A stirring device for wastewater includes a drive device having a drive shaft extending vertically in the assembled state, a stirring body mounted on the drive shaft, a safety bearing in which a free end of the drive shaft is rotatably held, a slide sleeve is mounted on the free end of the drive shaft, and a device for detecting a state of wear of the slide sleeve. The device for detecting the state of wear includes a sensor mounted on the safety bearing and an evaluation device for evaluating the signals delivered by the sensor.

A method and apparatus for operating a stirring mechanism for a container which is filled with a medium, wherein a value for the rotation speed of the stirring mechanism, which is predetermined for operating the stirring mechanism with a low level of energy consumption and stored in a memory, is set by an actuation and evaluation device such that reduced energy consumption by the stirring mechanism is achieved while at the same time the medium is thoroughly mixed.

Disclosed is a candle making apparatus including an electric appliance for a process of sequentially melting, mixing and holding the constituents of a container candle inside a jug and at a molten temperature until a user is ready to pour the melt into a container. Typically the constituents of such candles include vegetable wax, soy products, vegetable oils, fats or fatty acids. They are melted at a higher temperature, then mixed, and cooled so that volatile ingredients can be added at a lower temperature while the mixture remains melted, and is further stirred. The process is controlled by a microprocessor. A visual interface displays progress and accepts user input.

A conductive auxiliary agent for an electrode slurry for a battery. The electrode slurry contains an electrode active material and a conductive auxiliary agent, and is applied to a sheet-shaped current collector. The conductive auxiliary agent is a carbon paste produced by dispersing a carbon powder in a solvent. The carbon paste has a viscosity of at least 20 Pa.Math.s and not more than 40 Pa.Math.s. The carbon material can be acetylene black.

The invention relates to a method and a bioreactor for drying biogenic residues to a dry mass comprising filling the residues into a bioreactor filled with spheres and mixing the spheres and the residues so that films of the residues form on the surfaces of the spheres, drying the films of residues with the formation of crusts of dry mass with a residual water content on the surfaces of the spheres by feeding a drying medium into the bioreactor,

grinding and further drying the dry mass by mixing and grinding off powdery dry mass from the spheres.

The present invention relates to a magnetic mixer capable of minimizing mixing of foreign substances, which are generated in components of the magnetic mixer, of a liquid to be mixed, having a simple structure for cleansing a structure supporting an impeller shaft, and capable of securing a sufficient output when a large-scale mixing system with an impeller shaft is configured; and a mixing system including the same.
