Claims
- 1. A micro-mill mixer comprising in combination:
- an enclosure for treating material, the material including particles carried in a fluid,
- an inlet means in said enclosure for introducing material to be treated into said enclosure, an outlet means for discharging from said enclosure material for which treatment has been completed,
- an abrasive member having at least one face provided with an abrasive coating forming hard, sharp crystalline cutting points,
- at least one accelerator propeller providing both centrifugal and centripetal motion of said material, said propeller having blades for projecting the fluid and particles toward the abrasive member, and means for effecting flow of material into said accelerator propeller, so that ejected material continuously re-enters the accelerator propeller to effect repetitive circulation,
- said propeller and said abrasive member being positioned relative to one another so that the particles and the fluid are projected onto said abrasive member and against said abrasive coating to produce intense splitting, slicing and particle shearing as well as fluid division jointly with coating of said particles by said fluid to form an intimate mix, and said propeller and abrasive member being furthermore positioned so as to provide a continuous repetitive circulation of said particles and fluid over said abrasive member.
- 2. Mixer according to claim 1, including a stationary abrasive member in said enclosure and wherein the accelerator propeller is an encircled screw propeller having axial ejection, said propeller being disposed in cooperating relationship with said stationary abrasive member.
- 3. Mixer according to claim 1, wherein the accelerator propeller is an encircled screw propeller with axial ejection and cooperating with a rotatable abrasive member.
- 4. A micro-mill mixer according to claim 1, including baffles in said enclosure and wherein the accelerator propeller is a turbine impeller including adjustable teeth.
- 5. Mixer according to claim 4 including a plurality of abrasive accelerator discs mounted on a drive shaft extending into the enclosure and providing both centrifugal and centripetal motion of the particles and fluid and wherein said abrasive accelerator discs are provided with pins coated with abrasive material.
- 6. A micro-mill mixer according to claim 1, wherein the accelerator propeller is a rotor pump disposed in a pump housing provided with an inlet conduit sucking fluid from the enclosure, and an ejection conduit whose outlet emerges adjacent the enclosure bottom where it ejects the fluid onto the abrasive member.
- 7. A micro-mill mixer according to claim 1, wherein the fluid is a gaseous fluid, the accelerator propeller being a blower provided with an ejection conduit appropriate for treatment of particles carried in the gaseous fluid.
- 8. A micro-mill mixer according to claim 1, wherein the accelerator propeller is a pump rotor disposed in the enclosure provided with an inlet conduit sucking fluid into said enclosure and an ejection conduit provided inside with an Archimedes modified screw with abrasive coating.
- 9. A micro-mill mixer according to claim 8, wherein the ejection conduit is straight.
- 10. A micro-mill mixer according to claim 8 or 9, wherein the Archimedes screw is sectioned.
- 11. A micro-mill mixer comprising an enclosure for treating particles carried in a fluid to be accelerated in said enclosure, a plurality of abrasive accelerator discs mounted on a drive shaft extending into the enclosure and providing both centrifugal and centripetal motion of the particles and fluid, said abrasive accelerator discs cooperating with a plurality of stationary baffles having on both faces abrasive material, said baffles extending from the enclosure inner wall toward the drive shaft, said baffles defining a central opening through which said drive shaft extends, said baffles conducting the fluid and particles toward and through successive openings in the direction of successive abrasive faces of said plurality of rotating abrasive discs so that the particles and the fluid are projected onto said abrasive discs to produce intense splitting, slicing and particle shearing as well as fluid division jointly with coating of said particles by said fluid to form an intimate mix.
- 12. Mixer according to claim 11, wherein said abrasive accelerator discs are provided with pins also coated with abrasive material.
- 13. Mixer according to claim 11 or 12, wherein said stationary baffles are provided with pins also coated with abrasive material.
