  • This application relates to mills and to methods of using such mills for the densification of materials.
  • this application relates to a high G mill and to a system and method for subjecting material particles and an additive to a mill to comminute and blend the particles, and a spray dryer to dry the particles.
  • Silver (Ag) is one of the most electrically conductive materials in the world and is on par with the conductivity of gold (Au) and copper (Cu). Silver and gold, along with palladium (Pd) and platinum (Pt), are precious metals. Copper, nickel (Ni) and aluminum (Al) are considered to be base metals while tungsten (W) and molybdenum (Mo) are considered to be refractory metals due to their extremely high melting points . These precious, base and refractory metals would all benefit from an effective de-agglomeration and densification process.
  • the above materials are all employed in a variety of electronic applications to include: screen-printed conductive patterns on various substrate materials including alumina (Al 2 O 3 ) for hybrid microcircuits and integrated electronic packages such as low temperature cofired ceramic tape (LTCC); electrodes and terminations for chip components, such as ceramic chip capacitors and resistors; screen printed metallizations on silicon (Si) wafers (solar cell applications); and coatings on Si chips in one form or another (e.g. die attach to heat sinks for the semiconductor industry).

  • Broad-based applications by market segment include circuitry for automotive, medical, military, semiconductor, consumer, solar and telecom markets. More specifically, examples of applications include
  • the most versatile and popular material for all of the above applications is silver due to its excellent conductivity, low cost, availability and compatibility with other circuit elements.
  • the primary form of Silver is a powder so that it can be incorporated into thick film screen-printable formulations. Fine, well-dispersed or de-agglomerated powder (micron-size range) is ideal so that fine circuit patterns and thin layers can be achieved. Most powder processes involve precipitation of some sort using metal salts and the resultant material is usually agglomerated and porous (both intra- and inter-particle porosity).
  • Dense powder leads to greater conductivity as porosity reduces the speed and density of the transfer of electrons. More dense powder also leads to better power handling capability in the various applications and reduced sensitivity to environmental conditions such as humidity, temperature and bias voltage. Silver, in particular, is sensitive to these conditions because silver, more than any other conductor, tends to migrate, i.e., to form Ag dendrites under humidity and bias voltage conditions which lead to shorting phenomena. Thus, dense fine Ag powder is ideal.
  • Typical methods currently used for densification of metal powders include: ball milling; jet milling (which is usually done in a nitrogen jacket due to Ag oxidation issues and becomes very expensive under these conditions); attritor milling; and horizontal bead milling.
  • These processes have shortcomings in the metal powder densification arena that can be related to inefficiency to include: low yields which are not acceptable when working with expensive precious metals; introduction of contaminants; and alteration of the starting morphology.
  • An example of altered morphology is the production of flakes from spheres or irregularly-shaped particles due to repetitive impact of some processes. In most applications, this flaking or flattening outcome is not desirable as a goal, although flaking or flattening is a goal in certain applications.
  • the goal is to de-agglomerate in order to increase the tap density of the material while maintaining the generally spherical shape of the particles (not alter the physical characteristics such as the morphology of the powder).
  • the material before processing is agglomerated such that several primary particles are grouped together, creating lager units of material with gaps formed therein. It is desirable to de-agglomerate these larger units into primary particles without changing the morphology.

Particles larger than Vz" in diameter to less than a micron maybe introduced into the mill 904, depending on the features of the mill itself.

  • the particles could be fed into mill 904 as part of a slurry, e.g., a mixture of material particles and a fluid.
  • the fluid could be aqueous or non-aqueous, such as, for example, water or organic fluids such as alcohols and oils.
  • Introduction of a solid additive to mill 904 produces a mixture of comminuted material and additive.

  • the additive can be introduced at different stages of the mill to achieve different comminution ratios.

For example, if the additive is introduced at the beginning stage of the mill, along with the material, the additive and the material may have roughly the same size reduction ratio, as both the material and the additive are subjected to the same milling process.
  • the binder In order to obtain a thin coating of binder, the binder must be spread evenly over the individual solid particles with a minimum possible thickness. This is achieved by either lowering the viscosity of the binder or forcing the binder, under pressure, to penetrate and spread evenly over the particles.
  • the lower viscosity range of a binder is limited. Exceeding the lower limits of the range results in binder that segregates from the particles, dripping down the product, and resulting in degradation of its lubricating properties required during subsequent powder compaction. It is advantageous to use as little binder as possible, while obtaining a sufficient coat on each particle. This reduces the occurrence of voids and gaps when the binder is removed during sintering.
  • Suitable binders for use in a mill comminuting alumina powder are methyl-methacrylate ("MMA") and Cyanoacrylate. These binders are not water soluble, and therefore, are not subject to being dissolved if water is the energy transfer fluid used in a fluid energy mill. Furthermore, these binders exhibit the desired properties of having a fast polymerization with a controllable reaction. MMA polymerizes under standard atmospheric conditions. Therefore, it is necessary to add an inhibitor. For example, adding up to 0.1% of an inhibitor such as Topanol or Hydroquinone to the MMA solution will prevent polymerization at atmospheric pressure.
  • an inhibitor such as Topanol or Hydroquinone
  • the binder material not be dissolved by the fluid used for energy transfer in a fluid energy mill.
  • dissolution of the binder material is permissible if the binder has a lower vapor pressure than the vapor pressure of the fluid used for energy transfer in the mill. This allows the fluid to vaporize in the spray dryer and leaves behind the binder material to form a thin coat over the dried solid particles.
  • binders that could be used in the present invention include but are not limited to: CARBOWAX ® Polyethylene Glycols, manufactured by Union Carbide Chemicals and Plastics Co., Inc. of Danbury, CT and Methocelcellulose ethers, manufactured by DOW Chemical of Midland, MI. Polyvinyl alcohols can also be used.
  • a solvent can be used as the additive, rather than a binder, to initiate reaction of the materials in the fluid energy mill.
  • the solvent is preferably miscible with the fluid used for energy transfer.
  • the solvent could be used as the energy transfer fluid if high concentrations of solvent are required for complete dissolution.
  • spray dryer 908 is attached to feed pump 906, and is comprised of atomizing components, such as a nozzle 1004 and a heating chamber 1006.
  • atomizing components such as a nozzle 1004 and a heating chamber 1006.
  • a spray dryer mixes a spray and a drying medium, such as air, to efficiently separate the particles from the fluid as the particles fall through the air.
  • Drying occurs as the atomized spray is subj ected to a heat zone in chamber 1006 or, alternatively, a hot gas, such as air or an inert gas as described above, is injected into chamber 1006. Flash drying quickly evaporates the fluid from the slurry, leaving only the dry particles.
  • the small size of droplets allows quick drying, requiring a residence time in the heat zone ranging from 1-60 seconds, depending on the application. This short residence time permits drying without thermal degradation of the solid material.
  • the resulting collected particles are fine, dry and fluffy.
  • the spray dryer can be used for drying any slurry, whether the slurry is comprised of particles of amaterial, an additive, and a fluid or comprised of only particles of a material and a fluid. Further, the spray dryer can be a standard spray dryer, known in the art of spray drying. Spray dryer manufacturers and vendors include companies such as U.S. Dryer Ltd. of Migdal Ha'emek, Israel, Niro, Inc. of Columbia, MD, APV of Rosemont IL, and Spray Drying Systems, Inc. of Randallstown, MD.
  • a conventional spray dryer can be outfitted with condenser 910. Because all drying takes place in an enclosed chamber 1006, capture and condensation of the vapors is easily performed. Condenser 910 collects the vaporized fluid from chamber 1006 and allows the spent fluid to be recovered. Thus, spray drying offers a simple way to contain the vapors from the evaporated fluid.
  • Fluid recycling circuit 914 can connect condenser 910 to optional high pressure pump 902 located at the beginning of the mill. This allows condensed fluid to be recycled by returning the used fluid from the spray dryer to the mill. This reduces waste and contains the fluid, which is especially important when the fluid is a regulated product, such as isopropanol.
  • the fluid is water
  • the water can be released from the spray dryer as vapor, can be condensed to be discarded, or can be recycled through the fluid recycling circuit. It would be apparent to one skilled in the relevant art that a variety of fluids could be used as the fluid in the mill.
  • the slurry is introduced from the mill directly into the spray dryer.
  • This embodiment does not use a feed pump connected to the nozzle for atomizing. Instead, fluid restrictors are used at the mill outlet to maintain the high pressures in mill 904.
  • the slurry bypasses feed pump 906 and is injected directly from the outlet of mill 904 into spray dryer 908.
  • the fluid pressures at the outlet of mill 904 must be sufficiently high to achieve complete atomization of the slurry.
  • FIG. 11 shows another embodiment of system 900 for comminution, blending and processing materials into particles.
  • This embodiment includes a hydrocyclone 110 located between mill 904 and feed pump 906.
  • Hydrocyclone 1110 can be located either before or after feedpump 906, but is preferably located before it.
  • a second feed pump (not shown) can be used to introduce slurry from mill 904 to hydrocyclone 1110, or, the slurry can be introduced into hydrocyclone 1110 directly from mill 904, as shown in FIG. 11.
  • Hydrocyclone 1110 aids in classifying solid particles exiting mill 904 by separating very fine particles from coarser particles.
  • recycling line 1112 can feed the particles directly back into mill 904, or can remove the particles completely from system 900.
  • recycling line 1112 is a tube or enclosed circuit, which transfers the particles to mill 904 or high pressure pump 902.
  • hydrocyclone 1110 is a dry type cyclone, located after spray dryer 908.
  • particles are dried in spray dryer 908 and gathered in collector 912.
  • the dry particles are introduced from collector 912 into cyclone 1110, where the particles are sorted according to size.
  • Cyclone 1110 operates substantially similar to the hydrocyclone described above, using a gas as the fluid in place of a fluid. Again, oversized particles are reintroduced into fluid energy mill 904 or high pressure pump 902 via recycling line 1112. Because gases normally have less surface tension than fluids, dry separation normally results in finer and more accurate size distribution.
  • hydrocyclone 1110 recycles the larger or more coarse fraction of material back to mill 904 for further size reduction, hydrocyclone 1110 assists in achieving a narrow size distribution of finished particles. Furthermore, hydrocyclone 1110 offers more intimate mixing of the particles and additives.

Abstract

L'invention concerne un moulin à G élevé dans lequel un disque de rotation tourne grâce à un axe à grande vitesse. Le matériel rentre dans des canaux du disque de rotation et en raison de la force centrifuge créée par la vitesse de rotation élevée, ce matériaux sort par une buse située à l'extrémité respective de chaque canal. Le matériau, qui sort de chaque buse à grande vitesse, est soumis à une force de cisaillement élevée, puis entre en collision contre un anneau. La force et l'impact de cisaillement contre l'anneau de collision font que le matériau se pulvérise, se désagglomère, et se densifie. Le matériau peut entrer dans le moulin dans un état sec, tel qu'une poudre sèche, ou mélangé à un fluide pour créer un phénomène similaire à une averse. Un système comprenant le moulin à G élevé peut également inclure un atomiseur et un hydrocyclone.
