4) the secondary grinding steel screen structure (51) rotates continuously, water starts to be supplied to the water spraying sleeve (26) through an external water inlet pipe (55), water is sprayed out of the water discharging hole and then used for cleaning raw materials in the secondary grinding steel screen structure (51), then waste water falls into a waste water tank (6), and then the raw materials are vibrated by the second filter screen (16) and are sent into the third-stage grinding steel screen structure (52) for cleaning again;
5) in the three-stage grinding steel sieve structure (52), as the raw materials are sent between the inner ring steel sieve (27) and the outer ring steel sieve (28), the grinding wheel (30) is driven by the motor III (56) to rotate between the inner ring steel sieve (27) and the outer ring steel sieve (28) to grind the raw materials, water is supplied to clean the raw materials, and after the grinding is finished, the raw materials are discharged into the heating barrel (13) through the outer ring steel sieve (28);
6) the heating barrel continuously heats, meanwhile, the motor five (14) drives the stirring rod (19) to continuously stir the raw materials, the raw materials in the heating barrel (13) are loaded into the ultrasonic equipment after a certain amount of raw materials are loaded, and then the raw materials are treated, and finally graphene powder is obtained.
