▎ 摘　　要

NOVELTY - The crusher has a collecting box (1) whose front and rear edges of a lower end surface are fixedly connected with a supporting block (12). A lower end of the supporting block is slidingly connected to a telescopic column (14). A bottom plate (15) is fixed on a lower surface of the telescopic post. A screw thread (16) is connected in a middle of an upper end surface of a bottom plate. An inner side of the screw thread is fixed with a screw thread rod (17). A fixing block (2), an airflow crusher main body (7), a connecting pipe (6) and a fan (5) are fixed on an end of a connection pipe far away from the main body of the airflow pulverizer. USE - Airflow crusher for preparing graphene used in micro-nano processing, energy, biomedicine and drug delivery applications. ADVANTAGE - The easy-to-maintain graphene prepared by using sieve plate for shaking and sieving the graphene raw material after finishing, by the fan is not in accordance with the specification graphene the raw material for extracting, and then by using the connecting pipe to the non-standard of the material graphene the airflow crusher main body inner cavity for crushing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the method for preparing graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of an airflow crusher. 1Collecting box 2Fixing block 3Control screen 4Material extracting pipe 5Fan 6Connecting pipe 7Airflow crusher main body 12Supporting block 14Telescopic column 15Bottom plate 21Drawer 35Handle
