[0035] Example 2
[0036] A method for preparing graphene, including the device for preparing graphene, further includes the following steps:
[0037] S1: Conveying graphite raw materials from the feed pipe 19 to the inside of the reaction box 6;
[0038] S2: Turn on the first motor 4 and the heater 11, and the first motor 4 drives the spiral blade 7 to rotate in the opposite direction, so that the graphite raw material is evenly distributed inside the reaction box 6, and the heater 11 heats the graphite raw material;
[0039] S3: The graphite raw material is dispersed through the leak hole 9 on the surface of the spiral blade 7, and at the same time, the graphite raw material is moved to the upper part of the reaction box 6 by the dial 8;
[0040] S4: Turn on the second motor 15, the counter-rotating second electric motor 15 drives the pulverizing wheel 13 through the second rotating shaft 14 to pulverize the graphite raw material, and simultaneously pushes the graphite toward the spir...
