Methods, systems, and computer storage media for providing an overflow management configuration for a material processing system that blends a material from multiple sources. The overflow management configuration identifies an arrangement of components and settings of the components in the material processing system to support blending a material while reducing a risk of overflow. The blending flow configuration can support optimizing outcomes of different types of downstream processes. The material properties data are identified based on different types of measurements. For example, block models, lab assays, and on-stream analyzers can be used to determine composition of the material. Grinding line performance data that estimates the grinding line performance or capacity can also be accessed. A description of a conveyance network design of the material processing system is generated. The conveyance network design can specifically help identify source nodes, sink nodes, transshipments nodes, and network arcs of the material processing system.

In accordance with presently disclosed embodiments, systems and methods for efficiently handling dry additives to be mixed with bulk material in a blender are provided. The systems may include a support structure used to direct bulk material from one or more portable containers on the support structure to a first outlet location, and a combined metering/transferring system for directing dry additives from another portable container to a second outlet location. Specifically, the metering/transferring system may output a metered flow of dry additives to the blender mixer to be combined with bulk material that is released from the portable containers. The metering/transferring system may utilize a gravity feed outlet coupled to a metered screw or other conveying device to move the dry additive from the portable container to the second outlet location.

A powder mixing system and method improves productivity of a final product by reducing time required for completion of mixing. The powder mixing system includes a mixing vessel provided with a rotating shaft for mixing multiple kinds of powder, a rotating machine for rotating the mixing vessel by means of the rotating shaft, an image photographing device for acquiring an image of the powder in a mixing process, and a computer. The mixing vessel includes a window through which the image of the powder is photographed. The computer has a function of detecting that the mixing vessel is located at a predetermined position. The image photographing device acquires the image of the powder through the window of the mixing vessel located at the predetermined position. The computer estimates a mixing state of the powder based on the acquired image of the powder.

Disclosed are a stirring process and a stirring system for a neodymium-iron-boron powder and a process for manufacturing a neodymium-iron-boron magnetic steel. The stirring process for the neodymium-iron-boron powder mainly comprises the following aeration, feeding and stirring. Specifically, the aeration refers to filling a mixer with nitrogen and/or an inert gas, with the internal space of the mixer closed; the feeding refers to placing a neodymium-iron-boron powder to be stirred into the mixer and keeping the internal space of the mixer closed; and the stirring refers to introducing the mixer with a pulsed air stream, which is an intermittently jetted air stream formed by nitrogen and/or an inert gas, and by which the neodymium-iron-boron powder can be repeatedly blown up and down to mix and stir the neodymium-iron-boron powder.

A mixing device serves for producing a powder mixture of a first powder component and at least one second powder component for an additive manufacturing device. The mixing device includes a first container for receiving the first and/or the second powder component, where a discharge opening for discharging the first and/or the second powder component is provided at a lower boundary of the first container, and a second container for receiving the first and/or the second powder component. The second container is designed to be at least partially open towards an upper side. The first and second container each include at least one fluidization zone for introducing a gas into the first and second container. The mixing device further includes a powder conduit that connects to the discharge opening of the first container and is guided into the second container.

A bulk cargo blending hopper has a hollow interior volume that is selectively communicated with a source of vacuum pressure. A first conduit has a first end that is connected to the housing of the hopper and communicates with the interior volume of the housing of the hopper. An opposite second end of the first conduit is configured for communication with a source of bulk cargo that is separate from the hopper. A second conduit has a first end that is also connected to a portion of the housing of the hopper and communicates with the interior portion of the housing. A second end of the second conduit is also connected to a portion of the housing of the hopper and communicates with the interior volume of the housing of the hopper.

A molded product production system includes a powdery material mixing and feeding device configured to feed mixed powdery materials including at least two types of powdery materials, a filler configured to fill, with the mixed powdery materials fed by the powdery material mixing and feeding device, a die bore of a compression-molding machine, a sensor configured to measure a mixing degree of the mixed powdery materials fed by the powdery material mixing and feeding device, and a molded product removal mechanism configured to distinguish a molded product obtained by compression molding mixed powdery materials having a mixing degree measured by the sensor out of a predetermined range from a molded product obtained by compression molding mixed powdery materials having a mixing degree within the predetermined range.

A powdery material mixing degree measurement device includes a discharger configured to discharge mixed powdery materials to a filler configured to fill, with the powdery materials, a vertically penetrating die bore of a compression-molding machine including a table including the die bore, a slidable lower punch including an upper end inserted to the die bore, and a slidable upper punch including a lower end inserted to the die bore, a plurality of movable portions configured to move the mixed powdery materials to the discharger, and a sensor configured to measure a mixing degree of the mixed powdery materials in the movable portions.

A system for preparing recipes with components coming from closed containers (S1-S5) provides for using one or more robotic units (1), each of which withdraws a selected container, arranging a plurality of hoppers (7.1-7.5), in each of which the withdrawn selected container is inserted by the robotic unit (1), and in each of which the container is automatically opened for loading the component into the hopper (7), discharging a preset component dose from each hopper (7), and collecting the dosed components for preparing the required recipe; a driving and control unit (15) provides for driving and controlling all of these operations as a function of the required recipe. Thereby, an automatic system for preparing recipes is achieved, which is fast, with a low processing cost, and free from risks related to the processing.
