Description

Technical Field

[0001] The utility model relates to the technical field of graphite electrode production, in particular to a raw material mixing device for graphite anode production. Background Art

[0002] Graphite electrode refers to a high-temperature resistant graphite conductive material made of petroleum coke and asphalt coke as aggregates and coal tar as binder, through raw material calcination, crushing and grinding, batching, kneading, molding, roasting, impregnation, graphitization and mechanical processing. It is called artificial graphite electrode (referred to as graphite electrode), to distinguish it from natural graphite electrode made from natural graphite as raw material.

[0003] During the production process of graphite electrodes, the raw materials need to be mixed in a certain ratio. Since most graphite raw materials are powders, when the raw materials are mixed by traditional stirring devices, it is very easy for the raw materials to be broken and unable to be fully mixed, which in turn causes the conductivity of the graphite electrode to be seriously affected.
