  • Patent number: 9555473
    Abstract: An apparatus for increasing the bulk density of metal powder may include a sealed chamber, a nozzle, and a target. The sealed chamber may include an inert environment. The nozzle may be coupled to an inert gas source and may be configured to introduce raw metal powder into a flow of the inert gas for discharge as a cold spray mixture of the raw metal powder and the inert gas into the chamber. The target may be housed within the sealed chamber and may be configured to receive an impact of the cold spray mixture. The nozzle and the target may be configured to flatten the raw metal particles into flattened metal particles in response to the cold spray mixture impacting the target.

  • Patent number: 9440236
    Abstract: The invention concerns a method and an arrangement for the output of mineral material from a drum mill having a horizontal rotation axis, a sieving wall at its end wall, material can leave through the sieving openings in to pulp-lifting chambers, limited by the sieving wall, the end wall, a limiting wall, and limiting walls that lead towards an output cone, whereby material in the pulp-lifting chamber is emptied down towards the output cone when the pulp-lifting chamber is an upper part of a revolution. In order to increase the rate of revolution, material that does not reach the material output cone is collected in a material collection pocket which carry the material at a level radially closer to the rotation axis than the inner limiting wall, whereby collected mineral material leaves the material collection pocket during, a subsequent revolution.

  • Patent number: 9420916
    Abstract: A nut chopper includes an upper hopper, a lower container, and a grate positioned between the hopper and container. A series of parallel blades supported on an axle and coupled to a crank is positioned so that the blades may be rotated through the grate. As the blades pass through the grate, they chop the nuts that are in the path of the blades. Once individual nuts are chopped into sizes that are smaller than the width of the openings formed in the grate, the chopped portions will fall through the grate and into the container.

    Abstract: A method for dispersing a filler having high agglomerating properties in a resin and a micro-dispersing mixer used in the method are provided. Further, a method for producing a sealing material that can avoid a defect caused by agglomerates of a filler (for example, carbon black) in an electronic material such as a semiconductor package, a masterbatch resin produced by the method, and a micro-dispersing mixer used in the method are provided. When a filler is dispersed in a molten resin composition to produce a filler-dispersed molten resin composition, a resin composition containing filler aggregates and a molten resin composition is preliminarily mixed by a mixing means, and, thereafter, the preliminarily mixed mixture is allowed to pass through the micro-dispersing mixer with a fine flow path to disperse the filler in a filler resin composition.

    Abstract: A disc mill includes an inlet configured to provide solid material for grinding to the grind plates in a smooth and constant manner. A solid ring is added around an outer circumference of the grind plates to control the grinded solid discharge rate. In some embodiments, the grind plates are configured with constant solid path way open area from row to row. The grind surface and solid pass way open area are maximized by increasing the relative tooth height compared to the tooth width. The teeth can be positioned according to a block channel configurations so as to force the solid material to pass along the grind surface of each row. A grind plate design program is used to enable conjunction of the design parameters with application variation, thereby enabling the optimum grind plate design to meeting various applications needed.

  • Publication number: 20130082130
    Abstract: An apparatus is disclosed for containing a material, such as coffee beans, that may be used with a grinding apparatus. The apparatus may have a directing component to guide a controlled dose of material toward the grinding apparatus. In one embodiment, the apparatus comprises a container with a base portion that engages a grinding apparatus. The container, when engaged with the grinding apparatus, can direct coffee beans toward the grinding apparatus and has a door that releases a controlled dose of beans. A grinding apparatus is also disclosed that may have a movable tongue to cause excess grounds caught on interior components of the grinding apparatus to exit the grinding apparatus. The apparatus, systems, and methods reduce labor associated with grinding the material and allow a user, such as a barista, to more efficiently prepare brewed beverages, such as single-cup portions of coffee.

  • Publication number: 20120325950
    Abstract: A shredder includes a rotor supporting a plurality of multi-point cutters that mesh with a counter-knife having generally V-shaped grooves. Each cutter has at least one corner defined by an intersection between two contiguous side faces of the body of the cutter. The corner defines a plurality of cutting points spaced apart along a first direction. The cutters are mounted on the outer peripheral surface of the rotor such that the first direction of each cutter is substantially tangent to the outer peripheral surface, and such that the corners of the cutters mesh with respective V-shaped grooves in the counter-knife as the rotor rotates about its axis. The multiple points of each cutter encounter and mesh with the groove in the counter-knife in a sequential fashion.

  • Patent number: 8308096
    Abstract: An article in the form of one of a plate, a sheet, a cylinder, and a portion of a cylinder, which is adapted for use as at least a portion of a wear resistant working surface of a roll is disclosed. The article includes a metal matrix composite comprising a plurality of inorganic particles dispersed in a matrix material. The matrix material includes at least one of a metal and a metal alloy, wherein the melting temperature of the inorganic particles is greater than the melting temperature of the matrix material. A plurality of hard elements are embedded in the metal matrix composite. The wear resistance of the metal matrix composite is less than the wear resistance of the hard elements, and the metal matrix composite preferentially wears away when the article is in use, thereby providing or preserving gaps between each of the plurality of hard elements at a working surface of the article.

  • Publication number: 20120205474
    Abstract: A grinding apparatus for dispensing a dose of ground frozen material starting from a frozen block. The apparatus comprises a grinding unit, for grinding the frozen block in order to provide an amount of ground frozen material and a feeding unit for feeding the frozen block to the grinding unit. In particular, the feeding unit comprises a feeding member that is adapted for moving frozen block for a desired predetermined grinding stroke against grinding unit such that a grinding length of block is ground. A grinding unit provides at least one grater and one motor for causing the grater to rotate. In order to obtain a desired weight of the dose, a volume of frozen material is calculated that corresponds to said weight, since the density of the frozen material is known.
