Abstract
The mixing apparatus comprises a mixing container with vertical axis which mixing container comprises an interior space and an outer annular space, communicated with the interior space by an annular gap. Within the interior space, there is performed a size reduction of the material to be mixed into granulated material which enters the outer annular space through the annular gap. The annular gap has comb-like openings so that only parts of small size are allowed to pass through.
Claims12
A continuous mixing apparatus comprising:
- a. a mixing container having a container bottom;
- b. a concentric ring wall disposed within said container and dividing it into an interior space whose outer periphery is defined by said ring wall and an outer annular space whose inner periphery is defined by said ring wall, said ring wall terminating in a bottom edge thereof disposed above said container bottom;
- c. a feeding nozzle in flow communication with said interior space to introduce mixture components therein;
- d. discharge opening means leading from said outer annular space;
- e. a central agitator shaft supporting mixing wings for rotation within said interior space adjacent said container bottom;
- f. a rotor ring carried by said mixing wings at a location radially spaced from said agitator shaft and disposed adjacent said bottom edge of said ring wall to define therewith a gap of selected width disposed above said container bottom and radially spaced from said shaft whereby mixture particles of a size not greater than said width of said gap are passed, by rotation of said wings, from said interior space to said outer annular space for removal therefrom via said discharge opening.

A continuous mixing-cooling apparatus comprising:
- a. a mixing container having a container bottom;
- b. a concentric ring wall disposed within said container and dividing it into an interior space whose outer periphery is defined by said ring wall and an outer annular space whose inner periphery is defined by said ring wall, said ring wall terminating in a bottom edge thereof disposed above said container bottom and containing means to pass a coolant therethrough;
- c. a feeding nozzle in flow communication with said interior space to introduce mixture components therein;
- d. discharge opening means leading from said outer annular space;
- e. a central agitator shaft supporting mixing wings for rotation within said interior space adjacent said container bottom;
- f. a rotor ring carried by said mixing wings at a location radially spaced from said central shaft and disposed adjacent said bottom edge of said ring wall to define therewith a gap of selected width between said rotor ring and said bottom edge of said ring wall, said gap being radially spaced from said shaft;
- and
- g. a plurality of vertically projecting members supported on at least one of said rotor ring and said bottom edge of said ring wall and disposed along the periphery thereof to project across said gap in a comb-like configuration whereby only mixture particles of a size not greater than said width of said gaps are passed, by rotation of said wings, from said interior space to said outer annular space for removal therefrom via said discharge opening.
