▎ 摘　　要

NOVELTY - The method involves taking natural flake graphite or artificial graphite as raw material, adding an oxidant to carry out oxidation reaction to prepare graphite oxide, and adding an intercalating agent to carry out intercalation reaction. The reaction solution is subjected to suction filtration after the intercalation reaction is completed, and the filtered solid is washed to neutrality and dried to obtain intercalated graphite after drying. The grinding device is used to grind and sieve the described oven-dried intercalated graphite prepared to obtain graphene particles. The obtained graphene particles are collected and stored to use a quantitative collection mechanism to quantitatively collect the collected and stored graphene particles and use a packaging machine for packaging. The quantitative collection mechanism includes a conveying roller (2) rotatably installed between two adjacent fixed frames. USE - Graphene particle production and processing based-quantitative collection process used in field of materials science, micro-nano processing, energy, biomedicine, and drug delivery. ADVANTAGE - The graphene particles after the quantitative can automatically discharge, without manual intervention, saves the labor cost and improves the working efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a partial structure of the quantitative collection mechanism.
