A mixer assembly includes a first gearing mechanism and a second gearing mechanism. The first gearing mechanism has a driven shaft arranged as a hollow shaft, into which an adapter shaft is at least partly inserted and which is rotationally fixed to the driven shaft. The second gearing mechanism has a driven shaft arranged as a hollow shaft. The adapter shaft protrudes through the driven shaft of the second gearing mechanism. A first seal, e.g., a shaft seal ring, is plugged onto the driven shaft such that the seal lip of the seal contacts the driven shaft on a running surface formed on the driven shaft. The running surface is made of a second material and the rest of the driven shaft is made of a first material.

To provide a dispersing device that carries out an appropriate dispersion having a good yield, processing within an appropriate temperature range, and having a high power to disperse. The dispersing device disperses a mixture that is slurry or a liquid by causing the mixture to flow between a rotor and a stator toward the outer circumference by centrifugal force. It comprises a container, a cover assembly that closes an upper opening of the container, a stator that is fixed under the cover assembly, a rotor that is disposed to face the lower surface of the stator, a rotary shaft that rotates the rotor, a bearing that is located above the stator, and a spacer that is detachably disposed between the rotary shaft and the rotor to adjust a gap between the rotor and the stator.

An apparatus for producing a food product is disclosed. The apparatus comprises: an enclosed vessel for holding the food product, the vessel having a first end wall, a second end wall opposite to the first end wall, and a side wall between the first and second end walls; a first agitator rotatably mounted to the first end wall, the first agitator extending inside the vessel towards the second end wall; and a second agitator rotatably mounted to the second end wall, the second agitator extending inside the vessel towards the first end wall. The first agitator is unsupported by the second end wall, and the second agitator is unsupported by the first end wall.

Sensors employing elastomers enhanced with electrically conductive 2D nanoparticles are provided. The nanoparticles are formed by applying shear to layered materials present in elastomer precursors (e.g., elastomeric monomer(s) and/or curing agent(s)). Subsequent exfoliation of the layers occurs directly within the precursor and/or curing agent. The cured elastomer nanocomposites can be employed for electrochemical sensing, flexible touchpads, pressure sensors, and wireless sensors, amongst other applications.

The present application relates to a silicon-based negative electrode slurry, a preparation method therefor and a negative electrode piece. The preparation method comprises: (1) mixing CMC and a solvent to obtain a primary adhesive solution; (2) mixing PAA, a silicon-based negative electrode material, a conductive agent, a solvent, and the obtained adhesive solution, then performing double planetary mixing to obtain a secondary glue solution; (3) mixing a solvent and the obtained secondary adhesive solution to obtain a coarse slurry; and (4) mixing the SBR and the obtained coarse slurry to obtain a silicon-based negative electrode slurry. In the homogenization method of the present application, after the PAA and the SBR are incorporated in separate steps, a three-dimensional cross-linked network can be formed, good tensile behavior is exhibited, a bonding effect is improved, same can adapt well to volumetric expansion of silicon negative electrodes, and the cycling stability of silicon negative electrodes is improved.
