NOVELTY - The purpose of the utility model is to provide a kind of colloid mill device for continuously preparing graphene material, comprising a grinding system, a separating system and a circulating system; said grinding system comprises a motor (6), a main shaft (5), a rotor (2); the rotor (9), stator (4), stator (7), said separating system comprises a toothed disc (10), a collecting tank (15), a discharging valve (13), the circulation system comprises a drainage pump (12), circulating pipe (14); circulating valve (11), inverted cone rotor and the forward tapered rotor by designing so that the graphite gradually under the action of grinding to fine layer peeling in the inverted cone along the cone-shaped rotor rotating after crushing. Especially it is designed with a toothed disk inner edge is thin teeth; the outer edge is thick, teeth grinding material by a drainage pump to circulate grinding, grinding fine material into the collection pool, through the fine material separated in time, so as to realize continuous and large-scale efficient preparation of high quality graphene.
