▎ 摘　　要

NOVELTY - The device has a mixed material feeding hopper (1) and a steel-powder feeding hopper (2) connected with an airflow crusher (3) i.e. jet mill. A cyclone separator (4) and the airflow crusher are formed with discharging openings that are fixed with a pipeline. A recycling chamber (5) is connected with a lower part of the cyclone separator. A pulse filter (6) is connected with the cyclone separator that is connected with an exhaust fan (7). The exhaust fan is connected with the pulse filter and an air outlet. The pipeline is connected with a containing pipe (8). USE - Airflow crushing device for manufacturing graphene. ADVANTAGE - The device is easy to operate, and has simple structure and better crushing effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for manufacturing graphene by utilizing an airflow crushing device. DESCRIPTION OF DRAWING(S) - The drawing shows a pneumatic circuit diagram of an airflow crushing device.
