▎ 摘　　要

NOVELTY - The method involves collecting and hermetically storing a graphene raw material. Impurities are cleaned and filtered in the graphene raw material before extracting a graphene component. The graphene raw material is poured into a grinding extraction device for grinding. Blocking and scraping processes are performed when the graphene raw material is blocked after grinding. Ground particles are fed into a centrifugal extraction device for centrifugal extraction and purification. The purified liquid containing the graphene component is allowed to flow into an evaporation device for evaporation and crystallization. The bolts are removed. A container containing crystal is hooked by using a hook-shaped tool. The crystal is scraped by using a scraper (7111) to collect the crystal. USE - Method for producing graphene grinding raw material by using a through-blocking device. ADVANTAGE - The method enables solving problem that a grinding barrel is easy to be blocked, and a barrel wall is easily to stick a large amount of wet graphene raw material, so that the graphene is convenient to take off after crystallization. The method enables using a scraping assembly and the through blocking device to work at same time so as to greatly improve working efficiency, so that the grinding barrel is avoided to split and manually plug, thus improving efficiency of a plug. The grinding barrel has strong practicability. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a grinding barrel.
