Abstract: A computing system may include a digital material collaboration engine configured to construct a digital material that is partially-defined based on input from a requestor entity of a digital material collaboration platform. The digital material may be for the manufacture of a physical product and may be partially-defined to include a physical material or product requirements for the physical product, but does not define process parameters of a manufacturing process to manufacture the physical product. The digital material collaboration engine may further be configured to receive, from provider entities of the digital material collaboration platform, proposed versions for the digital material that specify process parameters for the manufacturing process, and connect the requestor entity with a selected provider entity of the provider entities of the digital material collaboration platform based on a particular proposed version for the digital material provided by the selected provider entity.

Abstract: Conveyed goods of grains are fed from a pressure vessel into a conveyor line at a feed point for conveyance to a discharge point for supply to an extrusion head. The goods are plasticized in the extrusion head and extruded in a punctiform manner via a nozzle of the extrusion head. The extrusion head is moved dynamically by a manipulator during extrusion of the plasticized goods. Conveyor gas is force into the conveyor line by a gas compressor and allowed to escape the conveyor line at a separation point in a region of the discharge point. A gas positive pressure is temporarily applied by the gas compressor to the pressure vessel as the goods are fed from the pressure vessel into the conveyor line while bypassing the conveyor line via a first valve and closing a second valve in the conveyor line between the feed point and the gas compressor.

Abstract: A defined mineral phase is separated from a ground ore having several chemical phases and being present in a heterogeneous particle size distribution by classifying the ore according to a defined particle diameter into at least two fractions, a first fraction having particles essentially larger than the defined particle diameter and a second fraction having particles essentially smaller than the defined particle diameter, and the defined mineral particles of value being present in both fractions, floating the first fraction having the greater particle diameters and selecting the defined mineral particles of value in a flotation concentrate, selectively admixing the defined mineral particles of value in the fraction having the smaller particle diameters with magnetizable particles, applying a magnetic separation process to the second fraction having smaller particle diameters, and separating a concentrate with an enrichment of the defined mineral phase of value.

Abstract: The invention relates to a method and devices for separating primary ore into dead rock and at least one type of rock which contains at least one valuable mineral, the at least one valuable mineral comprising at least one rare-earth mineral. A sensor-controlled pre-framing method, which is based on the identification and classification of individual rock particles, is used.

Abstract: A specified geometry of a dispersion nozzle is adapted for a required size distribution of a phase dispersed in a dispersing phase by calculating a shear stress rate S and a relative velocity v0 between phases; determining at least one local maximum stable radius for the dispersed phase using values obtained from Rb=(2?/Cs?LSv0)1/2, where ? indicates surface tension of the dispersed phase, Cs indicates the coefficient of friction of the dispersed phase in the dispersing phase, and ?L indicates density of the dispersing phase; determining the distribution of the local maximum stable radius over a cross-sectional area of the dispersion nozzle; and, if a specified maximum stable radius is exceeded in at least one region of the cross-sectional area, changing the geometry of the dispersion nozzle such that a higher shear stress rate S and/or a higher relative velocity v0 of the phases is achieved at least in some regions.
