Abstract
The invention relates to a device for the thermal or thermo-chemical treatment, more particularly calcination, of material (), more particularly battery cathode material (), comprising a housing (), in which a process space () is located. The material (), or carrying structures () loaded with the material (), can be conveyed in a conveying direction () into or through the process space () by means of a conveying system (). A process space atmosphere () prevailing in the process space () can be heated by means of a heating system (). There is a process gas system (), by means of which a process gas () can be fed to the process space (), said process gas being required for the thermal treatment of the material (). The process gas system () comprises a plurality of local injection units (), which are arranged and configured such that process gas () can be released in a targeted manner onto the material () or onto the carrying structures () loaded with material (), the process gas being released in a plurality of local process gas streams (), each having a main stream direction (). The invention also specifies a method for the thermal or thermo-chemical treatment of material (), in which process gas () is released in a targeted manner onto the material () or onto the carrying structures () loaded with material (), the process gas being released in a plurality of local process gas streams (), each having a main stream direction ().
