Abstract: The carbon nanotube pellets according to the present invention are produced by using only a small amount of solvent and have increased apparent density. The present invention can improve the problems of the change of the content generated by scattering of powders and safety issues by using carbon nanotubes in the form of pellet rather than carbon nanotubes in the form of powder in composite materials. And since the density of the pellet form is higher than that of the powder form, transport, transfer and improvement become easier. Therefore, it can be more effectively applied to the manufacturing of composite materials.

Abstract: The method for producing carbon nanotube pellets according to the present invention can reduce the particle size of the carbon nanotubes contained in the pellet by a repetitive extrusion process to produce pellets having improved dispersion characteristics in a solvent. The present invention can improve the problems of the change of the content generated by scattering of powders and safety issues by using carbon nanotubes in the form of pellet. And since the density of the pellet form is higher than that of the powder form, transport, transfer and improvement become easier. Therefore, it can be more effectively applied to the manufacturing of composite materials.

Abstract: The present invention relates to a device for drying and collecting a product such as a carbon nanotube pellet or aggregate, which can accelerate solvent evaporation by inserting and dispersing high temperature gas into a drying column as well as by a heat source inside and outside of the column, and can quickly remove the evaporated solvent. Further, the device can be used for drying and collecting processes while minimizing product breakage by regulating the gas flow rate and controlling flow of the product in the column. Thus, the device can be effectively applied to mass production of a carbon nanotube pellet product.
