Abstract
Abstract Apparatus for mixing materials at increased shear rate and efficiency which utilizes upper and lower spaced rotary mixer blades each driven in the same direction by a rotary shaft. The upper blade consists of a group of inner material deflectors for moving mix material in one direction through the blade while an outer concentric group of deflectors move mix material in the opposite direction through the mixer blade. The lower mixing blade is then oppositely formed so that the inner circular array of deflector-slot configurations moves mix material through the blade in opposition to material from the upper plate inner deflectors while an outer concentric ring of deflectors move mix material downward through the blade away from the upper blade outer deflectors.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
123 words
Mixing apparatus of the type which is driven by rotary input, comprising: shaft means for receiving said rotary input; first blade means secured to said shaft and including first and second spaced concentric arrays of oppositely directed slotdeflector means which move mix material oppositely through said blade means; and second blade means affixed to said rotary shaft means and axially spaced from said first blade means and including first and second spaced concentric arrays of oppositely directed slot-deflectioN means which move mix material in opposite directions through said blade means; said opposite directions being opposite from those directions of movement of mix material through said first blade means such that a shear interface is set up between said first and second blade means.
Claim 2
Dependent Claim
123 words
Mixing apparatus of the type which is driven by rotary input, comprising: shaft means for receiving said rotary input; first blade means secured to said shaft and including first and second spaced concentric arrays of oppositely directed slotdeflector means which move mix material oppositely through said blade means; and second blade means affixed to said rotary shaft means and axially spaced from said first blade means and including first and second spaced concentric arrays of oppositely directed slot-deflectioN means which move mix material in opposite directions through said blade means; said opposite directions being opposite from those directions of movement of mix material through said first blade means such that a shear interface is set up between said first and second blade means.
Claim 3
Dependent Claim
125 words
Apparatus as set forth in claim 1 wherein said first blade means comprises: circular disc means including a central bushing receiving said rotary shaft therethrough in secure affixure, said disc means including an inner plurality of circularly arrayed radial slots formed about said disc means and an outer plurality of circularly arrayed radial slots formed concentric to said inner slots about said disc means; a first plurality of deflector means each secured on the top surface of said disc adjacent the trailing edge of each of said inner radial slots to force mixed material downward through the slots; and a second plurality of deflector means each secured to the under side of said disc adjacent the trailing edge of each of said outer radial slots.
Claim 4
Dependent Claim
107 words
Apparatus as set forth in claim 2 wherein said second blade means comprises: second circular disc means including a second central bushing receiving said rotary shaft therethrough in secure affixure, said second disc means also including an inner plurality of circularly arrayed slots and an outer plurality of circularly arrayed slots formed thereabout; a first plurality of deflector means each secured on the bottom surface of said second disc means adjacent the trailing edge of each of said inner slots; and a second plurality of deflector means each secured to the top side of said disc means adjacent the trailing edge of each of said outer slots.
Claim 5
Dependent Claim
25 words
Apparatus as set forth in claim 2 wherein each of said inner and outer radial slot arrays consist of four or more equispaced radial slots.
Claim 6
Dependent Claim
33 words
Apparatus as set forth in claim 3 wherein each of said first and second blade means has said inner and outer slots formed so that the blade means is approximately 25 percent open.
Claim 7
Dependent Claim
25 words
Apparatus as set forth in claim 5 wherein the open area of said inner slots is approximately twice the open area of said outer slots.
