MAIC, pronounced “mace,” is a patented process used to coat smaller particles onto larger particles or to apply small amounts of liquids onto particles. The system relies on a pounding process in which small magnets in an oscillating magnetic field are fluidized to rapidly force the coating material onto the larger particles.
