The invention relates to the technical field of
graphite processing, in particular to a
natural graphite material
processing and grading device which comprises a grading mechanism, the grading mechanism comprises a grading
machine shell, the upper end of the grading
machine shell is fixedly connected with a motor, the movable end of the motor is fixedly connected with a grading
turbine, the grading
turbine is located in the grading
machine shell, and the grading machine shell is fixedly connected with the grading mechanism. A feeding
pipe is fixedly connected to the lower portion of the side wall of the classifier shell. The arrangement height of the grading mechanism is far higher than that of a traditional vortex
airflow grading mechanism, in the process that
natural graphite materials are conveyed along with
wind power, the materials with the large
specific gravity sink to the inner wall of the grading machine shell due to the
gravity effect and flow out through the discharging
pipe, the pneumatic force of the light materials is larger than the borne gravity, the light materials are further graded through the grading
turbine, and the grading efficiency is improved. And the graded
fine powder is taken out of the shell of the grading machine, and materials are centrifuged into the shell of the grading machine, so that the purposes of improving the grading treatment capacity and improving the grading precision are achieved.
