One option for the synthesis of cathode and anode materials is the so-called solid-state process. In this process route, the active material is created from the raw materials through a chemical transformation in suitable furnaces. Depending on the raw materials used, a wet grinding stage with dry pre-grinding processes can be required for the raw materials prior to the synthesis.
The CGS and s-Jet® fluidized bed jet mills can be used for the dry grinding. For the wet grinding, the Zeta, Neos or Zeta RS agitator bead mills are used, depending on the required target fineness. Synthesis via a furnace process can result in the formation of undesired agglomerates. In order to separate these, a dry dispersion with a CSM classifier mill is usually carried out after the synthesis furnace, without change of the original size and shape of primary particles.
