    摘要: Provided is a method for producing metal microparticles in which the ratio of crystallite diameter to the particle diameter of the metal microparticles is controlled. At least two types of fluid to be processed are used, including a metal fluid in which a metal or a metal compound is dissolved in a solvent, and a reducing agent fluid which includes a reducing agent. Sulfate ions are included in one or both of the metal fluid and the reducing agent fluid. The fluid to be processed is mixed in a thin film fluid formed between at least two processing surfaces, at least one of which rotates relative to the other, and which are disposed facing each other and capable of approaching and separating from each other, and metal microparticles are precipitated. The present invention is characterized in that at this time, the ratio (d/D) of the crystallite diameter (d) of the metal microparticles to the particle diameter (D) of the metal microparticles is controlled by controlling the molar ratio of metal and sulfate ions in the mixed fluid to be processed.

    摘要: A hinge dampening device is provided for a granulation processor having a bowl and a lid. A dampening device includes first and second spaced apart hinge supports fixed to the bowl and a pin extending through the lid collar residing between the hinge supports. The first end of the pin is fixed to the first hinge support, and a second end of the pin extends through the second hinge support. An adjustable compressive force is applied axially to the hinge supports and lid collar to create frictional resistance to rotation of the lid. The rotational resistance provides controlled opening and closing of the lid.

    摘要: The invention relates to the granulation by agglomeration of ceramic compositions ground in dry phase. The invention proposes an alternative to the method of wet-phase grinding and drying by atomization. The method consists of dry-phase grinding and preparing argillaceous ceramic compositions without binders, additives, or deflocculants from argillaceous minerals (about 60%) mixed with inorganic materials, grain sizes of less than 120 micrometers, in a horizontal rotary cylindrical device with deflecting paddles, the intake of said minerals, powdery materials and water takes place at one end of said device; and granules that are moved by said deflecting paddles are formed due to the rotation of said device. The outlet of the granulated material is at the opposite end of said device. The invention offers the following advantages: energy savings of 80%; savings in water consumption during granulation of 75-80% and 10-20% of additional savings in the pressure for pressing the granules. The time necessary to change from one ceramic composition to another is one hour, compared with several days using the current method of atomization. The method of granulation constitutes a novel environmental technology with zero air and water table pollution, and with much lower water consumption.
