摘要:
Method and device for preparing a paste by blending or mixing materials, in particular for making aluminum production electrodes. The method includes the following operations: a) introducing the materials to be blended or mixed into a vat (31) having an inner surface extending along a substantially horizontal axis of revolution (X), b) rotating the vat (31) about the axis of revolution (X) and urging the materials via centrifugation against the inner surface of the vat (31), and c) locally dislodging the centrifuged materials from the inner surface by rotating the vat (31) and causing same to fall onto a crumbling tool (40).
摘要:
A method of making hot mix asphalt using recycled asphalt in which tertiary air is mixed with products of combustion at an exit of a refractory-lined chamber to produce hot controlled temperature process air, the temperature of the tertiary air being increased while the temperature of the products of combustion is decreased to adjust a temperature of the hot controlled temperature process air. Particles of the recycled asphalt are heated by exposing the particles to the hot controlled temperature process air in the rotary counter-flow dryer and mixer and moisture is removed from the recycled asphalt with the hot controlled temperature process air.

A gyroscopic rotational monitoring system may be utilized for monitoring one or more properties of rotatable container or vessel, and/or one or more properties of a displaceable material contained in the rotatable vessels. An exemplary aspect relates to the use of a gyroscope and periodicity sensor (e.g., accelerometer) to determine rotational speed of a concrete mixing drum, so that the slump or other property of the concrete can be monitored or adjusted such as by dosing with water, chemical admixtures, or mixture thereof.

A mixer 1 for thermal treatment of a material for mixing consisting of solid particles comprises a mixing vessel 2 for admitting the material for mixing. The vessel 2 has at least one thermal medium channel that with its surface gets at least partially in contact with the solid particles to be heat-treated, through which thermal treatment media are fed when the mixer 1 is in operation. Additionally, the mixer 1 has available a device for circulating the material for mixing found in the container 2. The container 2 is turnably supported about an axis R that penetrates the two front sides 7, 20. A motorized drive 17, 18, 18.1 serves as a circulating device to turn the container 2.
摘要:
A mixer for insertion into a rotor of a centrifuge has a mixing trough and an obstacle device with at least one obstacle. The at least one obstacle is configured in order to influence the flow of a liquid present in the mixing trough. In response to a rotation of the rotor, with a specified incorporation of the mixer in a holder of the rotor, a spacing between at least one wall section of the mixing trough and the obstacle device is variable such that the liquid present in the mixing trough flows around the obstacle of the obstacle device.
摘要:
A pressure vessel and a drum rotatably arranged inside which has an inner space for material that is introduced into the pressure vessel. In various embodiments, a drive mechanism rotates the drum in relation to the pressure vessel. The drive mechanism can include a motor that can be located inside the pressure vessel in an interspace between the drum and the pressure vessel. Some embodiments include a door to close an opening of the pressure vessel and a part of the door can extend into an open end of the drum when the door is closed to keep the material in the drum and out of the interspace. In particular embodiments, a steam supply conduit extends into the drum at the closed end of the pressure vessel. In some embodiments, a helical agitation blade in the drum moves the material away from or toward the opening.
摘要:
A fomite tumbler and method of transferring an agent from a source object to one or more fomites is provided. The tumbler provides reproducible and adjustable experimental determination of agent transfer between objects such as during handling. The inventions provide a unique mechanism for studying the transfer of a biological agent through a public use system such as the United States Postal System.
摘要:
A horizontal mixer (50) is disclosed. Multiple blades (92) are affixed to and rotate with a tumbler (80) of the mixer (50). These blades (92) extend within an interior mixing chamber (90) and are center-angled so as to promote a desirable mixing action within this chamber (90) (e.g. so as to fold a slurry within the chamber (90) onto itself). One characterization is that the blades (92) are oriented so as to direct a flow toward a common outlet region (78) within the tumbler (80) throughout at least a certain rotational angle. The mixer (50) is particularly suited for realizing a desirable homogeneity of particles within a slurry from which radioisotopes may be produced.
摘要:
A mixing fin assembly adapted to mix and guide materials in a rotatable mixing drum of a type used in a transit concrete mixing vehicle includes a spiral mixing fin designed to extend transversely into the drum constructed of a lightweight, moldable polymeric material which is flexible and resistant to abrasion, the mixing fin includes a plurality of conjoined sections that are fit together, preferably utilizing fin locking tabs and mating fin locking sockets. A preferred way of mounting the mixing fin into mixing drums uses a spiral fin mount rail track adapted to be fixed to the interior surface of the mixing drum. A locking tab locks the upper part of the rail track into the fin structure.
