In the promotion of the use of graphene, the air classifier plays an important role

New materials are one of the foundations of the automotive industry, and behind every technological breakthrough, there must be innovation and change in materials and processes. Graphene has the potential to promote the transformation of the new energy automobile industry. Graphene has a high specific surface area and good mechanical, electrical, and thermal properties. It is an excellent material option and can be used in electrification, intelligence, and lightweight. Promote the automotive industry in all directions. The promotion and use of graphene is inseparable from the powder equipment industry, and the air classifier plays an important role.

In the fluidized bed type air classifier, graphite is exfoliated by high-speed air flow, and a cyclone separator is further used as a classification device. The exfoliated graphite is separated from large particles by using its high specific surface area. The unqualified powder is returned to the crushing chamber, and the exfoliated graphite is further classified together with gas. Graphene sheets are obtained by classification by primary and secondary cyclone separators and separation by tertiary cyclone separators. The continuous and large-scale production of graphene sheets with uniform layer distribution is realized. Not only the number of layers is evenly distributed, but also the output is high, the cost is low, and the layer thickness meets the requirements in the fields of rubber reinforcement, plastic reinforcement, coating corrosion protection, lubrication, etc., which is conducive to promoting the large-scale application of graphene.
