing (2) and the outer wall (21) of the stator cylinder a discharge passage (20) is provided which in a special embodiment is flared scroll-shaped in the direction of the discharge opening (6).

Dependent claims

An apparatus for conveying, comminuting and mixing materials, comprising a casing having an inner wall and an inlet opening;

a stub shaft extending into said casing opposite said inlet opening;
a discharge opening in said casing at a right angle to said stub shaft;
a rotor secured to said stub shaft and extending up to said inlet opening;
a stator arranged about said rotor in said casing, spaced inwardly from said casing inner wall;
said stator further comprising two spaced-apart fixing rings, each ring having an outer circumference with radially extending blades of predetermined thickness and spacing, and a plurality of racks seated between said blades an extending between said spaced-apart fixing rings;
said racks having an arrangement of teeth facing said rotor and said rotor having an arrangement of teeth facing said rack teeth and coacting therewith;
whereby material being conveyed is forced between said racks and between said casing inner wall and said stator, and out through said discharge opening.
