Process for mixing and cooling electrode material

摘要

A mixture which is used for the manufacture of electrodes and comprises dry material and electrode binding agent. The mixture is prepared in a system which is at least in part dust and gastight and such that the mixture is simultaneously stirred up or fluidized, degassed and homogenized, and treated thermally. In the course of such treatment further additions can be made to the mixture. The described procedure takes place mainly in mixers operating continuously or discontinuously, various arrangements and designs of mixer being possible. Fundamental to the thermal treatment is that the mixture can be cooled in a mixer such that the coolant vaporizes completely during the mixing. The thermal treatment is regulated by way of given operational parameters.
