FJM series grading mechanical mill is suitable for the depolymerization of loose agglomerated materials; It is more efficient and consumes less energy.

Development requirements - to reduce the fine powder content in the depolymerization process of lithium cathode materials.

The raw material is sent into the ceramic guide ring of the main engine along the tangent direction of the cylinder wall through the gas. The raw material is separated from the qualified fine powder by the classifying rotor first, and the remaining coarse powder is dropped to the crushing area for depolymerization and crushing. So as to effectively reduce the fine powder content in the product, a greater limit to prevent the occurrence of over crushing.
