Utilizing a three-dimensional ball mill (three-dimensional reactor), conventional two-dimensional rotating equipment has problems of heat generation due to shear heat, heat generation due to impact, specific gravity difference, and viscosity difference. Mixing is performed. The realization of uniform mixing of organic and inorganic substances changes to an innovative material that compensates for both weaknesses. Utilize this technology to create innovative materials such as secondary battery materials, electronic materials (capacitors, conductive pastes), inks, and abrasives.
