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).

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.

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.

The subject matter of this specification can be embodied in, among other things, a rotary mixer with a housing defining a mixing chamber defining a rotation axis, the housing being rotatable about the rotation axis in a rotation direction and having a longitudinal midpoint, a set of blades within the housing, wherein at least one pair of blades of the set of blades forms an angle with respect to each other, and at least one blade of the set of blades is shorter than another blade of the set of blades in the rotation direction, and a splitter blade located within the housing with respect to the longitudinal midpoint and the angle to divide material in the mixing chamber between the at least one blade of the set of blades and the other blade of the set of blades, as the cylindrical housing is rotated about the rotation axis.

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.

A slurry dispensing system is disclosed. A peristaltic pump may direct a flow of slurry out of a horizontal mixer to a slurry dispenser. This slurry dispenser may be operated on a programmed manner by a controller to dispense slurry into a container. Both a bypass valve and a dispensing valve of the slurry dispenser may be opened/closed on a programmed basis by the controller to deliver slurry to a container, such as a glass column. Slurry may be intermittently directed into a metering chamber of the slurry dispenser, while the remainder of the slurry being directed into the slurry dispenser may be recirculated back to the horizontal mixer.

The present invention relates to a mixer with a drum that comprises a mantle, a bottom and a top and which rotates around an axis of rotation.

An improved blending apparatus for manufactured wood products with a rotating blending drum or cylinder with a pattern of alternating flights of different configurations extending from the interior of the drum. The flights lift the strands as the drum rotates to different heights before the strands free-fall back to the bottom of the drum. One flight is shorter, and may be trapezoidal in cross-section. The second flight is taller, and may have a bull-nose configuration with substantially vertical sides. During operation, the design of the bull-nose flight tends to hold more strands and to carry them closer to the top of the drum before the strands drop and fall. In contrast, the shorter height and angled sides of the trapezoidal flight tends to hold fewer strands and to not carry them as high along the side before strands drop and fall. The alternating pattern causes a more consistent and dispersed fall of strands as the drum rotates, resulting in a significantly larger and more consistent amount of the sprayed adhesives and waxes being applied to the strands, and not passing through gaps to build up on the drum wall.
