A method of forming a composite material includes mixing granules of thermoplastic(s) and granules of reinforcing material(s) using a mixer with an interior friction coating. The friction generated by interaction between the granules and friction coating causes granules of at least one of the thermoplastic(s) to be heated to a liquid or semi-liquid state. The liquid/semi-liquid thermoplastic(s) act a binder for the mixed material. A system for forming such a composite material includes such a mixer with an interior friction coating. The system may also include a mould and/or a press for forming material produced by the mixer into a finished shape. The method and system may use post-consumer and post-industrial material as an input allowing such material to be recycled. In some cases, cross-contaminated or mixed post-consumer/post-industrial material may be recycled, potentially reducing environmental impacts.

The present invention discloses an integrated composite overload injection system and a working method thereof. The feeding mechanism preliminarily mixes water with a main agent and an auxiliary agent of an intelligent energy-gathered oil-displacing agent according to the ratio, the outlet of the feeding mechanism is communicated with the input port of the composite overload mechanism through a pipeline, the composite overload mechanism stirs, mixes, dissolves and overload ripens the preliminarily mixed solution to form mother solution, the mother solution is input from the output port of the composite overload mechanism to the inlet of the booster pump through a pipeline, the booster pump injects the boosted mother solution into the mixer, the mixer mixes the mother solution and the diluted high-pressure water and injects it into an oil-water well, and the power shafts of the composite overload mechanism and the booster pump are both driven by the driving mechanism.

A dynamic mixer dispense valve and metering apparatus suitable for use in mixing and applying high viscosity, disparate viscosity, high ratio, and/or relatively immiscible two part compounds that exhibit short cure times includes a housing supporting a pair of valve assemblies each coupled to respective sources of base and accelerator components. A pair of pneumatic valve actuators control the operation of the valve assemblies to control the flow of components into a mixing chamber. Within the mixing chamber a mixer impeller is rotatably supported and coupled to a source of rotational power. An additional pneumatic valve actuator combination operates a further flow control to prevent undesired material loss following a shot cycle.Note

The mobile unit comprises a water storage tank, at least one cement mixing barrel for mixing a cement slurry, a progressive cavity pump for pumping the cement slurry, and a hydraulic hose for connecting to a hydraulic power source to provide power to the cement mixing barrel and the progressive cavity pump. The mobile unit may also contain downhole tools needed for well abandonment, including a well cleaning tool, a cementing tool, a hydraulic packer, and more.

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 present invention relates to a vertical low-pressure reactor with stirred tank for leaching polymetal minerals and concentrates of lead, copper, zinc, iron and/or the mixtures thereof, in a solid-gas-liquid three-phase suspension system. The low-pressure vertical reactor with stirred tank consists of: a cylindrical vertical container with three or four deflectors equidistantly distributed across the 360°; a stirring system made up of two impellers coupled to a rotary shaft, that provides adequate reaction and interaction of the metal species of interest; a space of the volume of the reactor, corresponding to 20% to 35% of the total volume of the container, located at the top of the reactor and which acts as a gas chamber that provides a continuous feed of oxygen; and a system of coils placed on the outside or inside surface of the reactor to ensure efficient heat-transfer reactions and controlled kinetics.

A mixing system for mixing a liquid includes a first impeller segment having a first mount and a first mixing blade secured to the first mount and a second impeller segment having a second mount and a first mixing blade secured to the second mount, the second impeller segment being separate and discrete from the first impeller segment.
