[0002] After the graphite oxide is ground to a certain fineness, it can be peeled off through liquid phase mechanical exfoliation to obtain graphene. The principle is that the ground graphite oxide is expanded under high pressure and then peeled off into graphene fragments under high-speed rotation. The graphene is then extracted and packaged to obtain the finished product. Therefore, a grinding equipment is needed to grind the graphite oxide into fine powder.

When the fan is running, air enters the shell from the air inlet, carries the crushed graphite oxide, enters the cyclone separator through the fan and the conveying pipe, and enters the storage bag after separation by the cyclone separator.
