Description

[0002] Graphite is a mineral composed of carbon elements, with the characteristics of soft, blackish gray, high temperature resistance, excellent electrical and thermal conductivity, and relatively stable chemical properties.

[0003] The production and transportation of graphite powder usually adopt pipeline transportation, and the transportation of graphite powder in the pipeline is mainly realized through a pneumatic conveying system. This method has the characteristics of high efficiency, environmental protection, flexibility, etc.

[0004] During the conveying process of graphite powder, due to the friction, shear force in the pipeline and the interaction between the materials, the graphite powder particles may be bonded, and then form lumps. These lumps may block the pipeline and affect the conveying efficiency. In the prior art, the pipeline may be heated to reduce the graphite lumping phenomenon, because graphite powder has good fluidity at high temperature. If the temperature in the pipeline is too low, the graphite powder may solidify or become viscous due to cooling, thereby causing the pipeline to be blocked. By heating the pipeline, the fluidity of the graphite powder during the transportation process can be maintained, and the solidification or blockage of the graphite powder can be prevented. In some process, the graphite powder needs to be transported and processed within a specific temperature range. By heating the pipeline, the graphite powder can be ensured to be maintained within the required temperature range during the transportation process, meeting the process requirements.
