  • Patent number: 11702522
    Abstract: A polymer-based spherical powder preparation device and preparation process are disclosed. The preparation device comprises a mill milling system and an inductively coupled plasma powder spheroidization system. The mill milling system of the preparation device can achieve ultra-fine grinding of the material at room temperature by applying strong extrusion, shear and circumferential stress to the material; and the inductively coupled plasma powder spheroidization system using high temperature plasma as high temperature heat source, the polymer powder can be heated uniformly, and the melting and cooling rate is fast, so the spheroidization can be completed in a short time. The preparation process of polymer based spherical powder was integrated and continuously produced by the preparation device.
