A continuous extrusion kneader comprising a first supply section for supplying a solid electrolyte, a first kneading section for kneading a material supplied from the first supply section to provide an intermediate mixture, a second supply section for supplying an electrode active material to the intermediate mixture, and a second kneading section for kneading the intermediate mixture and the material supplied from the second supply section, wherein the first kneading section comprises a forward kneading section for kneading the material supplied from the first supply section and conveying the material downstream, and a reverse kneading section for kneading the material supplied from the forward kneading section and applying a force in the upstream direction.

A co-rotating self-cleaning multi-screw extruder with a speed ratio of 2.5 and an extruding method therefor are disclosed. The screw mechanism includes a center screw and peripheral screws which rotate in the same direction. The peripheral screws are each of a double threaded structure, and the center screw is of a quintuple threaded structure. The rotation speed of the peripheral screws is 2.5 times that of the center screw, and the peripheral screws are always meshed with the center screw, whereas the adjacent peripheral screws are intermittently meshed with each other. The extruding method therefor is as follows: there is a periodically open space between adjacent peripheral screws, providing the periodical and intermittent mixing action, so that material from different thread grooves is mixed with each other. Meanwhile, the topological chaos action, by which the material is cut into two portions, is formed between the center screw and the peripheral screws, and the chaos mixing is caused by the random motion which is generated from the periodical changes of the channel, so that a periodical action of compression-expansion is achieved. Furthermore, due to the tensile force field action caused by the differences in rotation speed between the center screw and the peripheral screws, the compression preheating and dispersion mixing of the material are achieved. The co-rotating self-cleaning multi-screw extruder effectively improves the efficiency of conveying and mixing of materials.

The occurrence of separation or reaggregation is suppressed in a suspension such as a battery electrode slurry. A battery electrode slurry distributing apparatus includes: a circulation pipe via which a positive electrode slurry is to be circulated; and a control unit that controls the supply of the positive electrode slurry to each of coaters. In a period in which either the coater is allowed to receive the supply of the positive electrode slurry, the control unit inhibits the supply of the positive electrode slurry to the other coater. The circulation pipe is structured in a polygonal loop. The coaters are connected to respective elbow portions formed in the circulation pipe via the pipes, respectively.

A cutting edge for agricultural use provides opposed cutting edges arranged to be rotationally symmetric about an axis so that the cutting edge may be reversed in the field to repair or replace the cutting edge without the need for separate spare parts. In some embodiments a support plate may provide a ledge stop supporting the unused cutting edge to absorb impact shocks without cutting edge damage.

A mixing apparatus includes a first and a second feeding tube, a first and a second atomizing/refining dose control device, and a reaction chamber. The first and second feeding tubes are arranged in a multi-sleeves manner. The first and second atomizing/refining dose control devices are respectively disposed on terminal ends of the first and second feeding tubes. The reaction chamber accommodates the first and second feeding tubes and the first and second atomizing/refining dose control devices and has a liquid dose mixing wall. The first and second feeding tubes respectively receive a first and a second liquid dose. The first and second atomizing/refining dose control devices respectively atomize or refine the first and second liquid doses and spray the atomized or refined first and second liquid doses on a surface of the liquid dose mixing wall, so as to mix the first and second liquid doses.

Apparatus that mixes non-homogenous fluid. A threaded shaft within a housing circulates fluid within a container to effect mixing. In one embodiment, when placed in a container of fluid, the housing the fluid is recirculated through opposing ends of the housing. In an embodiment of a related method for mixing, a pump housing containing a screw journaled for rotation receives fluid within a container and conveys the fluid therethrough to circulate a fluid portion in the container along an exterior surface of the housing for mixing with another fluid portion to improve fluid homogeneity. After mixing, the portion of the fluid which first circulates through the housing may recirculate through the housing with said another portion of the fluid. The fluid may be continuously mixed and recirculated through the housing.

An apparatus can include a hollow tube, central shaft, agitation components, and bidirectional fluted auger. The hollow tube can have an inlet, outlet, and longitudinal central axis, and can facilitate the conveyance of foodstuff materials from the inlet to the outlet. The central shaft can extend along the longitudinal axis and can be rotationally driven both clockwise and counterclockwise. The agitation components can be coupled to the central shaft and can agitate and mix foodstuff materials being conveyed along the hollow tube. The bidirectional fluted auger can be coupled to the central shaft proximate the outlet, can rotate with the central shaft when the central shaft is rotationally driven, and can have a flow rate limiting inner cylinder, clockwise-progressing flute features, and counterclockwise-progressing flute features. The clockwise and counterclockwise progressing flute features can convey foodstuff materials toward the outlet when the bidirectional fluted auger is rotated clockwise or counterclockwise.
