A method for operating a mixing apparatus of a manufacturing plant comprises supplying multiple powdered products to the mixing apparatus. An inlet mass flow rate of the multiple powdered products into the mixing apparatus and a weight of the multiple powdered products in the mixing apparatus are measured. The multiple powdered products in the mixing apparatus are mixed to form a mixed product. The weight of the multiple powdered products in the mixing apparatus and an outlet mass flow rate of the mixed product from the mixing apparatus are predicted based on the measured inlet mass flow of the multiple powdered products. The predicted outlet mass flow rate of the mixed product from the mixing apparatus is corrected based on the measured weight of the multiple powdered products in the mixing apparatus. The mixed product is processed into final products

In accordance with presently disclosed embodiments, systems and methods for efficiently managing bulk material are provided. The disclosure is directed to systems and methods for efficiently combining additives into bulk material being transferred about a job site. The systems may include a support structure used to receive one or more portable containers of bulk material, and a mulling device disposed beneath the support structure to provide bulk material treatment capabilities. Specifically, the mulling device may facilitate mixing of coatings or other additives with bulk material that is released from the portable containers, as well as transfer of the mixture to an outlet location.

The stirring barrel is positioned under the storage tank, the bottom center of the stirring barrel is fixedly connected to a stationary shaft, the stirring barrel is rotationally drivable to rotate together with the stationary shaft about the axis of the stationary shaft, the stationary shaft extends upward into the storage tank, a sleeve is provided on an outer side of the stationary shaft, the sleeve is rotatably connected to the stationary shaft, so that the stirring barrel rotates relative to the storage tank; a portion of the sleeve accommodated in the stirring barrel is fixedly connected with a stirring part, an upper end of the stationary shaft is fixedly connected with a connecting plate.

The application relates to a raw material mixing apparatus, including mixing drums and a feed pipe, each of the two mixing drums is provided with a feed port and a discharge port, the feed ports of the two mixing drums are both communicated with the feed pipe, and a switching valve is arranged on the feed pipe; a first rotating disc and a second rotating disc are rotatably connected at two ends of the mixing drum respectively, and a stirring assembly is connected between the first rotating disc and the second rotating disc in the axial direction of the mixing drum; the stirring assembly includes a central stirring element and a plurality of non-central stirring elements radially arranged between inner side walls of the mixing drums and outer side walls of the central stirring element.

A conveyor having a conveyance structure, mixing components, belt, and gas manifold. The gas manifold disposed within or on an exterior portion of the structure. The gas manifold having one or more manifold outlet ports to dry, condition, or treat a metered stream of seed within the conveyor. The manifold may be operably connected to a recirculating air system providing the vacuum source and pressurized air source of atmospheric or conditioned air. A filter and vacuum port may extract debris or humidity from the metered stream of seed within the conveyor. A plurality of mixing baffles may be longitudinally spaced apart through the conveyor in a laterally alternating manner to mix the metered stream of seed. The conveyor may be used to transfer, mix, dry, condition and treat the metered stream of seed between multiple stages of treatment.

A stirring device for a powder tank of an apparatus for manufacturing a three-dimensional object. The stirring device is configured to rotate within the powder tank about an axis of rotation, and comprises a base plate and a strut. The strut extends from the base plate and is arranged to extend into the powder tank forming an obtuse angle with the outer edge of the base plate

The invention relates to a process of manufacturing a dental milling block with a homogeneous color and/or translucency gradient. This process comprises the steps of providing a mold with a cavity having a z-direction and an x/y-direction, filling the cavity partially with a first powder up to a height H1, the first powder having a volume VP1 with a top and bottom surface, introducing a second powder on top of the first powder up to a height H2, the second powder having a volume VP2 with a top and bottom surface and, the top surface of the first powder being in contact with the bottom surface of the second powder and forming an intermediate region, providing a mixer unit with at least one rotatable mixing element, introducing the rotating mixing element in z-direction into the intermediate region, mixing the powder located in the intermediate region by rotating the mixing element, removing the rotating mixing element from the powder, compacting the powder, optionally applying heat to the compacted powder, the first powder differing from the second powder by its physical properties and/or chemical composition and/or color. The invention also relates to a process of producing a dental restoration using dental milling block obtainable according to this process.
