The embodiment of the application also discloses a production method of the ultramicro graphite.

The production method of the ultramicro graphite comprises the following steps:

s1, feeding the materials into a crushing classifier 1, and conveying the crushed materials into a cyclone separator 2;

s2, the material enters the cyclone separator 2 to be screened;

s3, feeding the screened materials into a bag type dust collector 3 along with air flow, and filtering the materials for collection;

and S4, collecting the filtered graphite.

The implementation principle of the production method of the ultramicro graphite in the embodiment of the application is as follows: during production, the materials are sent into the crushing and grading machine 1 to be crushed, after the materials are successfully crushed, the materials are fed into the cyclone separator 2 to be screened for proper material sizes, the materials enter the bag type dust remover 3 to be filtered through the filter bag of the bag type dust remover 3, the materials can be discharged from the discharge pipe 312 of the bag type dust remover 3, and the materials are collected.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
