MAIC (Magnetically Assisted Impact Coating

The system relies on a pounding process in which small magnets in an oscillatingmagnetic fieldare fluidized to rapidly force the coating material onto the larger particles. Likewise, the magnets will distribute a small amount of liquid, such as an organosilane, evenly onto core particles and robustly apply them to the surface.
